The membrane consists of naturally flexible resins that are non-toxic and maintain their integrity over time. It is one of a stable of Acrylmeric products endorsed by CSIRO that also includes Weathertuff, ideal for bathroom walls, that is like a thicker, impermeable paint that comes in a range of colours or can be mixed to individual requirements. It comes in flat or textured finishes.
Also available from Colormaker is Acrylmeric Superseal, a primer coating that provides an excellent base for all Acrylmeric waterproof products and is a superior primer for recoating of conventional paints as well.
