Roof Coat

A roofing compound based on special acrylic emulsion, which cures to form a flexible waterproof membrane.

Can be used on a variety of roof substrates including concrete, asbestos, tiles etc. The cured membrane has outstanding bonding properties, elasticity and tensile strength to accommodate substrate movement. Helps to insulate the buildings from the high outside temperatures.

It is also used to fix reinforcement mesh over Butyl tapes.

DIRECTIONS FOR USE

Stir the contents well before use. If applying on new concrete, dilute the first coat 30-40% with clean water to act as a primer. Apply two coats by roller or spray at right angles to each other. For best protection, press a layer of glass fibre reinforcing onto the first coat while still wet.
