Concrete Sealer

Concrete Sealer has become an essential part of any concrete finish. Sealers are used as a curing agent for new concrete and a protective barrier for existing concrete. When fresh concrete is placed, sealer is applied to the surface to trap moisture. This keeps the surface from drying or curing too quickly, because when this happens a weak bond is created between the surface and the rest of the concrete and that greatly increases the risk of scaling/cracking in the future. Sealers also protect against the elements, especially in harsher climates where there are many freeze and thaw cycles throughout the year. When water penetrates the surface and freezes, it expands and breaks apart the concrete, which results in scaling and spalling. Sealer creates a barrier that is impermeable to water and harmful chemicals. One of the biggest benefits of sealer is stain prevention. Proper application of a concrete sealer can prevent oil stains on driveways and garage floors, rust stains from aging patio furniture, or even black and green mold stains. With sealer, none of these can penetrate the surface which keeps concrete looking clean.
