ACCESS® B-WB is a water-based water-repellent emulsion that is highly effective for mineral substrates. The product is an emulsion based on silanes and modified polysiloxanes, with properties including high water-repellency, strong beading effect, and low tendency to soil. The impregnating agent is highly penetrating and does not affect water vapor permeability. ACCESS® B-WB is solvent-free and prevents soluble salts from blooming. The product is milky white and has a specific gravity of ~0.95 g/cm3 at 20°C.

Applications & Uses

Application Method
Product Applications
  • ACCESS® B-WB is an excellent impregnating agent for many mineral materials, e.g. brick, cinderblock, sandstone, natural stone or mineral plaster. Depending on the absorptive power of the substrate, ACCESS® B-WB can be diluted with water in a ratio of 1 : 4 to 1 : 9.
  • Apply a uniform and rich coat of the dilution to the absorbent surface with a brush, roller or by flooding. To avoid omitted places, two applications wet-on- wet are possible. For mass waterproofing and to prevent salt blooming, we recommend adding 0.1 - 1.0% ACCESS® B-WB, related to cement weight.
