H-102K It is clear water-dilutable potassium/sodium methyl siliconate solution. As a surface treatment in applications that utilize its ability to impart a water repellent surface and reduce water absorption. Designed to impart water repellency to a wide variety of substances,such as sandstone, limestone, marble, granite and bricks, ceramics,gypsum and gypsum-based plasterboard, light fillers etc.



Cement mortar, concrete:  ( H-102K: water = 1: 4-10 diluted, mix to cement mortar or concrete)

Masonry:  ( H-102K: water = 1: 15-20 diluted, soak masonry 15-20 minutes)

Building surface:  (H-102K: water = 1: 4-10 diluted ,brush directly to the surface of the building)

The siliconate reacts with carbon dioxide (CO2) in the air to form an insoluble water-resistant treatment within 24 hours.

It is also particularly effective in preventing humidity from rising within walls(rising damp). For this application the product is injected into the walls.
