Water – Repellent treatment is defined as the treatment of mineral substrates, especially facades of fair – faced masonry and cement, with hydrophobic impregnating agents. The purpose of water – repellent treatment is to protect exposed facades from moisture and attendant damage by applying a colorless, non – film – forming agent which prevents capillary uptake of water and the aggressive substances dissolved therein.
