The use of concrete sealers in concrete waterproofing is the most common and effective way of protecting your concrete from the destructive elements. There are two types of concrete sealers. These are:
- Penetrating sealers
- Film-forming sealers
Penetrating sealers are also known as impregnating sealers because they penetrate concrete and bond with its chemical composition to form a barrier that blocks out moisture. It is a little expensive but its effect on concrete lasts much longer. It may take you an eternity before you make another trip to the dealer. Plus, the appearance of your concrete remains unaltered after applying a penetrating sealer. This is a great option for a concrete basement.
Film-forming sealers, on the other hand, give your concrete a glossy finish. However, you need to apply it frequently because it wears out faster. Whether you opt to use the penetrating or film-forming sealer, be sure to apply it on a clean and dry concrete for better results. Additionally, never apply concrete sealers on immature concrete. By immature I mean new concrete that is still under the curing process. Give it ample time to cure fully before you do concrete waterproofing. At least a month should be enough.
