Design data/Durability

LASTEEK A500 is used as a liquid waterproof membrane. The product is especially developed for giving an elastomeric, monolithic seal, covering uniformly uneven profiles and protection of the substrate.  LASTEEK A500 provides protection against weathering, ageing and ultra violet radiation.

Uses

Waterproofing of flat or pitched roofs. (Asphalt, Asbestos, Cement tile, Terrazzo & Concrete).

Waterproofing of domes, arches, terraces, balconies, sunshades & parapet walls.

Waterproofing cum decorating coating for plastered walls.

Protective coating on polyurethane & polystyrene foam insulation.

Waterproofing over old refurbished roofs/existing bituminous roofs.

Waterproofing of metal roofs (aged galvanized)

Surface Preparation

All surfaces must be clean, dry, and free from Oil, grease, rust, peeling paint, curing compound and any loose materials.  The substrate should be firm, in case of gaps and cracks fill with suitable sealant (polysulphide) and ensure surface is even. If the substrate is porous, it is recommended to prime the substrate by diluting LASTEEK A500 with 20% water.

Application

Before use, stir well.  Do not apply if rain is expected within 24 hours. Apply the material on the surface using brush/roller or spray. A second coat is applied at right angle after the first coat is dry.  It is recommended to apply two coats of LASTEEK A500 to get a dry film thickness of 1.5 mm (approx.).  Embed glass fiber mesh/Geo textile around all corner joints, fillets, pipe penetration, pipes, over cracks, drains and where substantial movement is anticipated, lay Glass fiber/Geo textile mesh in the wet first coat before application of subsequent coats.

Clean tools with soap & water.
