My concrete driveway is pitted and needs some kind of sealant, but I’m not sure what to use? -Bill
It can be a little confusing if you’ve never had to deal with sealing concrete. Basically, there are four types of concrete sealers available:
In your case, I would probably recommend a penetrating sealer, since it’s easier to apply and provides excellent protection in outdoor exposure conditions such as a driveway.
Most products are breathable, allowing moisture to escape, and will also provide protection without changing the surface appearance or leaving a sheen.
Since your driveway is pitted, you might also want to consider resurfacing the concrete before sealing it.
Good luck with your project,
