RIW Cementseal Primer

Cementseal Primer provides efficient sealing of horizontal concrete substrates, by stabilising the surface and preventing out-gassing, prior to the application of Cementseal or Cementflex. The product will also act as a curing agent for newly placed cement based mortars and coatings, by helping to reduce the amount of water evaporating from the surface.

Cementseal Primer can also be applied to concrete surfaces to prevent leaching of free lime and/or mineral salts prior to installation of Cavity Drain type products.

The product chemically reacts with cement, to produce a durable surface seal, which stabilises the substrate and reduces the evaporation of water
