The Difference Between Polyurea Spray Machines and Spray Foam Machines

Selecting the appropriate equipment is essential for any business that relies on spraying material to create insulation or coating projects. The ability to do an activity efficiently depends on the tools or equipment used; therefore, it is essential to know the various types of spray machinery that can do the task effectively.

Equipment for coating and spray machines does not have the same capability to work with specific materials and requires using a different pressure for the application. Most high-pressure equipment can be interchangeable, regardless of whether it’s employed to spray polyurea or foam; however, lower-pressure machines tend to be employed to spray foam. The correct material spread for coatings should be above 1850-3500 psi, and foam application is possible with machines that range from 800-2000 psi. However, the caveat is that lower-pressure machines can spray foam, but only when using long hoses since they require higher pressure to spread the material efficiently.

Air-Driven and Pneumatic Machines

Aero-driven or pneumatic equipment has been used for over 60 years, although the technology has advanced far in general effectiveness. The technology behind these machines is founded on a simple two-component system comprising two pumps with an air motor that operates within the limits of a certain pressure ratio. A machine’s pressure rating measures how much material it can distribute according to fluid pressure. For example, if its pressure ratio is 25, it can give 25 psi of pressure for each pound of air pressure applied.

If the host is big enough to distribute the required material, pneumatic systems can distribute the application consistently. It’s not surprising, therefore, that this type of technology has been used for many years and is extremely reliable. However, the main downside is that it doesn’t allow pressure to be effectively controlled, which puts the operator responsible for monitoring the foam to ensure proper application and application.

When businesses start, pneumatic equipment is often the best option because of its simplicity and lower cost. As the business grows up, larger jobs will need more efficient equipment.

Hydraulic machines

In the 70s hydraulic technology utilized hydraulic power to run chemical proportioning pumps. It is often used for the application of polyurea coatings and dual-component foam. Some systems contain a valve that allows directions for the sprayer to shift. The quick changeover of the pump is the most desirable characteristic, leading to little pressure loss as the direction change occurs.

Because the chemicals employed in spray foam must be mixed before application, The hydraulic application permits more effective monitoring techniques to ensure that the mix of chemicals is even and consistent throughout the application. Suppose the system can detect improper mixing or improper operation. In that case, the system shuts down automatically to avoid poor product distribution, allowing the operator to fix the issue rather than applying the wrong product.

Polyurea and foam chemicals are required for an optimum temperature of between 100 to 180 degrees F. Primarily, heaters warm the chemicals to required temperatures, and the hoses heated by them maintain the temperature set point to ensure the highest quality foam is added through these high-end hydraulic systems.

For applications requiring large areas, like coating large rooftops, using the hydraulic device for spray foam has proven to be extremely efficient, with the highest heat output and efficiency.

Electric Machines

Electric spray systems provide outstanding performance when high throughput is required in a coating and spray foam application task and are ideal for those looking for polyurea equipment to sell.

Electric machines can be advantageous due to their ability to maintain consistent pressure while activated. The spray or coating applicator is turned on to maintain the proper stall pressure levels even when the machine is turned on but is not in operation.

Motor control technology ensures that both mixing pumps have the same volume of fluid pressure and regulates the motor’s electric current. Pumps and applicator orifices are alike in size. Therefore, the two pressures on the pumps have to be similar to ensure a 1:1 chemical ratio. Modern technology will stop operation if pump pressures begin to drop out of sync and begin to lose equilibrium, preventing an individual from spraying poor foam or coating and causing an error notifying the user of the reason behind the shutdown.

The heating component of electric machines is also extremely useful. To function, the electrical spray foam systems heat the chemicals until they reach their required heating point using huge primary heaters. Although most contractors depend on hoses to keep the product’s temperatures when sprayed in colder temperatures, they can cause insulated hoses to cool and cause them to have to be warmed up before retaining heat. If the machines had been off for a prolonged time before the hoses reached the point that they could keep the temperatures necessary for heat retention, an enormous amount of time could have been lost.

