Colourless water based and repellent protective for extiriors

Ard Rep W

ARD REP W is a super hydrophobic protective in emulsion based on silane and polysiloxanic compounds. It offers optimum impregnation for the most common absorbent mineral materials found in the building industry. ARD REP W reacts with substrate humidity forming a water repellent barrier without altering the porosity of the substrate & the water vapour permeability.

Ard Rep W - impregnante idrorepellente per esterno - Ard Raccanello

Technical features

ARD REP W inhibits water penetration and the progressive crumbling caused by repeated freezing/thawing as well as the unpleasant white patches deriving from the soluble salts extracted from the walls. Furthermore, this product does not alter the original aesthetics (colour & gloss) of facades.

These features make it an excellent water repellent treatment for vertical mural surfaces in general (concrete, plaster, bricks, wooden or asbestos cement panels & stone).
