Basement Sealers: For concrete blocks or cinderblock walls use a silane/siloxane sealer. For poured foundations or concrete slabs use a silicate/siliconate sealer to densify and waterproof.
Driveway Sealers: Use a silane/siloxane sealer if you live in a colder climate with a lot of snow and ice. For a warmer climate you can use a water based acrylic formulation.
Patio Sealers: Use a decorative acrylic sealer either solvent based or water based. Solvent based sealers will not be VOC compliant in all 50 states but they will leave a high gloss shine. Water based sealers leave a matte finish but have no harsh, solvent odors.
Warehouse Sealers: If the concrete will be polished use a concrete densifier; either a sodium silicate or a lithium silicate. If you are looking for chemical or abrasion resistance use an aliphatic urethane.
Garage Sealers/Shop Floors: If you are looking for a natural garage floor use a siliate/siliconate blend. If you are looking for a decorative finish or for added chemical/abrasion resistance use an epoxy coating followed by an aliphatic urethane topcoat.
Countertop Sealers: Use a concentrated penetrating acrylic sealer that you work into the concrete. Use in conjunction with a concrete wax for added protection and shine.
Our Take: Our go to manufacturers of concrete sealers include Kretetek, Prosoco, Scofield and ChemMasters.
