Products for concrete and masonry


SB2418 High Gloss Masonry Sealer

SB 2418 High Gloss Masonry Sealer is a high quality waterborne cross-linking water repellent and sealer based on acrylic resin technology. It dries to a glossy film which will protect the surface from salt intrusion, water, soda, alcohol, motor oil, dirt, and tannins. This product is UV resistant and has been shown to prevent efflorescence in masonry surfaces, while remaining flexible. SB 2418 also has superb mar and scuff resistance for extended protection on old or new concrete.


For sealing or resealing cured concrete it is strongly suggested to thoroughly clean the surface with a quality cleaner like SB 2790 Con-D-Soil and pressure washing to remove any dirt, stains, or loose sealer. Allow to dry completely before applying SB 2418. SB 2418 is normally applied b low pressure, garden-type pump sprayer followed by back-rolling. It can also be applied by roller, brush or squeegee depending on texture and shape of the substrate. Rough textured placements will require a heavier application rate. Topical sealers should all include a final brushing or rolling to the final coat for eliminating drips and heavy application spots.

Dilution and Coverage

Dilution: Product used undiluted for most applications — test application recommended.

Coverage: Dependent upon substrate and other conditions.


Before application, substrate must be completely dry. SB 2418 should be applied at a rate of 150 – 300 square feet per gallon depending on surface texture and desired gloss. In most situations 2 thin coats will provide a more even surface than one heavy coat where the product “ponds” in low places. For application on very porous surfaces it is recommended to apply initial coat very thin [even adding water if necessary] to allow any foam/bubbles to break for a smooth, even cure. Once dry, a second coat can be applied if desired.

Cleanup of tools or equipment can be done with warm soap and water. Dried or partially dried films may require a solvent such as alcohol, acetone, or a glycol ether to remove. Special cleaners for removing latex paints from brushes are available and quite suitable. Mineral spirits is not effective. Drying time is dependent on the ambient temperature and relative humidity. In warm, dry weather allow at least 3-4 hours for light foot traffic and 24 hours for vehicular traffic.
