Screedsure: The new name for RIW Screedsafe

Screedsure is a durable, wet room waterproofing membrane comprised of a unique copolymer top layer, with a self-adhesive butyl underside, giving an overall thickness of only 1mm.

Screedsure is quick and easy to apply with a working temperature range of +5°C to +35°C. It has no drying time and is therefore ready to tile immediately.

Screedsure should only be applied onto screeded and other solid concrete floors. For timber and similar substrates Tilesure Waterproofing & Decoupling Membrane should be used.
