Painting Textured Walls With Air Bubbles

Sand the air bubbles from the wall. Use a 120 grit sand paper and lightly go over the bubbles to pop them. You can smooth them out, but if you like the textured effect, you can keep the walls uneven. You can also scrape off the air bubbles with a scraper and then, if desired, sand the surface until it is smooth.

Clean the walls with warm, soapy water to remove all the dirt and dust. Rinse the walls with a clean, wet rag.

Prime the surface with an alkyd primer using a 3/4-inch nap brush if you want to keep the textured look. Alkyd primers are less likely to damage the previous coat of textured paint. If you prefer a smooth finish and you sanded the wall until it is smooth, use regular latex primer and a 1/4- to 3/8-inch nap roller. For the edges and corners, use a high-quality 2-inch paint brush.

Paint the surface in a similar manner as you did the primer after allowing sufficient time for the primer to dry, per manufacturer label. A second coat of paint may be necessary for complete coverage.
