Contego High-Solids Intumescent Paint

Safeguard your structural investments with Contego High-Solids Intumescent Paint, the industry-leading fire barrier designed to deliver uncompromising safety without sacrificing aesthetics. Engineered with advanced latex-based polymer technology, Contego provides a thin-film, ultra-smooth finish that looks just like high-quality primer, but reacts under extreme heat to save lives and preserve property.

Why Choose Contego Intumescent Paint?

When exposed to fire, Contego’s advanced formula undergoes a chemical reaction, expanding into a thick, cellular char barrier. This intumescent layer effectively insulates structural components, delaying thermal collapse and providing critical evacuation time.

  • Versatile Substrate Bonding: Formulated for maximum adhesion to structural steel, standard lumber, engineered wood, drywall, concrete, and even polyurethane foam.

  • Aesthetic-Grade Finish: Unlike gritty, industrial fireproof coatings, Contego dries to a smooth, crisp white finish that can be top-coated with any high-quality alkyd or acrylic paint to match your interior design.

  • Eco-Friendly & Safe: With a low-VOC, non-toxic, and completely odorless formulation, it is perfectly safe for application in occupied buildings, schools, and hospitals.

  • Certified Peace of Mind: Extensively tested and certified by UL, Intertek, and major global standards to meet rigorous fire resistance ratings (up to 2 hours depending on application thickness).

Ideal Applications

Whether you are retrofitting a historic timber loft, coating exposed commercial steel beams, or fire-rating residential drywall, Contego offers a cost-effective, labor-efficient solution. It applies easily using standard airless sprayers, rollers, or brushes, reducing labor costs and project downtime.

Protect what matters most. Choose Contego High-Solids Intumescent Paint for a beautiful, paper-smooth finish that delivers heavy-duty, certified fire protection when it counts.

Structural Fire Protection

Fireproof Structural Steel Without Hiding the Architecture

Contego High Solids RFB is an intumescent fire-resistive material designed to protect structural steel from extreme heat. During fire exposure, the coating reacts and forms an insulating char that slows heat transfer to the steel beneath.

Intumescent Protection

Reacts to elevated temperatures by expanding into an insulating char that helps reduce heat transfer to the protected structural member.

Designed for Structural Steel

Fire-resistance designs are available for common structural configurations including wide-flange beams, columns, HSS members and metal decking.

Thin-Film System

Provides passive fire protection while maintaining the appearance and shape of architecturally exposed steel.

Recognized Test Standards

Fire-resistance performance has been evaluated using recognized standards including ASTM E119, ANSI/UL 263 and CAN/ULC-S101.

Architectural Appearance

Smooth finished surfaces can provide a cleaner alternative to bulky fireproofing where structural steel remains visible.

Efficient Application

High-solids formulation is designed for professional airless spray application according to manufacturer application requirements.

Typical Steel Applications

Built for Modern Structural Fireproofing

Select the applicable tested design according to the specific structural member, fire rating and project conditions.

01

Wide-Flange Columns

Thin-film fire-resistive protection for structural columns where a listed Contego design applies.

02

Wide-Flange Beams

Protect structural beams while retaining their profile in exposed architectural environments.

03

HSS Columns

Fire-resistance designs are available for hollow structural steel sections under applicable tested assemblies.

04

Metal Deck Assemblies

Listed systems are available for qualifying composite metal deck fire-resistance assemblies.

Fire-Test Performance

Passive Fire Protection Engineered for Critical Structures

Structural steel can rapidly lose load-bearing strength when exposed to extreme temperatures. Intumescent coatings help delay heat transfer to the steel and maintain the required protection for the duration specified by the applicable fire-resistance design.

  • Fire-resistance designs available up to 3 hours
  • ASTM E119 fire-resistance testing
  • ANSI/UL 263 tested systems
  • CAN/ULC-S101 tested systems

Technical Information

Specify the Correct Fireproofing System

Fire-resistive coating thickness is not one-size-fits-all. It must be selected from the applicable design according to the member configuration, section factor and required rating.

Before You Order

Three Steps to the Right Fireproofing Specification

Properly specifying an intumescent coating starts with the structural member, not simply the square footage of the project.

1

Identify the Steel

Determine member type and size, such as W-beams, W-columns, HSS columns or the applicable floor/deck assembly.

2

Confirm the Fire Rating

Establish the required hourly fire-resistance rating and identify the tested or listed design applicable to the construction.

3

Calculate Required DFT

Determine required dry-film thickness from the applicable design before calculating material quantities or preparing a project quotation.

Frequently Asked Questions

Contego High Solids FAQ

Common questions about specifying and applying intumescent fireproofing.

What is Contego High Solids Intumescent Paint?
Contego High Solids RFB is a water-based, single-component intumescent fire-resistive coating. When exposed to elevated temperatures, the coating reacts to form an insulating char that helps slow heat transfer to the protected substrate.
Contego has fire-resistance designs covering ratings up to three hours. The rating available for a specific project depends on the structural member, applicable tested design and required coating thickness.
Required dry-film thickness varies by fire rating, structural member, section factor and design listing. There is no single coating thickness that is correct for every steel member or project.
Substrate preparation and primer selection must comply with the current manufacturer requirements and project specification. Use only compatible and approved primer systems where a primer is required.
Yes. Thin-film intumescent coatings are commonly selected when designers want to retain the appearance and profile of exposed structural steel while providing passive fire protection.
Topcoat requirements depend on the environment and project specification. When a topcoat is required, use a system approved for use with the intumescent coating and follow the current manufacturer instructions.
Material quantity should be calculated after determining the required dry-film thickness for every member included in the project. Send us your structural member information, required rating and approximate quantities for assistance preparing an estimate.
