Sealing concrete is a vital step in ensuring that any concrete surface is protected from environmental conditions, chemicals, spills, and stains. For concrete located outdoors, like driveways, freezing and thawing can damage the surface. Oil, salt, and other chemicals, like fertilizer, can be spilled onto outdoor concrete. Concrete is porous, and these spills can easily penetrate into the surface, causing stains that cannot be removed. For concrete located indoors, such as countertops, the sealer protects the surface from scratches and other damage, as well as from food and drink spills.
When sealing concrete, the first step is always surface preparation. Make sure that the countertop is clean and free from dirt, grime, oil, and any other substance that may affect the adhesion of the sealer to the concrete surface. If there is a previous sealer, a lot of manufacturers recommend removing the old sealer prior to the installation of the new one.
Once the surface is ready, the sealer can be applied. This sealer usually is applied using a roller or sprayer to make sure that the coating is even. The type of sealer you use will determine the right application technique, so it is important to check the manufacturer
