DULUX AcraTex AcraSilane

Code: 194-85741

DULUX AcraTex 964 AcraSilane in a non film-forming penetrating surface treatment that chemically bonds within the masonry pore structure to create a hydrophibic surface on bare unpainted brick, stone and concrete block, aerated autoclaved cement, fibro cement, and similar mineral based porous surfaces. DULUX AcraTex 964 AcraSilane penetrates into the pores and forms an invisible film which protects against moisture ingress

Features

  • Repels water
  • Invisible film
  • No priming needed

Benefits

  • Minimises dampness in porous surfaces & protects against moisture
  • No change in the appearance of masonry
  • Apply direct to bare masonry

Use and typical specification

Use DULUX AcraTex 964 AcraSilane to reduce water absorption on unpainted brick, stone and concrete block, aerated autoclaved cement, fibro cement, and similar mineral based porous surfaces. DULUX AcraTex 964 AcraSilane penetrates into the pores and forms an invisible film which protects against moisture for several years. Dependant on the porosity of the substrate multiple saturation coats may be required.

Typical properties and application data

Application Guide DULUX AcraTex 964 AcraSilane is applied to the surface by saturation using a hand pressure spray applicator or HPLC spray equipment . The product should be applied as a stream which runs down the wall approximately 10 - 20 cm. A second application should follow 1-2 hours after the first application. The object is to saturate the surface so that the product can penetrate as far as possible into the surface. For full details refer to individual Duspec Product and AcraTex Applicational Data Sheets.
