Np Water Repellent Solution

Water Repellent Solution (EF) is a solvent-based impregnating agent based on silane/siloxane mixture. It serves as high-quality impregnating agent for exterior concrete protection and also can be used as a primer for silicone emulsion paint for masonry substrate.  It can reduce the capillary absorption of construction materials without blocking their pores and capillaries. Therefore, it will not affect the diffusion permeability. As a result, water vapour can escape unhindered from the masonry, and any damp can dry out.

Product Features:
• Excellent depth of penetration, creating a broad water-repellent zone 
• Excellent resistance to alkaline and efflorescence – the hydrophobic zone prevents salt, water and alkaline being transported from within the wall to the surface
• Good water-vapour permeability does not affect the breathing behaviour of the substrates
• Prevent damage caused by Chloride-induced reinforcement corrosion
