Product Name:T-Silox


T-Silox is a solvent-free, 100% silane/siloxane concentrate used to produce penetrating water repellent sealers for concrete, brick, natural stone and other masonry substrates.

Recommended Uses:

When diluted with an appropriate organic solvent, T-Silox will produce a penetrating colourless water repellent treatment of masonry substrates such as concrete, clay brick, cement mortars/renders, tiles and grout, and natural stones.T-Silox can also be used as a damp coursing fluid after dilution with a proper organic solvent for the installation of a silicone damp course in a masonry wall.T-Silox may also be incorporated into solvent-based acrylic formulations to produce products that are impregnating/coating combinations.

The important features & benefits of T-Silox include:

  • Deeply penetrates into masonry substrate.
  • Permanently bonds to the substrate with no peel or blister.
  • UV, alkali stable and durable formulation.
  • Reduces water penetration, efflorescence and water-borne staining.
  • Does not significantly change the surface appearance or vapour permeability.
  • Provides a good surface water repellent beading effect.

As masonry materials vary significantly, a test MUST be carried out prior to application to determine the suitability of this product for the purpose.
