Diamond Render Sealer is a water based Silane Siloxane sealer that is meant for sealing all cementitious and porous mineral products like render, skim coat, grout, concrete and natural stone.

The Sealer is a penetrating non-film making type that leaves a matt surface. The sealer leaves the surface permeable for water vapor.

The sealer improves water resistance, prevent efflorescence and lower material porosity.