Electric systems are reliable and can have long longevity if properly maintained. These systems have been proven to last from 15-20 years. They’re an investment, and maintenance can be costly, but they will be more affordable than purchasing a fresh piece of machinery.


If you’re looking for either used or new polyurea spray equipment available for sale, there are plenty of options suitable for all kinds of projects in this. If you want to purchase an available polyurea spray machine, look into options like the PMC polyurea machine and the Graco polyurea device. Suppose you want spray foam insulation, too; think about Graco and PMC foam machines.

Sanitation and hygiene are among the biggest problems facing the agriculture and food processing sectors. Businesses must ensure that agriculture and food products are processed in sterile conditions to decrease and minimize the possibility of spreading foodborne illness. In addition, maintaining agricultural facilities and operating expenses are often very high.

There’s a solution!

Utilizing food-grade coatings like Polyurea for the agriculture industry can help reduce the cost of these products while also enhancing hygiene practices that are safe and secure.

What is Polyurea?

Polyurea is a highly versatile protective coating for many residential and industrial projects. It is a great way to protect many materials against corrosion, rust, water damage, and other damage.

Polyurea is applied through sprays composed of an aromatic or aliphatic isocyanate component paired with a mixture of amines. The gel forms and becomes smooth and dry within moments, making a smooth, chemical-resistant, scratch-resistant, and waterproof surface.

Benefits of using Polyurea within the Agriculture Industry

Polyurea is an economical solution for protecting agricultural equipment, food processing facilities, and trucking equipment from unwanted contamination. Here are some benefits of using polyurea protective coatings for the agriculture industry.

It’s extremely durable.

Polyurea is one of the most flexible, durable, and robust protective coatings. Because of its polymer properties, Polyurea is also waterproof and abrasion-resistant. It is also chemically resistant. It is not likely to chip or crack when exposed to high-power pressure washing methods or exposure to powerful sanitizing chemicals. Some coatings may chip or crack when exposed to these techniques for cleaning and allow microbes to enter the cracks and multiply.

If you have a polyurea coating can help you to prevent this. Polyurea’s antibacterial properties guarantee that food processing facilities’ health and safety regulations are met easily.

It is a barrier against cold and hot temperature Changes

In addition to adhering to strict sanitation guidelines, another significant problem facing the beverage and food industry is storing food items at the correct temperature. Certain foods must be kept at specific temperatures to ensure their freshness, avoid becoming spoiled in transit, and to extend their shelf-life.

Certain products such as meat require freezing temperatures, drinks are best stored at cold temperatures, and items like tropical fruits should be kept at moderate to warm temperatures. Polyurea can stand up to a wide temperature range and isn’t susceptible to shocks caused by thermal. Polyurea can protect food processing equipment, facilities tanks, vehicles, and even tanks regardless of temperature or changes.

Environmentally Friendly

Pure polyureas are 100percent solids that are free of solvents and VOCs. They are eco-friendly coatings without odors or outgassing after installation.

Fast Return To Service

Installers who are certified apply Polyurea using a specific plural component and high pressure and temperature system by using the spray gun. It hardens within 6 seconds and can be applied with virtually unlimited applications, the thickness of one stroke. The area can be returned to service in one hour or so.

Different applications to Polyurea for Food Grade Coating

Polyurea protective coatings can assist in helping to save the food industry lots of time and money as they require minimum maintenance and work. Here are a few food industry applications of polyurea coatings.


Floor protection is among the most commonly used applications for polyurea protective coatings. Polyurea is the safety of a clean, safe, waterproof, abrasion-resistant, and chemically resistant surface for you to walk on. It can also be cured in a matter of seconds, which prevents lengthy shutdowns and ensures that operations can be resumed almost immediately.


