Greenseal Polydek

Polydek is a high performance, liquid-applied waterproofing membrane of styrene acrylic polymer. It consists of a very elastic polymer with the inherent flexibility that allows the membrane to accommodate movements in the substrate. It works as a seamless membrane that performs and adapt to any construction requirements in varied climatic conditions. Greenseal Polydek is supplied in 20 Liter Pail.

Polydek is especially formulated to seal, waterproof and decorate exterior surfaces & roofs. It seals cracks and joints in old or new roofs /walls and simultaneously leaving a seamless finish to the roof surface. Due to its versatility, it can be practically applied to any supported substrates like concrete, asbestos cement, fibre cement and on existing membranes.
