Had a new concrete driveway installed or resurfaced? Congratulations! It is quite exciting but then also quite worrisome knowing that it could acquire damage anytime. A driveway is exposed to a variety of damaging elements. This is one major reason why almost every concrete contractor recommends having it sealed. Concrete sealing provides several benefits that homeowners should take advantage of.
Concrete sealers come in a variety of finishes. There are flat or matte types and then there are high-gloss sealers, depending on how much sheen you want on your driveway. If you had a driveway resurfacing done, like concrete staining, the sealer can help enhance the color. A good coating should last a couple of years, depending on how much vehicular or foot traffic the driveway gets. Once it looks faded or dull, it is highly recommended to seal it again with the same type of sealer used the first time.
Sealing helps close the pores of concrete, thus, keeping it from absorbing moisture that could weaken the slab. One common reason for concrete damage is the freeze-thaw damage. This is when water gets absorbed into the concrete, freezes in cold weather and then thaws in warmer temperature. This continuous expansion of water molecules causes concrete to break and weaken. Sealers keep water out, thus, preventing freeze-thaw damage.
There are many liquids that could stain a concrete surface. Red wine, chemicals, and even some falling fruits could discolor concrete, making it an eyesore. Sealing it can help prevent this from happening. Stains often occur when pigments are absorbed into the many pores of the concrete slab. Because it is lodged deep into very small holes and crevices, cleaning it can’t take it all out. If pores are sealed, the liquid stays on the surface.
A layer of sealer on top of a concrete driveway makes it easier to clean and maintain. Because it seals off pores, it keeps dirt, dust, water, and liquids at the surface, making it easier to sweep or wipe off. Owners don’t have to worry about pressure washing their driveways because water won’t get absorbed deep into the slab. Sealers also help minimize the damaging effects of deicing salts on concrete. If you are planning to use a specific cleaner, consult the installer first to make sure it won’t do more harm than good.