Polyurea protective coatings protect against cold air disappearance, which leads to food spoilage and a rise in energy use or operating expenses for food processing facilities. They are also able to withstand very cold temperatures and not crack.

Food Processing Equipment

Not just the food processing and storage infrastructure needs protection from contamination–equipment is also a major risk. It is important to use food-grade polyurea protective coatings to prevent cross-contamination between equipment handling more than one kind of product because it is simple to clean. These coatings can also protect equipment such as feed troughs for farm equipment from wear and tear.


Silos are structures that are utilized to store large quantities of materials. Silos are used to store bulk materials. The agriculture industry includes grains, animal feed, and coal-based products such as cement, woodchips, sawdust, and many more. The items stored inside these storage facilities is referred to as silage. To avoid these products becoming damaged or exposed to potentially harmful contamination, the interior and the exteriors of silos must be sprayed with a tough polyurea protective coating.

What Polyurea can be used to make food and Beverage Tanks

Tank Lining

Polyurea offers a seamless and monolithic finish, which acts as a protective barrier against potential contaminants and food items when used inside the lining of tanks. This is particularly vital in the case of food delivery and transportation, where the danger of contamination is constantly the highest.

Garage floors are among the toughest work surfaces. It is often subjected to grease and oil as well as heavy-duty chemicals as well as heat, abrasion and massive mechanical loads. To guard your floor against all the things you throw at it, it is advisable to invest in a garage flooring coating. Particularly in Canadian winter, when garages face the added stress of the cold conditions and freezing temperatures and the uninsulated concrete of a garage floor may be damaged as well as make the space cold and unattractive. The garage floor coating can also provide a unidirectional finish that increases the security of the room and comes with a variety of appealing colors and finishes.

In this article, we will review the various garage floor coating options, including epoxy and polyurethane, and provide a list of garage floor paints and manufacturers in Canada.

5 reasons you need garage floor coatings

Although concrete appears to be indestructible it also requires some protection. The garage floor coating is a method to shield the flooring – it’s a cost-effective and durable method to build a tough-wearing surface that is able to withstand any demands placed on it by the area. In addition to being durable, there are additional advantages to the garage floor coatings.

  1. Cleaner It makes the surface less porous and stops the absorption of petrol, oil, and grease. It also has the advantage of being smooth and seamless
  2. Eliminates any imperfections in the flooring
  3. Improves security because it makes the flooring less slippery, as well as increasing the brightness of reflections through reflections
  4. Positively helps to the overall atmosphere of the garage.
  5. More affordable than other options for finishing garage floors (especially when using floor epoxy paint)

Polyurea floor paint and various garage floor coating types

Because of the need for toughness and durability Garage floor paints are typically polymeric coatings such as epoxy polyurethane as well as polyaspartic. Each of these three coatings has various strengths, as explained below:

Commercial garages tend to rely on epoxy garage floor coating due to its heavy-duty protection.

  1. Polyurea coating – The most popular coating used by the industry, polyurea is incredibly robust, hard-wearing, chemical and acid-resistant, abrasion-resistant, adhesive clean, and attractive.
    Ideal for commercial and industrial garages that are heavily used, if there is no danger of UV radiation exposure. In addition, applications for domestic epoxy floor paints are feasible.
  2. Polyurethane coating is often employed as a topcoat for the flooring made of polyurea or epoxy, it’s tough, abrasion-resistant, chemical resistant, UV-resistant, in addition to being more flexible polyurea (and therefore, less spongy underfoot).
    It is recommended for commercial low-traffic garages as well as home garages. Particularly suitable for concrete newly constructed flooring (where epoxy has a lack of flexibility ).
  3. Polyaspartic coating also referred to as an aliphatic polyurea Polyaspartic offers a unidirectional, hygienic surface, UV resistance as well as cold temperature application. chemical and water-resistant and an attractive, polished finish.
    It is recommended for medium to low traffic garages. Also suitable for parking spaces outside.

