  • Deeply Enhances Surface Tone with Matte Finish
  • Water, Salt & Stain Resistant

  • Resists Biological Growth (Mold, Moss & Algae) Due to Superior Water Repellency
  • Breathable, Low VOC Water Based Sealer

SB-6400 Wet Look Penetrating Sealer is a low VOC, water based blend of silane/siloxane and polymers that chemically bonds to the substrate creating both a water and oil repellent finish. SB-6400 will seal and enhance the beauty of new and old surfaces with a luxurious, wet look, matte finish that enriches surface tone and color contrast. It is breathable and will not trap efflorescence, allowing it to be applied immediately after new paving stones are installed. SB-6400 improves surface durability and freeze-thaw resistance while protecting the surface from salt, acid, and staining from oil, food, and other contaminants. SB-6400’s water repellent feature will produce beading of water on the surface and will help to inhibit biological growth such as mold, moss and algae. SB-6400 has the consistency of water and is milky white when applied. Once dry, it will enhance color and contrast with a matte (while maintaining a natural look) finish.  SB-6400 Wet Look Penetrating Sealer can be used both inside and outside on old and new pavements. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (82°C).

Suitable Surfaces

Ideal for horizontal and vertical surfaces including cultured and natural stone containing quartz or other silicas. Also suitable for concrete, concrete and clay pavers, grout, unglazed tile and terra cotta. Not recommended for marble, limestone, agglomerate tiles and polished surfaces with a high gloss finish as they do not absorb the sealer.

A test area is always recommended to determine product suitability and compatibility with your specific surface before use and also if desired results are achievable. Due to the inherent variability of natural stone and clay products, long term performance may vary. Please consult with us prior to sealing if there are concerns.

Per gallon. For two coat applications apply wet-on-wet at right angles to the first coat using approximately two thirds of the estimated amount on the first coat and one third on the second ensuring saturation. Actual coverage may vary depending on the type, age, condition, porosity of the surface, application method and other local conditions such as temperature & humidity.
