How to Repaint Basement Walls That Have Been Painted Before
Painting basement walls that have already been painted is similar to painting any other walls. If your basement has been painted, the concrete walls have most likely been acid etched, primed or sealed and then painted. The only thing left to do is touch it up and add one or two coats of paint. This project requires simple painting skills.

Order your paint. Calculate how much paint you will need by measuring the height and width of each wall with a tape measure and multiplying the two measurements with a calculator to get the square footage. Add the square footage of all the walls together and divide by 400, because a gallon of paint covers 400 square feet. You will have the number of gallons you need.

Move furniture and other objects away from the walls. Spread protective drop cloths over the floor and apply painter's tape to the windowsills and doorways if necessary.

Remove peeling paint with a paint scraper or rough sandpaper and wipe away residual sanding dust. Clean away grime and grease with soap and water. Allow walls to dry completely.

Apply paint using a roller for maximum coverage or a brush if you do not have a roller. A power roller, which uses an electric pump to feed paint to the roller, is also an option. Apply thick coats, but not so thick that the paint splatters or drips.

Allow the first coat of paint to dry completely. This may take four to 12 hours. Add a second coat of paint if necessary.
