Colourless water based and repellent protective for exteriors

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.
