How to Bid Polyurea Projects: A Practical Guide for Canadian Contractors

Winning profitable polyurea projects requires more than technical skill — it requires a sharp business sense, an understanding of how to estimate accurately, and the ability to communicate your value to clients who may be comparing you to general painters or cementitious contractors. This guide walks through the key elements of bidding polyurea work in the Canadian market.

Understanding Your True Costs

The most common mistake new polyurea contractors make is underestimating their all-in costs. A rough material cost per litre is not a bid — it’s a starting point. Your fully loaded cost must account for:

• Material: Part A (isocyanate), Part B (resin), primer, and any topcoat. Don’t forget drum handling, waste disposal, and safety materials.
• Labour: All hours including mobilization, surface prep, masking, application, cleanup, and demobilization. Crew size and experience level matter.
• Equipment: Proportioner operating cost, hourly hose wear, tip consumption, and maintenance reserves. A $100,000 machine needs to generate enough revenue to justify its existence and eventual replacement.
• Overhead allocation: Vehicle, insurance, licenses, CPCA membership, certification renewal, and administrative costs divided across all projects.
• Travel and accommodation: Remote projects add real costs that must be explicitly included.

Estimating Coverage Rates

Theoretical coverage rates from manufacturers assume perfect conditions. In the real world, factor in:

• Overspray waste (typically 10-20% depending on wind, surface geometry, and applicator technique)
• Holiday and repair touchups (budget 5% additional material for typical projects)
• Surface absorption on porous substrates (porous concrete can absorb 15-20% more material than the theoretical spread rate)

A practical rule of thumb: add 20-25% to theoretical coverage to arrive at your material order quantity.

Understanding the Specification

Always read the full specification before bidding. Key items to confirm:

• Specified minimum dry film thickness (DFT) — verify your system can achieve this in the required number of passes
• Surface preparation standard (SSPC-SP levels) — prep is often the most time-intensive part of a project
• Primer requirements — some specs require specific primers that must be sourced separately
• Inspection and testing requirements — if the spec requires third-party adhesion testing, that cost belongs on your bid
• Warranty requirements — understand what you’re being asked to warrant and for how long

For projects involving manhole rehabilitation or water infrastructure, municipalities often have very specific inspection protocols that can add days to project timelines.

The Comparison Problem

Your most common competitive situation is not competing against another polyurea applicator — it’s competing against a cementitious or epoxy alternative. The specifier or client may not understand why your price is higher. Your job is to help them make an apples-to-apples comparison that accounts for:

• Service life: Polyurea’s 30-50 year service life versus 10-15 years for many cementitious systems
• Maintenance costs: Polyurea’s seamless, chemically resistant surface requires minimal maintenance versus periodic patching of cementitious systems
• Application speed: Polyurea often requires less total project time, reducing client disruption and resulting in faster return to service
• Lifecycle cost: When you do the math over 30 years, polyurea almost always wins. Build this analysis into your proposals.

Proposal Best Practices

A strong polyurea proposal includes:

1. Executive summary with your key value proposition
2. Scope of work clearly describing all surfaces, preparations, and systems
3. Material data sheets and product certifications
4. Your applicator certification credentials (CPCA membership, manufacturer certifications)
5. Reference project list with contact information
6. Warranty terms clearly stated
7. Payment schedule tied to project milestones

CPCA members can access proposal templates, pre-qualification packages, and technical documentation from our Member Resources portal.
