    Description

    Cromar PRO GRP Topcoat is a dark grey, pre-pigmented, isophthalic acid based, filled fire-retardant roofing top-coat that conforms to BS476 Part 3:2004, FAB classification. Recommended for use in flat roofing applications where regulations specify a fire-retardant system.

    Designed for roller application which exhibits good levelling characteristics and sag resistance on inclined surfaces. The cured top-coat is tack-free and water- tight with excellent water and weather resistance providing a maintenance-free surface.

     

    What is PRO GRP?

    GRP stands for Glass Reinforced Polyester and is also known as Glass-Fibre.

    This system is cold applied on site, giving it a seamless and flexible weatherproof finish that resists water, heat and frost.

    The resulting surface gives a strong architectural finish that looks very impressive. If maintained properly it will last as long as the building stands.

    Cromar have developed this technology further to produce the perfect all weather protection for any flat roof. PRO GRP can be applied in small domestic situations right through to large industrial environments.

    • COLD APPLIED - no heat required
    • EASY TO FORM - around complex situations
    • VERY DURABLE - resists heavy foot traffic

    Application


    For full application instructions download the PRO GRP Installation Guide.

    Cromar PRO GRP Topcoat is designed for use at ambient temperatures between 18℃ and 25℃, and requires the addition of 2% medium activity MEKP catalyst to achieve an efficient cure.

    For optimum performance the top-coat should be applied to a dry, dust-free surface and built up to film thickness of 500 - 600 microns to achieve the desired fire retardant characteristics in the finished structure.

    Before use, the temperature of the top-coat should be 18 – 25℃. For application at lower ambient temperatures a high activity MEKP catalyst can be used at an addition level of 2%.



    Coverage


    The values above are recommended coverage rates for estimating purposes we would recommend coverage rates or 1.5kg/m 2 for resin, and 0.5 kg/m 2 for top coat.

    questions Paul Pendleton on 2024-08-26 21:01:05
    Question: 

    Our builder used a Cromar Pro GRP Roofing Kit to cover our flat roof porch. The top coat coat has cracked in a couple of places. Am I ok to put another layer of Top Coat directly on top of the existing top coat. I have brushed it down and washed it, is there any other prep that I would need to do?

    Answer from Rawlins’ Technical Team:

    No, re-applying topcoat directly to a previous coating of topcoat wouldn't work in this instance.

    Assuming the existing coating is clean, dry, sound and lightly abraded, we'd recommend applying Acetone to the roof to clean the surface, followed by a thinly layered coat of Cromar PRO GRP Resin, before another coat of Cromar Pro GRP Topcoat to finish.

    Hi I have a grp roof which is going to be walked on what material should i sprinkle or mix in with the topcoat. Regards Mark
