The product is designed to reface and even outvariations in concrete and masonry surfaces and bridgeshrinkage cracks. It provides a seamless, flexible waterproofcoating suitable for water tanks, reservoirs, drainage culvertsbasements and roofs.

2 The product provides a tough durablewater resistant coating which can withstand light pedestriantraffic and also has excellent weather resistance for Excellent barrier to carbon dioxide, chlorideand sulphate ions. Allows water vapour to escape from the structure. Waterproof-suitable for water retaining structures. High resistance to the effect of long-term weathering,durable in all climate conditions including UV attack. Non toxic - ideal for potable water tanks. Flexible, with thermal expansion similar to concrete. Excellent bond to concrete and masonry. Good crack accommodation capacity. Minimum surface preparation needed and low complianceTested to ASTM D4060, ASTM D4541, ASTM D638,ASTM RFX is a two component acrylic polymer modifiedcementitious coating which consists of Brushbond RFX powderand Nitobond BBX acrylic emulsion.

4 Typically concrete surfaces canbe cleaned using high pressure water jet or grit blasting or byproper wire brushing. Spalled surfaces or those containinglarge blow holes, cracks and other such defects should berepaired using Renderoc concrete repair mortars.

Clean fresh water is added in theproportions shown below and mixing commenced with apropeller agitator attached to a slow speed drill (500pm). Thepowder component should be added gradually to the liquid toavoid lump formation and mixed for 2-4 minutes. BrushbondRFX should be immediately used after mixing.

Use a short stiff brush preferably 120-150mmwidth and apply the mixed material like application of Brushbond RFX should not be done if thetemperature of the substrate is below 100C. When applyingBrushbond RFX on hot substrates , over 300C surfacetemperature, saturate the surface with water. Apply BrushbondRFX in 2 coats to achieve 1mm thickness. The second coat ofBrushbond RFX shall be applied as soon as the first coat hasreached touch dry state.
