When it comes to large-scale construction or remodeling projects, clear communication between architects, contractors, and installers is essential. That’s where spec writing comes in. Specifications, or “specs,” define exactly how materials should be installed, tested, and maintained — including epoxy flooring systems. For commercial, municipal, and high-end residential projects, these specifications often follow a standardized structure known as the CSI format.

At Superior Garage Floors USA, we help builders, designers, and property owners across Phoenix, Scottsdale, Mesa, Chandler, and Gilbert ensure their epoxy flooring specifications meet performance requirements while aligning with the Construction Specifications Institute (CSI) format.

Whether you’re drafting a new bid or confirming compliance for a project, understanding the basics of CSI spec writing for epoxy systems ensures accuracy, quality, and long-term performance.

What Is CSI Format

The Construction Specifications Institute (CSI) developed a standardized organizational structure for writing construction project specifications. The system, known as MasterFormat, divides construction information into 50 divisions, each covering a category such as concrete, finishes, or electrical systems.

Epoxy flooring typically falls under Division 09 – Finishes, and more specifically under Section 09 67 00: Fluid-Applied Flooring. This section outlines requirements for epoxy, polyurethane, and resin-based coatings used on concrete substrates.

Why CSI Format Matters

CSI format provides clarity and consistency across all trades involved in a construction project. When epoxy flooring specs follow this format, they help ensure:

• Clear communication between architects, contractors, and installers.

• Defined performance criteria for durability, thickness, and appearance.

• Compatibility between materials and substrates.

• Reduced risk of misinterpretation during bidding or construction.

By using CSI standards, project teams can ensure that epoxy floors meet the same quality benchmarks every time.

The Three-Part CSI Specification Format

CSI specifications are typically written in three main parts. Here’s how those parts apply to epoxy flooring systems.

Part 1: General

This section covers the administrative details of the project. It outlines the scope of work, related standards, quality assurance, submittals, and warranty expectations.

For epoxy flooring, this includes:

• Project scope (area, substrate type, coating type).

• Applicable standards such as ASTM D7234 (pull-off adhesion testing).

• Required mockups or test areas.

• Warranty terms and maintenance guidelines.

Part 2: Products

Part 2 details the materials to be used — including brand, product type, and performance criteria. This section ensures that only approved epoxy systems with proven results are installed.

Typical inclusions:

• Product name and manufacturer (for example, Sherwin Williams or similar).

• Primer, body coat, and topcoat descriptions.

• Mix ratios, solids content, and VOC compliance.

• Required slip resistance or DCOF (Dynamic Coefficient of Friction).

At Superior Garage Floors USA, we often reference Sherwin Williams epoxy paint floor systems or equivalent high-performance materials that meet these criteria for strength, adhesion, and durability.

Part 3: Execution

This section outlines how the epoxy flooring should be applied. It includes details such as surface preparation, mixing, application techniques, and curing conditions.

Typical requirements include:

• Shot blasting or diamond grinding for surface prep.

• Primer application method and coverage rate.

• Environmental conditions (temperature, humidity).

• Number of coats and required film thickness.

• Final inspection and testing criteria.

This section ensures that the finished epoxy floor performs to specification and appearance standards.

Common CSI Sections for Epoxy Coatings

While epoxy flooring most commonly appears under Section 09 67 00, related CSI divisions may reference specific applications:

• 03 35 00 – Concrete Finishing: For epoxy coatings applied directly to structural slabs.

• 09 96 00 – High-Performance Coatings: For chemical-resistant or specialty resin systems.

• 13 05 41 – Corrosion-Resistant Coatings: For industrial or laboratory settings.

By aligning with the correct division, project teams ensure the specification is clear, accurate, and enforceable.

Benefits of Writing Clear Epoxy Specifications

Well-written epoxy specifications prevent delays, change orders, and costly errors. Clear specs also help:

• Ensure installers use the correct products.

• Guarantee compliance with safety and performance standards.

• Simplify the bidding process for contractors.

• Protect the owner’s investment through proper documentation.

In Arizona, where heat, dust, and moisture can challenge flooring systems, a well-documented spec helps avoid premature wear or adhesion issues.
