FR Coating (Spray Grade) is an advanced ablative sealant designed to enhance the fire resistance and surface integrity of FR Boards. It’s applied directly to stone wool fibres, forming a smooth, flexible white finish that increases the board’s durability, reduces delamination, and prevents hot gas and flame penetration. Ideal for retrofit situations, it also supports acoustic performance and meets high indoor air quality standards — making it a clean, safe solution for commercial and residential builds.
