Whether you are having a beautiful new concrete driveway poured or you already have one, it’s important that you protect and maintain your investment. A good sealer will keep your driveway looking great for many years, or rejuvenate an existing surface. Sealing a concrete driveway can be compared to waxing your car, wearing sunscreen or spraying Scotchgard ™ on your favorite shirt. A sealer will improve your driveway’s appearance, keep UV rays from causing it to fade and protect it from stains.
Stain protection is another benefit of sealing a concrete driveway. Your driveway will be subjected to many things in the great outdoors that can leave unsightly stains on the surface – leaves, dirt, fertilizer, pet urine, oil, tire tracks and much more. The right sealer will keep all of the above from penetrating the surface of the concrete and leaving an unsightly stain.
The third reason why you should seal your driveway is that it will reduce the change of freeze thaw damage. Freeze thaw damage can cause cracks or surface flaking and 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 driveway.
In short, a sealer will enhance and protect your new or existing driveway. When properly sealed and/or resealed the service life of concrete is greatly extended. Experts recommend using a penetrating sealer outdoors because it sinks down into the concrete and has a more nature finish. It is very important that sealers used on exterior concrete allow both air and moisture to pass through.
