Protectosil WS 800 P

Impregnation paste based on silane chemistry for the hydrophobation of dense building materials especially alkaline substrates such as


Protectosil WS 800 P

Protectosil® WS 800 P is especially designed for the water repellent impregnation of concrete or reinforced concrete (e.g. bridges, motorways, underground and surface engineering). Protectosil® WS 800 P may be used as a primer, as well. Protectosil® WS 800 P is applied as delivered and must not be diluted. It may be applied on dry and clean surfaces by common techniques such as rolling, brushing or airless spraying. The consumption strongly depends on the absorbency of the substrate. The consumption can vary between 50 and 500 g/m2. We therefore recommend to determine the required dosage in small test areas prior to the final impregnation


Technical Information

Is suited for the hydrophobizing impregnation of porous, mineral substrates
Shows very high reactivity and resistance against alkali
Shows optimum penetration even in dense mineral substrates
Shows no formation of sticky silicone films
Gives invisible and water vapor permeable protection
Reduces significantly the uptake of water
Reduces the uptake of water soluble pollutants
Protects hair like cracks of up to 0,3 mm
Is applied undiluted
Has a long contact time with the substrate due to its paste-like consistency thus allowing for very high penetration depth, reducing loss of material by run-offs, and facilitating overhead applications
