The bubbling of a textured-paint application can take away from its aesthetic appeal in a room. There are some factors that can negatively affect the textured paint. The surface of the wall and the temperature of the room are just two factors that can cause textured paint to bubble.
Working with a Clean Wall
Before you begin any textured wall application be sure that you have a clean and smooth wall surface to paint. A clean, smooth surface will help prevent any future bubbling.
In order to remove the bubbles, use the blade of a small utility knife to cut a line in them. The line cut will release the air inside the bubble. Carefully press the bubble to gently force the air out through the line cut.
Another way to remove the air is to poke a small pinhole in the bubbles. Once you have poked the hole, use a warm, wet cloth to smooth the surface. Allow the area enough time to dry completely.
Reapply the textured finish to cover the area where the bubbles were once located. An area with a lot of bubbles should be scraped before you reapply the textured paint to the wall.
