SB-6400 Wet Look
Hybrid Sealer

  • Surface Enhancement: Deeply Enhances Surface Tone with Matte Finish
  • Chemically Bonded Protection: Surface Penetrating, Long Lasting & Durable
  • Silane/Siloxane Water-Based Resin Blend: Repels Water, Protects Surface from Salt Attack, Non-Hazardous and VOC/EPA Compliant
  • Breathable, Immediate Application: Does Not Trap Moisture or Efflorescence

SB-6400 Wet Look Hybrid Sealer is a unique water-based hybrid blend of silane/siloxane and proprietary polymers that chemically bond to the surface and repel both water and oil.  It can be used indoors and outdoors, on old and new, horizontal or vertical surfaces. SB-6400 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-6400 should be applied once concrete is fully cured (30 days after installation). SB-6400 will seal and enhance the beauty of new and old surfaces by enriching/darkening surface tone and color contrast with a natural looking matte finish. SB-6400 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-6400 helps to reduce biological growth such as mold, moss and algae. It is non-hazardous and VOC/EPA compliant. SB-6400 has the consistency of water, is milky white when applied and dries transparent with matte finish. 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 natural and manufactured stone containing quartz or other silicas. Can also be used on concrete and clay pavers, flat and stamped concrete, masonry, segmental retaining wall blocks, concrete walls, exposed aggregate, 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, limestone, slate, agglomerate tiles, glazed or ceramic tile. Due to the inherent variability of natural stone and clay products, performance may vary. 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. 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
Natural Stone & Clay Pavers 200 – 400 18.6 – 37.1
High Density Concrete & Pavers 200 – 400 18.6 – 37.1
Low Density Concrete & Pavers 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-6400 Helpful Information

SB-6400 TDS Spanish


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 leave a white haze. On new concrete, SB-6400 should be applied once concrete 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, other than SB-6400. 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-6400 to ensure complete coverage.

Application Tools:  low pressure high volume sprayer, slit foam roller

Spray & Back Roll Application (Wet on Wet):  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. Excess sealer left on the surface can be slippery, cures slowly and is difficult to remove once cured.  On large projects, it may be necessary to work in manageable sections. 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.

SB-6400 is a two application product. SB-6400 re-application may need to be carried out every 5 – 7 years depending on the type of surface and environmental/site conditions. To maintain the desired level of enhancement, a light coat may need to be re-applied after 1 – 3 years depending on the type of surface and environmental/site conditions.

NOTE: Excessive applications can cause surface to become slippery. Application of this product is out of the control of SEK-Surebond. Application steps should be followed completely and accurately. 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.

Dry Time

Surface will be dry to the touch within 60 minutes assuming 65-85°F at 50% relative humidity. Low surface or air temperature and or high relative humidity will extend dry times. Protect the surface from dust, rain, condensation and traffic while drying. Area can be open to foot & vehicular traffic in 24 hours depending on site conditions. Full cure in 5 days under normal conditions.

Clean Up

For tools and equipment, clean with soap and water before product is allowed to dry.
