TK 290 WB is a waterborne silane/siloxane, multi-substrate, salt, and water repellent. Engineered to prevent damage from environmental conditions including de-icing agents, salts, freeze damage, efflorescence, scaling, surface popping, and the damaging effects of acid rain. TK 290 WB is formulated to penetrate up to 1/8 inch (3.175 mm) and chemically bond with the substrate to become a permanent part, prohibiting salt, water, and chloride ion intrusion. This protection ensures the longest life-cycle to the substrate by preventing surface deterioration.

TK-290 WB is suitable for both vertical and horizontal, above-grade exterior surfaces. Typical surfaces include:

  • Concrete & Cementitious Surfaces
  • Pavers / Brick / Clay Brick
  • Precast Concrete
  • Poured Concrete Walls
  • Split Face Block
  • CMU
  • Synthetic Stone
  • Glazed Brick / Block
  • Gypsum
  • Stucco



  • Low VOC – Meets the VOC Regulatory Compliance for AIM, OTC, LADCO, CARB, SCAQMD, CANADA
  • Non-Film Forming – Maintains the surfaces slip resistance (coefficient of friction)
  • Non-Color Enhancing – Will not alter the appearance of the substrate and will not yellow
  • Performance – Outperforms typical water repellents due to superior penetration and bonding properties
