Your house is beautiful. Your yard's pristine. Your driveway? It's kind of an eyesore. You can paint it to make it more appealing. Your moderate effort to color the flat expanse will make it the envy of your neighborhood. Painting a concrete driveway is, in some ways, simpler than painting a wall because all of your efforts are directed downward. Nobody would blame you if you can't wait to get started.
Sweep your driveway thoroughly with a bristle broom. Patch any holes or scratches with concrete filler. Allow it to dry, then sand the surface until it is smooth.
Remove oil or grease stains by mixing ¼ cup of trisodium phosphate for every gallon of warm water in a bucket. Put on protective gloves as you work this solution into the stains with a bristle brush.
Rinse the driveway with a strong stream of water from a hose. Allow the concrete to dry for two days.
Wait for a cool day to begin painting your driveway, or get started early in the morning before the sun makes the concrete hot and the paint a little more difficult to work with. You might wish to apply one coat of a concrete bonding primer to your driveway. Similar to wall primer, it will grab the forthcoming paint to the surface and can produce a better result. Still, you may wish to skip this step if you're in a hurry.
Cut in the paint around the edges of your driveway with a wide paintbrush, just as you would do with ceilings, doorways and windows on a wall. This step will make the paint application a relative breeze.
Start at the top of your driveway and apply the paint in sections of about 2 or 3 feet, working left to right and then down. Keep a "wet edge" with the paint roller, just as you would if you were painting a wall.
Wait for the paint to dry and apply a second coat, if you wish, to deepen the color. Follow the directions on the paint can before walking or driving a car over your newly painted driveway.