A floor coating made of polyurea is typically the best alternative unless there’s an issue that makes the use of polyurea unsuitable. These reasons include the use of newly laid concrete surfaces, exposure to ultraviolet, and the minimum time to cure (polyurea floor paint takes three days or more to cure, depending upon the amount).

Self-leveling epoxy floor paint

If you’re looking to have a smooth, seamless garage floor, and have some extra money to invest, a self-leveling or self-smoothing flooring coating is what you’re seeking. These floor coatings made of polymeric resin are put on the floor and then spread across the floor, allowing the coating to spread evenly across the floor’s profile. Self-flooring that is level coating is more durable the thicker it is used; for extremely heavy and heavy-duty use, it must be applied with 4-6mm. For medium-to-heavy duty applications need 2-3mm. The most well-known self-level flooring is polyurea floor coating. Canada has many companies that offer garage floor polyurea, for instance, Canadian Tire with RockSolid-products.

Garages are areas where harmful chemicals and oils are utilized frequently and, in the majority of cases, end on the floor. Concrete floors are a prime example of this, as these chemicals can get in and cause damage to the floor. When you apply a self-leveling coating on the floor, the floor is made seamless and is easier to work on, and highly durable to abrasion and impacts, and also the hot tire pick-up. Although polyurea is the most well-known, polyurethane is chosen for this purpose where the floor’s feel is essential or when there is direct sunlight exposure.

Polyurea coatings for garages

There are numerous garage floor coating manufacturers and suppliers that provide coats for Canadian customers. Canadian market. If you require polyurea floor coating, polyurethane, and aspartic there’s an organization that can meet your requirements. To get the best results, it is recommended to contact an expert. There is no substitute for an experienced professional who can apply the coating. For the application of garage floor polyurea, Canada has experts operating across all provinces.

Project Of The Week: Ice Rink Concrete Coating

gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw== - Project Of The Week: Ice Rink Concrete Coating

In the beginning of 2011, the design team of the new home for Canada’s Sports Hall of Fame in Calgary, Alberta, decided the floor of a hockey rink was the most effective choice to enhance their ice hockey exhibition. 

Who did they able to turn to for assistance? 

Polyurea Concrete contractors that utilized polyurea-based products to transform plain surfaces into real representations of water and ice.

Virtual Ice Rink at Canada’s Sports Hall of Fame Calgary, Alberta, Canada
A chance event caused Tyson Long, president of Calgary-based Hardscapes Inc., to the new home at Canada’s Sports Hall of Fame museum located in the city of Calgary’s Canada Olympic Park in which Tyson Long used clear and white Polyurea coatings that transformed the museum’s floor Ice Hockey exhibit space into a virtual ice skating rink.

Long was employed within the exact office in the same office building as Pacific Group Displays, a Calgary-based exhibit-display company that was contracted to design and construct the exhibits in the Canadian Sports Hall of Fame. Being familiar with the work of Long, an employee of the display firm approached him about the possibility of installing polyurea-made ice to the exhibit and he was willing to accept.

Utilizing polyurea products, which were embedded with the chopped fiberglass with red vinyl strips Long transformed the surface into a fake ice hockey rink in one week.

The basis for Long’s polyurea work comprised a concrete slab that was poured two inches below the floor in the exhibit’s adjacent hallways. In order to allow wheelchair access, the workers at Pacific Group Displays added 2 inches to the thickness of the floor by putting two layers of plywood on top of the concrete slab and then installing tracks to hold glass exhibits. The polyurea material was intended to be laid flush with the tracks’ tops so that they would have an even look to the foot of displays Long adds.

Two crew members laid down a layer of roofing material and metal mesh lath material to reinforce the material, then multiple coats were laid. Thin Finish with the broken fiberglass pieces included in the first coat to provide an additional layer of reinforcement. Long constructed”ice,” or white “ice” using three coats polyurea with a universal tint pigment, in Titanium White.

