LASTEEK RWE300 is a ready to use water based, thixotropic, cold applied, and bitumen emulsion modified with solids SBR (Styrene Butadiene Rubber) latex. It is highly adhesive & it forms a seamless, highly elastic and durable film that adheres well to most of the common substrates.
LASTEEK RWE300 can be applied by brush, roller or squeegee. Hot dry or very porous substrate should be dampened with clean water prior to application of LASTEEK RWE300. For vertical application, it’s recommended to apply the coating in multiple layers in order to avoid sagging of the heavy bodied coating. This can be best achieved by maximum rate of 200 microns per coat. Ensure that the preceding coat is fully dried before applying the successive coat, which should be applied at right angle to the preceding coat. All application should be continued up verticals to the existing damp proof course. Where the surface is to receive a render or plaster finish a keyed surface should be form by gritting the second coat with clean dry sand. Allow a minimum of 48 hours drying period before applying a render, plaster or floor screed. On all weak points such as cracks or around the pipes use a woven fiberglass mesh/geotextile as reinforcement between the two coats of LASTEEK RWE300.
Tools can be cleaned with water as long as the product is wet. Once dry, by mechanical means only.
