  • Breathable, Immediate Application:  Does Not Trap Moisture or Efflorescence

SB-4000 Water Repellent & Salt Blocker is a water-based silane/siloxane invisible penetrating sealer.  It can be used indoors and outdoors, on old and new, horizontal or vertical surfaces. SB-4000 can be applied immediately after most surface installations, as it is breathable and will not trap naturally occurring moisture or efflorescence. On new concrete, SB-4000 should be applied once concrete is fully cured (30 days after installation). SB-4000 protects surfaces from water penetration and salt damage from the use of de-icers or exposure to salt air. Due to its superior water repellency, SB-4000 helps to reduce biological growth such as mold, moss and algae. It is non-hazardous and VOC/EPA compliant. SB-4000 has the consistency of water, is milky white when applied and dries transparent on most surfaces.  Some surfaces may darken slightly. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (82°C).

Suitable Surfaces

Suitable for concrete and clay pavers, flat and stamped concrete, masonry, segmental retaining wall blocks, concrete walls and exposed aggregate. May be used on natural and manufactured stone containing quartz or other silicas, grout, unglazed tile and terra cotta. Safe to use on old or new surfaces in both inside and outside environments. Not recommended for granite, marble, asphalt, slate, agglomerate tiles, glazed or ceramic tile. Performance may vary on limestone. Test first to verify performance and appearance before applying.

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. SB-4000 may slightly darken some surfaces. 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.

Coverage Per Gallon

Application Sq.Feet Sq.Meters
Pavers & Other Hardscape Surfaces 75 – 200 6.9 – 18.6
Concrete 100 – 200 9.3 – 18.6
Retaining Walls & Other Vertical Surfaces 50 – 200 4.6 – 18.6

Coverage based on two coats applied wet-on-wet. Use 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.