To make the ice hockey arena marks, Long and his crew used red vinyl strips that were supplied from Pacific Group Displays over White polyurea. “They wanted the design to look as real as possible,” Long says. “So We decided that we would embed the lines of the rink into the design as opposed to creating a painted-on effect.”

In addition to that to give the floor an even depth and “flooded” look, the builders added two coats of clear polyurea at 75 sq ft per gallon.

In the initial topcoat, they added a loonie Canadian dollar coin, which is thought to be to be a lucky charm for Canadian teams of curling and hockey participating at the Olympics. The legend of the lucky loonie is rooted in the 2002 Winter Olympics, when both the women’s and men’s hockey teams were awarded gold medals when an Ice rink maker placed an ice rink with a loonie that was used to host the event.

One of the challenges Long had to overcome in working on the track for the display. Long says to stop the polyurea from getting through the track, he had to fill the tracks with rods for the backer (foam rods used to seal joints that connect construction products).

Visitors got their first glimpse of the replica ice hockey rink that is a fitting tribute to the well-loved Canadian game, at the time that the Canadian’s Sports Hall of Fame building was inaugurated on Canada Day on July 1 2021.

The Showdown: Epoxy VS Polyurea Concrete Coatings

Suppose you’re looking to paint your concrete flooring, whether the garage floor or laundry room patio, there are two options: Epoxy or Polyurea. Both give your floors a shiny shine, but neither is pliable or impervious to impacts. This is what you should be aware of:

What is Epoxy?

The epoxy floor coating comprises the polyamine hardener as well as epoxy resin. The 100% solid epoxy coating gives a tough, shiny finish once it is dried, sealing porous concrete. Do not mistake the epoxy coating for Epoxy paint. The paint made from Epoxy is latex acrylic, with a small amount more Epoxy in the composition. The paint can be stained and peel. The epoxy coating can crack and chip over time.

What is a Polyurea?

Polyurea is a form of elastomer. If the word “elastic” comes to your mind, you’re starting to realize how Polyurea is different from Epoxy. Polyurea is more flexible and yielding. It also cures quicker, so be cautious if you’re contemplating using the polyurea coating by yourself. It won’t allow you the chance to rectify any errors. 

epoxy polyurea - The Showdown: Epoxy VS Polyurea Concrete Coatings

So, which is better: Epoxy or Polyurea?

Polyurea is the obvious winner. Because it’s more flexible, it moves along with concrete. It’s also stronger against impact and is a lot more robust than Epoxy.

Indeed, polyurea flooring is certainly not something you can DIY. Our experts carefully prep the flooring, removing stain and grease, and then fixing any spalled or damaged concrete as well as other processes. The preparation is the key to outlining a bond between the concrete as well as the coating.

The result is a beautiful, smooth garage flooring that is resistant to grease, oil, chemical, extreme heat, and tire marks. The polyurea coating is available in various colors and an amalgam of flakes so that you can personalize your flooring.

Make sure you consult the experts in Garage Flooring.

We are experts at Canadian Polyurea and we are proud to be confident in our experienced applicators and the high-quality and long-lasting coatings we apply to garage flooring. We are here to help you with any questions you have regarding concrete coatings.


Protecting Calgary’s Walkway’s With Polyurea

Calgary pathways 6 1024x1024 - Protecting Calgary's Walkway's With Polyurea

Calgary has the most extensive urban pathway and bikeway network in North America. The City maintains approximately 1000 km of regional pathways and 96 km of trails.

Enabling Calgarians to live active and healthy lifestyles is important to The City. Investments in active transportation infrastructure, including pathways and bikeways, provide Calgarians with active ways to travel through and around the City and reduce social isolation. Before the latest construction project was put into action, Calgarians were asked to pin the common destinations that they travel to regularly using the existing network. This information helped the building team identify what types of places people are traveling so that the technical experts could plan new pathways and bikeways to these locations across the City. Calgarians also told them about the various challenges and barriers they face while using the existing pathways and bikeways. They identified issues like off-set gates and posts that block the entrances to pathways, poor directional signage, poor maintenance, and missing connections, to name a few.

