Concrete sealer

Concrete sealer is like a special jacket for your driveway or patio made out of a clear liquid. When you pour or spray it onto the surface, it soaks into the tiny holes in the concrete and makes a protective coating that helps keep the concrete looking new and clean. The sealer keeps water, oil, and other yucky stuff from getting inside the concrete and staining it. Think of it like putting on sunscreen so you don't get sunburned - the sealer helps protect the concrete from damage.
