Applying Firefree 88 paint is a straightforward process when following the recommended guidelines from Firefree Coatings Inc. This high-performance intumescent coating is designed to slow down the spread of fire by expanding when exposed to high temperatures, creating a protective char layer. To ensure optimal performance and compliance with fire safety standards, proper surface preparation and application techniques are essential.

Surface Preparation:
Before applying Firefree 88 paint, make sure the surface is clean, dry, and free of dust, grease, oil, or other contaminants. For previously painted surfaces, remove any loose or peeling paint. Surfaces such as wood, drywall, lath and plaster, metal, or other construction materials may be compatible, but always check Firefree’s application guide for approved substrates.

Priming:
In most cases, a primer is recommended to ensure better adhesion and durability. For non-porous surfaces like metal, a suitable rust-inhibitive primer should be used. On porous materials such as wood or drywall, a quality water-based or acrylic primer may be applied. Firefree Coatings can recommend compatible primers based on your project requirements.

Application:
Firefree 88 paint can be applied by brush, roller, or airless spray. Stir the product thoroughly before use. Apply in even coats and allow sufficient drying time between coats as per the product’s technical data sheet. Multiple coats may be necessary to achieve the required dry film thickness (DFT) for certified fire protection levels. Always use a wet film thickness (WFT) gauge to ensure accurate coverage.

Topcoat:
A topcoat is optional but may be recommended for aesthetic purposes or to enhance durability, especially in high-traffic or exterior environments. Firefree Coatings offers a list of compatible topcoats that won’t affect the performance of the intumescent coating.

Firefree 88 paint must be applied according to Firefree’s specifications to meet building code requirements and maintain its fire-retardant properties. Always consult the Firefree 88 Application Guide and test in small areas before full application.
