Product use: CROMAR PRO GRP Topcoat is recommended for use in flat roofing applications where regulations specify a fire-retardant system.

Characteristics: CROMAR PRO GRP Topcoat is designed for roller application which exhibits good levelling characteristics and sag resistance on inclined surfaces. The cured top-coat is tack-free and watertight with excellent water and weather resistance providing a maintenance-free surface.

Application: CROMAR PRO GRP TOPCOAT is designed for use at ambient temperatures between 18oC and 25oC, and requires the addition of 2% medium activity MEKP catalyst to achieve an efficient cure.
