SB-4000 Water Repellent & Salt Blocker
Invisible Penetrating Sealer
- Chemically Bonded Protection: Surface Penetrating, Long Lasting & Durable
- Silane/Siloxane Water-Based Blend: Repels Water, Protects Surface from Salt Attack, Non-Hazardous and VOC/EPA Compliant
- Non-Film Forming with Transparent Finish: Does Not Alter the Appearance of Most Surfaces
- 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 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
|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.

SB-4000 Helpful Information
TEST SEALER FIRST on a small inconspicuous area to determine suitability and if desired results are achievable with this product. Over application on some very dense substrates may slightly darken the surface or leave a white haze. On new concrete, SB-4000 should be applied once it is fully cured (30 days after installation). Before sealing, surface should be thoroughly cleaned and prepared with Surebond Cleaners. For spot cleaning, use S.R.B. and/or Oil Extractor before cleaning the surface overall with SureClean. Use Efflo Off for efflorescence cleaning and SureStrip to remove previously applied sealer or curing compounds, other than SB-4000. Thoroughly rinse all cleaner residue from the surface. If installing joint sand/polymeric sand, install on a dry surface prior to sealing following manufacturer’s instructions. Allow surface to dry for a minimum of 2 hours after cleaning, polymeric sand activation and/or rain before sealer application.
Prior to sealing: Use a leaf blower to remove dust, debris and fine sand particles from the surface. Cover/protect nearby landscape, vehicles, window glass and buildings from overspray during application.
Apply when day and night temperatures are between 40°F – 95°F. Maximum surface temperature should not exceed 120°F. Allow surface to dry for a minimum of 2 hours after cleaning and/or rain before sealer application. Avoid windy conditions to keep sealer spray from drifting. NO pre-blending or mixing required. DO NOT DILUTE. Agitate or stir before each use. Always apply two coats of SB-4000 to ensure complete coverage. On large projects, it may be necessary to work in smaller more manageable sections.
Application Tools: low pressure high volume sprayer, slit foam roller
Spray & Back Roll Application (Wet on Wet): Agitate or stir before each use. Use coverage rate for your specific surface. Hold sprayer nozzle perpendicular to the surface, spray and overlap each spray pass. Apply a second coat while the first coat is still wet (“wet on wet”) and at a right angle to the first application. Do not allow surface to dry between coats. Use liberally but do not allow sealer to puddle. Before second coat dries, back-roll surface with a foam roller to eliminate any pooling and to even out the sealer. Avoid contact with glass. If this product is allowed to dry on glass a residue may be created that is not removable. If accidentally splashed on glass, flush immediately with water.
Re-applications may need to be carried out every 5 – 7 years depending on environmental conditions such as weather and volume of traffic.

Should a problem occur with this product, SEK-Surebond limits liability to product replacement only. Buyer assumes all risk and liability resulting from the use or misuse of this product.
Surface will be dry to the touch within approximately 60 minutes assuming 65-85°F at 50% relative humidity. Low surface or air temperature and or high relative humidity will extend dry times. Area is rain safe and can be open to foot & vehicular traffic in 2 – 4 hours depending on weather and site conditions. Protect the surface from dust, rain, condensation and traffic while drying.
For tools and equipment, clean with soap and water before product is allowed to dry.
