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.

SURFACE PREPARATION
The surface must be clean, dry and free from dust and other loose particles. All cracks, gaps, blowholes and joints must be filled prior to the application. For detailed information, please refer our information sheet on surface preparation.
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.
