KRISHNA FLEXO FALT is a high performance, ready to use, cold applied,single component and elastrometic high build liquid waterproofing membrance based on aliphatic, polurethane modifiedbitumen emustion. FLEXO FALT forms a seamless,highly elastic and durable films that adheres well to most common substrates e.g concrete,cement blocks,wood,existing roof felts.FLEXO FALT is highly resistance to a clorides and shlphetes commanly present in the soil.it is also highly UV resistant.
- New roofs
- Balconies, Terraces, Parking garages, Asbestos and concrete roofs.
- Industrial washrooms & shower.
- Water reservoirs and swimming pools.
- Foundation, cellar walls, retaining walls, bridges abutments.
- Refurbishing of old waterproofing system including torch - on membrane.
- Facade damp proofing.
- Water proofing / curing membrane and protective coating for sub structure.

SURFACE PREPARATION :
All surfaces should be sound, clean and free of contaminants. Absorbent surfaces e.g. concrete should preferably be dampened with water. In kitchens, toilets and other wet areas all the openings should be properly sealant. On all weak points such as cracks or around the pipes use a woven fibreglass mesh as reinforcement between the two coats FLEXO FAlT.
FLEXO FALT can be applied by brush, roller or sequeegee. Hot, dry or very porous substrate should be dampened with clean water proir to application of FLEXO FALT. When two or more coats are required, ensure that the preceding coat is fully dry before applying the successive coat, which should be applied at right angle to proceeding coat. FLEXO FALT also acts as a non-degradable curing membrane: hence it may applied immediately after the removel of mould, to the concrete structure, which has no aesthetic value such as the sub structure of the building.
