Take Care of Your Concrete

Once you have made the investment of new concrete it is important that you protect it by applying a sealer. TK-290 TRI-SILOXANE can be used to protect and seal any clean and dry cementitious surface, above ground vertical and horizontal. It protects the surface against damaging effects of water intrusion, acid rain, deicing chemicals, freeze/thaw exposure, airborne dirt, smog, industrial fumes, and most other atmospheric chemicals. The most common winter damage to concrete paving is scaling, which is caused by repeated cycles of freezing and thawing in the presence of de-icers, road salts and moisture. Water is absorbed into the very fine capillary spaces and hairline cracks in concrete. When the water freezes it expands 9% in volume. This expansion can physically break the concrete bonds & cause it to flake, pit, spall and crack. Sealing the concrete reduces the amount of water absorption. We have TK 290 Sealer and TK Bright Kure & Seal in stock to assist you in protecting your investment.
