Brushbond Roofguard page 1 of 2High build fi bre Reinforced Acrylic Elastomeric Waterproofi ng render for roofi ngUsesBrushbond Roofguard is high build fi bre reinforced seamless waterproofi ng render suitable for waterproofi ng of old & new roofs, it is a polymer base product applied in three OR more coats & each coat with diff erent colours 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 traffi c and also has excellent weather resistance for exterior applications.Advantages High Build system provides higher dry fi lm 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 eff ect 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 labour.Standards complianceTested to ASTM D4541, ASTM D412, ASTM G154, ASTM E96DescriptionBrushbond Roofguard is a single component acrylic polymer modifi ed, elastomeric fi bre reinforced high build & easy roller applied / brushable coating available in diff erent colours for application in multiple layers, minimum 3 layer application is recommended for best performance.Technical SupportFosroc off ers technical support service to specifi ers, end-users and contractors, as well as on-site technical assistance in locations all over the country.PropertiesSolid Content70 + 3%Tensile strength (ASTM D412) 1.10 MpaElongation (ASTM D12) 100%Resistance to ageing due to UV radition ASTM D4587 E 1000 hrs (No change)Rapid chloride penetration ASTM C 1202-03 Very lowPull off adhesion ASTM D45410.92 MPaResistance to Algae growth (ASTM D5589-97)Passes, Zero ratingPermeability (mm) (BSEN 12390 part B)5.0Water vapour transmission (ASTM E96)6.0 g/m2hNote: The typical physical properties given above are derived from testing in a controlled laboratory environment. Results derived from testing fi eld-applied samples may vary, dependent on actual site conditions.Application InstructionsSurface PreparationAll 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 aff ect adhesion. Spalled and deeply disintegrated concrete should be removed to sound concrete and repaired with Fosroc Renderoc System.PrimingIt 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 specifi ed. 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
