Water Repellent & Salt Blocker Invisible Penetrating Sealer
SB-4000 Water Repellent & Salt Blocker Invisible Penetrating Sealer is a penetrating, breathable silane/siloxane blend, water based, low VOC sealer that protects horizontal and vertical surfaces from water penetration and chloride salt damage from the use of de-icers or exposure to salt air. SB-4000 has the consistency of water and is milky white in appearance when applied and dries clear with an invisible finish. Some surfaces may darken slightly. SB-4000 is not hazardous and exceeds all VOC and EPA standards. It can be used indoors and outdoors on both new and old surfaces. SB-4000 can be applied immediately, as its unmatched breathability will not trap efflorescence. On new concrete, SB-4000 should be applied once concrete is fully cured (30 days after installation). SB-4000 requires two coats. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (82°C).
Ideal for horizontal and vertical surfaces including concrete, concrete and clay pavers, grout, unglazed tile and terra cotta. Suitable for cultured and natural stone containing quartz or other silicas. Not recommended for granite, marble, limestone, slate, agglomerate tiles and surfaces with a high gloss finish as they do not absorb the sealer.
|Pavers & Other Hardscape Surfaces||75 – 200||6.9 – 18.6|

|Retaining Walls & Other Vertical Surfaces||50 – 200||4.6 – 18.6|
Note: Two coats applied wet-on-wet at right angles to first coat. 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.
