Duram S900 4LT

Penetrative Waterproofing Sealer
Duram S900 is a clear (water white), non-glossy, deep penetrating waterproofing solution. It creates a waterproof barrier below the surface of porous substrates preventing the access of water. Duram S900 is a deep penetrating siloxane water resistant solution which penetrates into the tissue of porous substrates and creates a waterproofing barrier.

Designed to be applied to external concrete, cement render, block walls, sandstone, porous pavers and other porous surfaces.
Assists in preventing mould and fungus growth, and efflorescence (white salt spotting or leaching).

Coverage rate varies depending upon surface of substrate and application. Several coats are required to ensure that sufficient product has been absorbed.
