FEATURS & BENEFITS Crack Prevention - The improved flexural strength prevents crack generation. Hardness - It improves the surface’s hardness and prevents dust generation. Shrinkage - It reduces the drying shrinkages. Bonding - It provides improved bonding for concrete, mortar, for new constructions as well as repair works Erosion & Corrosion - It reduces erosion and corrosion. AREA OF APPLICATION Waterproofing: Good as an additive for economical waterproofing of roof and terraces with protective screed on top As bond coat: The bond coat provides better adhesion at the interface of old to new concrete and mortar substrate Repair works: It provides better adhesion and waterproofing in repair works Pinhole treatment: The bond coat is applicable for pinhole treatment of concrete surfaces External render: The external render provides a frost free waterproofing METHOD OF APPLICATION 1. Surface preparation Surface should be cleaned with a wire brush to remove dirt and loose particles. The surface should be free from grease, oil materials,loose particles laitance and dust The damaged portion of the concrete should be removed by saw cutting. If breaking is not possible then the surface should be roughened by wire brush or grit blasting After cleaning the surface should be saturated with potable water. The extra water should be removed before application 2. Waterproofing Application The composition of waterproofing coating is BONDSTAR SBR : Cement = 1:2 (by weight) Add cement on BONDSTAR SBR with gently mixing to avoid air entrapment Use a brush for application. Apply two coats of waterproofing slurry with a 3-4 hr interval (for surface drying) Protective screed should be applied with required thickness and slope
