Bubbling or crumbling of wall paint can be caused by multiple factors. Poor preparation of the surface at the time of painting, using low-quality paint or improper applications are some of the major causes. If you live in a considerably old home, you might have painted your walls many times, resulting in an accumulation of thick layers of paint. When affected by moisture, these layers can separate and crumble. Whatever the cause of the crumbling, you will have to follow a few steps before repainting the wall to prevent frequent bubbling of the paint. The procedure below will help you.

Prep the Wall

While adding new paint on the bubbled paint might seem practical, it is a temporary fix. Therefore, you want to start by getting rid of the crumbled, loose or peeling paint. You will need a putty knife for this to scrape, gouge, or score the old paint. However, you must be gentle to prevent unnecessary gouging of your wall. With all the damaged paint cleaned out, you can sand the area slightly to remove any remaining bits of bubbling paint. Once you are done, rinse a piece of cloth in water, and use it to wipe away the dust and other debris.

Cleaning and allowing your wall to dry is essential. If you skip these steps, your new paint won't stick to the surface of the wall properly, meaning it will peel with time.

Resurface the Wall

Scrapping and gouging the paint will leave some uneven surfaces on the wall. To resurface the wall, you will need a filler material or wall putty. Using the putty knife, carefully apply thin layers of the filler or putty to the cleaned out wall area. Consider extending your patch beyond the bubbled paint section to allow your new paint to blend well into the rest of your wall. Once you apply your putty or filler material, allow it to dry according to the manufacturer's instructions.

Sand and Repaint the Wall

When the putty or filler material has dried completely, you will have to sand the area thoroughly to make it even. If you can still feel some dips and humps after sanding, add another layer of filler material or putty and sand again once the material is dried. Sanding should make the previously damaged area and the rest of your wall even. You will then have to apply your primer, and let it dry. Next, use a roller to gently apply a coat of interior paint to your wall, and add a second coat once it dries.
