Protectosil® 300 S

Protectosil® 300 S is a clear penetrating breathable VOC compliant surface treatment which protects concrete surfaces against deterioration.

Protectosil® 300 S is a solvent-free silane treatment that penetrates into the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. It creates a deep hydrophobic layer which prevents the ingress of water and water-borne contaminants from entering the substrate and causing premature deterioration.