Cashing In On The Polyurea Market


In the ever-expanding sprayed-polyurea coatings market, the margin of error is incomparably narrower than for conventional coatings. While opportunities abound for contractors to jump on the polyurea bandwagon successfully, the growing variety of applications and the superior properties of sprayed polyurea need d attention given to the dispensing machinery involved.

The following explanation can quickly help any applicator understand the polyurea application process, the interplay between the various pieces of equipment, and the important design considerations of the pump, hoses, and spray gun. This experience can help open the door to a whole new market for coatings businesses that wish to advance their business.


The Newest Frontier in Coatings

Polyurea has become highly utilized for various applications previously dominated by epoxy, acrylic, and polyurethane. Specifically, the aliphatic polyurea compounds frequently find themselves as the coating of choice due to their superior mechanical properties.

Capable of smoothly adhering to substrates like cement, brick, and fiberglass, polyureas are now used for scores of building applications such as encapsulating asbestos ceilings or coating floors. Unlike polyurethanes, polyureas cure under high moisture and humidity conditions, as long as the correct surface preparation is undertaken.

Within the manufacturing and process industries, polyureas are now used in everything from the lining of storage tanks to covering shop floors and plant walls. Polyureas vastly outperform paint, which often cannot hold up to rigorous cleaning procedures practiced in pharmaceutical and food processing plants, for example. The remarkably fast reaction time (3 to 7 seconds) of polyurea systems appeals to facility management as it permits quick installation with only minimal disruption to process operations.

These performance benefits explain, in part, why the booming demand for polyurea systems should continue well into the future. “From what we’ve learned as an association, in addition to my interactions with applicators in the field and companies that manufacture the systems and the raw materials, I see a 15 to 20 percent growth per year in this industry,” says Dudley Primeaux, former president of the Polyurea Development Association and owner of Primeaux Associates LLC of Austin, Texas. As the prime inventor of sprayed-polyurea systems, Primeaux is well-positioned to provide consulting advice to contractors interested in entering the field.


A Little Background Knowledge Goes a Long Way

Polyurea systems are formed from the combination of two components: isocyanate and an amine resin. These components’ union forms an extremely flexible urea linkage, unlike the crystalline nature of polyurethane systems. The initial formulations were introduced in 1986 when somebody told Primeaux, then a chemist with Texaco Chemical Co./Huntsman Chemical, that polyureas couldn’t be sprayed. The system worked the first time because the equipment delivered both the A and B components in a predictable, consistent manner. 

The first commercial sprayed-polyurea coating was delivered for a roofing system in 1989, and the history of coatings systems has been forever changed. But the polyureas provide optimum performance only when mixed correctly, and according to Primeaux, choosing the right equipment to handle this task is critical.


The Challenge of Getting the Right Mix

No chemical catalyst is required, but special plural equipment is required due to the extremely fast reactivity and cure. High pressure is necessary to force the components to mix. High temperatures are also needed to lower the viscosity to enhance the mix and atomization. Heating occurs at the pump and the hoses, while the actual mixing takes place inside the components meet at high velocity. This mechanical mixing is critical to uniform concentration (hence, better adherence. The importance of obtaining equipment specifically designed to spray polyureas cannot be over-stressed.

The quality and the tolerances in the manufacturing of the spraying equipment make a huge impact on the output of your product,” stresses Primeaux. “Good equipment costs more, but this is not the place to skimp when you want to spray polyurea. The key to processing is within the proportioning pump and the spray gun. This is the ‘life support’ system for proper installation and application.”


