Sealing a concrete driveway
Q. Please provide advice for sealing our 2-year-old concrete driveway to prevent deterioration. So far there are only a few small spalls and no cracks.
A. There are two kinds of concrete sealers: penetrating and topical.
Penetrating sealers are the best and are permanent, but they only work if the concrete is absorbent. To check if the concrete is absorbent, sprinkle water on it. If the water soaks in, you can use a penetrating sealer, but if the water beads, it would be a waste of time and money.
Topical sealers can be applied on any clean concrete, but need to be reapplied regularly – every one to three years, depending on use.by
