Whether your patio is plain concrete, colored concrete, stamped concrete, or exposed aggregate, sealing after the slab has cured, as well as every few years after, is recommended as part of the maintenance plan. A sealed concrete patio will have a rich color and, if desired, a glossy sheen . You can even select a tinted sealer that will further enhance the color of your patio. For colored patios, a sealer will also help prevent efflorescence, which is a white powdery residue that can form on the surface. Slip resistant sealers are also available and are great for using on patios near outdoor cooking areas, where sprinklers may get the concrete wet or in humid climates.
Stain protection can also be achieved by sealing your concrete. In the great outdoors, there are a number of things that can leave unsightly stains on the surface of your patio – leaves, dirt, fertilizer, pet urine, oil, spilled drinks and much more. The right concrete and masonry sealers will keep all of the above from penetrating the surface of the concrete and leaving an unsightly stain.
Sealing your concrete patio will reduce the chance of freeze thaw damage to the surface of the concrete. Freeze thaw damage can cause cracks or surface flaking, which is caused by water penetrating the surface of the concrete and then expanding as it freezes. A sealer will keep water from sinking into the patio and creating this damage. You know your sealer is working because water will bead on the surface. When this no longer happens it is time to reseal your patio. High traffic areas of your patio may need resealing on a frequent basis.