It All Begins at the Pump

When spraying with polyureas, special consideration starts with the selection of a high-output pump. Increased pressure delivers more kinetic energy to the mixing zone. Pumps can be either pneumatic or hydraulically operated. Both types still require an air compressor because the air drives the drum pumps that deliver the material. The choice in pumps is then divided into either a vertical or horizontal layout.

The vertical pump has been the traditional choice of paint contractors. However, with high-solids coating systems like polyureas, verticals will not fill components of different viscosity at the same time and rate of speed. An imbalance of pressure will always be noted between the up and downstroke. This often results in a pulsating flow of material to the spray gun and affects the spray pattern and the coating consistency.

Polyureas must be mixed with an even and strong head of pressure. If the pressure varies on one side or the other, the quality of the mixed material and the spray pattern’s consistency at the gun can be adversely affected. And without sufficient volume, poor mix, atomization, and application result.


The hoses that carry the gun components must also be heated; otherwise, all the gains in breaking down the pump’s viscosity would be lost. Regular hoses, designed for polyurethanes, cannot handle the higher temperatures and pressures required for spraying polyureas. While the initial healing takes place within the pump, the hoses must maintain that temperature throughout their entire length — even as long as a football field. Such demands require specially designed hoses.

Primeaux added that, depending on the length, hoses should include a “step-down” inside diameter (ID) to minimize pressure drop at the spray gun. In other words, the ID at the pump end of the hoses is larger than the hose section near the gun.

The Spray Gun

Guns are divided into the categories, mechanical and air, depending on how the material is purged out of the chamber when detriggering occurs. Solvent purge guns are also occasionally utilized for hard-to-mix or off-ratio spray applications.

Representing the most applicable spray gun for the application of polyurea technology is the mechanical purge spray gun. With a machine gun, the valving rod’s return at detriggering seals off and completely flushes out the mixing chamber area. The tight fit of the valving rod, along with the high-pressure kinetic force of its movement, cleans all unwanted material out.

“The mechanical purge gun gives the best mix and properties, partly because of the dynamics within the mixing chamber,” says Primeaux. “You also get a complete purge out of the mixing chamber, which eliminates the possibility of the hold-up of product inside that chamber. The problem with hold-up is that it affects the incoming material and the subsequent mix.”

With air purge guns, a blast of air blows the material out upon detriggering between sprays. Here, the valving rod moves back and forth to allow air to enter the mixing chamber instead of just material.

The shortcoming of air purge guns is that since air is used to purge, the pressure must be consistently high to flush the chamber completely. If not, the tip will become plugged. An additional problem occurs whenever air enters the mixing chamber. Contaminants such as oil and water could be introduced from the air compressor onto the substrate. This can cause blistering and delamination of the polyurea coating.

Additional Gun Considerations

Other considerations when choosing a gun are gun geometry and construction. Maintenance and speed of operation also rank as important factors when selecting polyurea spray systems. Operator ergonomics should be taken into account as well. Finally, contractors new to the polyurea spraying industry should also seek an equipment manufacturer that provides good support and a commitment to maintaining a ready spare parts inventory.

Do the Job Right the First Time

Ultimately, contractors reap the benefits of knowing which equipment to use for entering the field of sprayed polyureas. On the other hand, the consequences of ignorance can put a contractor out of business.

When you’re working in the trenches with these applicators, you can see the results of using poor equipment right upfront. I know of one case where a guy did a job for a customer, but two things went wrong. The contractor didn’t do the right surface prep, and the equipment was not suitable for the field application of polyurea. When the coating failed, the customer sued the contractor several times for what the d was worth because of lost revenue.



Viaseal polyurea spray coat - SPRAY, COAT, AND CONTAIN

Traditional coatings have been too inflexible and not sufficiently elastic to accommodate ground, concrete, or metal substrate movement for primary or secondary containment. This deficiency can lead to cracks or holes forming in both the substrate and the coatings, which can compromise containment. However, the formulation of tough, monolithic, flexible coatings such as polyurea is now resolving this issue for contractors, engineers, and facility managers. When applied directly to concrete or metal surfaces, polyurea not only strengthens and protects lite underlying substrate but can also bridge gaps or cracks of 1/8″ or larger.

