Sealing a concrete walkway
Q. I need to seal my stamped concrete walkway. What sealer should I use?
A. There are two types of concrete sealers: topical and penetrating. If the concrete walkway has not been sealed before, it is a good candidate for a penetrating sealer.
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.
You should be able to find concrete sealers in building-supply houses. Read the manufacturer’s instructions before buying the product to be sure that you understand when is the best time, and how, to apply it, and how long it takes for the sealer to dry.
