    Product Description

    High build fiber Reinforced Acrylic Elastomeric Waterproofing render for roofing.

    Brushbond Roofguard is high build fiber reinforced seamless waterproofing render suitable for waterproofing of old & new roofs, it is a polymer base product applied in three or more coats & each coat with different colors for monitoring correct thickness.The product can be applied directly on existing concrete, brickbat coba, and screed concrete even without removal provided the substrates are sound enough for application of the coating avoiding the risk of damage to the old roof associated while removing of the existing overlays. The product provides a seamless, tough durable water resistant coating which can withstand light pedestrian traffic and also has excellent weather resistance for exterior applications.


    • High Build system provides higher dry film thickness of more than 1mm in three coats.
    • The product can applied directly on existing sound concrete, brickbat coba, screed concrete even without removal
    • No protection screed required eliminating the additional weight due to protection layer
    • Excellent barrier to carbon dioxide, chloride and sulphate ions
    • Allows water vapour to escape from the structure.
    • High resistance to the effect of long-term weathering.
    • Durable in all climate conditions including UV attack.
    • Excellent bond to concrete and masonry.
    • Good crack accommodation capacity.
    • Minimum surface preparation needed and low labor.

    Brushbond Roofguard is a single component acrylic polymer modified, elastomeric fibre reinforced high build & easy roller applied / brushable coating available in different colours for application in multiple layers, minimum 3 layer application is recommended for best performance.

    Application Instructions

    Surface Preparation
    All the surfaces which are to receive Brushbond Roofguard must be free from oil, grease, wax, dirt or any other form of foreign matter which might affect adhesion. Spalled and deeply disintegrated concrete should be removed to sound concrete and repaired with Fosroc Renderoc System.

    It is recommended that new cementitious and concrete substrates has to be primed with Nitoproof WB primer.Nitoproof WB Primer is a two component product and must be mixed & applied in order to perform as specified. Transfer base and the hardener to a suitable fresh container and mix thoroughly with a slow speed mixer for 2 -3 minutes which makes the mix as a milky white paste. Add double the quantity of clean water by volume (4ltr water to 2ltr pack size, 12 liter water to 6ltr pack size) to the mix gradually under mixing which makes the mix as low viscous milky white liquid. Apply using a roller or brush. Do not apply on running.

    The contents of Brushbond Roofguard shall be thoroughly stirred for at least 2 minutes using a slow speed (300-400 RPM) drill machine attached with a mixing paddle. Re-tempering with water should not be done. Keep on stirring during application.

    For best results, surfaces should be damp. In order to obtain the protective properties of Brushbond Roofguard it is important that the correct rates of application are observed. Use a short stiff brush preferably 120-150mm width and apply the mixed material like paint.The application of Brushbond Roofguard should not be done if the temperature of the substrate is below 100C. Apply Brushbond Roofguard in 3 coats to achieve total dry film thickness of 1mm .