Furthermore, polyurea is now being applied to geotextile liners that can be swiftly rolled out in sheets to protect more heavily diminished surfaces or for use in field applications such as dirt or gravel pads at drilling sites. Once installed, applicators need only coat the liners’ seams to create a monolithic surface suitable for containment. Whether at refineries, industrial plants, or other manufacturing plants, regulations demand the use of primary and secondary containment systems to keep toxic or hazardous substances from escaping into the ground and potentially entering the water supply.


This implies primary containment is not foolproof. Though durable, metals corrode, concrete cracks, and is permeable, it will drain liquids if uncoated.
Therefore, secondary containment, in the form of concrete pits with barriers installed around the perimeter of a tank or other storage container, is often needed. To protect these structures, coatings such as epoxies, tars, and polyurethanes are often applied as an added protection wall. However, these traditional coatings are often inflexible when cured and can crack along with the concrete. Typical coatings do not hold up well to substrate movement or daily, seasonal, or process-related thermal expansion and contraction, which can lead to cracks and leaks.

After considerable research and testing, Collins says he turned to an advanced polyurea system from ArmorThane, a spray-applied polyurea manufacturer for primary and secondary containment. When applied to substrates such as concrete or steel, the spray-applied waterproof coating creates a durable, seamless, flexible, protective barrier that stops leaks and strengthens primary and secondary containment systems’ integrity. The coating exhibits superior physical properties such as hardness, tensile strength, and crack bridging and elongation up to 400% to create a robust, industrial-grade protective lining.

Polyurea can bridge cracks as well as flex at a rate similar to concrete and steel. This not only helps it last but also seals the concrete, so does Secondary containment, in the form of concrete pits tamers instated around the perimeter of a tank or other storage container, is often required as a back-up to primary containment does not absorb contaminants if there is a spill inside the contained area. While traditional coatings such as cementitious, epoxies, tars, and polyurethanes will prematurely fail if not installed under a relatively narrow range of temperatures, polyurea is designed for installation and use from ~4O°F to *35OCF. It sets and cures quickly and will withstand decades of freeze-thaw cycling and wide
After spraying the polyurea, return to service is almost instantaneous variations of temperature and humidity. After spraying the polyurea, return to service is almost instantaneous, making a big difference in minimizing production downtime.

They coated about 8,000 sq. ft. of concrete in 12 truck-offloading areas that required drive-in containment with ArmorThane polyurea. Within minutes of spray application, trucks were safely driving across it in some instances. Instead of spraying polyurea directly to the substrate, pre-sprayed composite panels can offer advantages for containment over the soil, gravel, or even concrete that is too damaged to be effectively rehabilitated.

Repairing plastic liners also presents a problem at the seams, when damaged areas are cut out and new sections. Polyurea products are so much more durable than plastics for containment systems. When needed, they can custom apply more polyurea millage to geotextile panels and berms to accommodate even the heaviest truck use and vehicle abuse. To verify the strength of the polyurea coating on containment mats and berms, in fact, Collins conducted several tests.

They also ran 6,044 fully loaded water trucks across a containment system, and it withstood it with zero holes and no compromise to the liner. Collins credits both the durability of the ArmorThane polyurea and its extended recoating window for the ability of his company to reuse its containment systems extensively. To reuse a containment system, they cut it up into rolls, roll it up and move it. Then, take it back out, respond to certain areas, and reinstall the original containment system at another location. They’ve found the extended open window for recoat and repair of the polyurea allows them to easily cut out any damaged section of geotextile, put a new piece in, and spray the seams to make it virtually seamless again. They get better repair and more reuse out of our containment systems.
