SUPERIOR PROTECTION OF VERY POROUS BRICK, CONCRETE, NATURAL STONE AND TERRACOTTA AGAINST FREEZE-THAW / SALT SPALLING.
S-TECH 40SK™ is an impregnating, invisible fully breathable consolidator and silane water repellent. S-TECH 40SK™ is designed to protect softer, more porous building materials in a freeze-thaw or salt water environment and helps to consolidate friable surfaces. Denser, stronger materials may only require a water repellent, but S-TECH 40SK is recommended for very porous types of natural stone, brick, terracotta, paving and grout which are more prone to spalling damage caused by water freezing and dissolved salts. Treated surfaces become easier to clean, maintain and keep looking good for longer.
