How to Repair Bubbling Ceiling Paint

Locate the source of the bubbles. Check for leaky pipes, holes in the roof or for areas where condensation collects. Install moisture vents in attics. Moisture vents are used to help circulate air to reduce moisture to create a drier atmosphere. Without them, moisture collects in attics and eventually travels through drywall. Repair leaks and holes to prevent further moisture from getting through to the ceiling and install bathroom ceiling fans to pull additional moisture out of the bathroom.

Use the paint scraper to remove loose paints. Gently drag the edge of the scraper back and forth across the ceiling until all the loose paint is eliminated.

Sand the ceiling to smooth the surface. Paint spreads more evenly on a flat surface so sand away any surface scratches or any loose paint that could not be removed with the scraper. Sanding also removes any glossy surfaces that can keep paint from adhering properly.

Repair deep dents and holes with the drywall spackle. When it dries, sand it so that it is even with the rest of the ceiling. Use the tack cloth to wipe the ceiling clean from dirt and dust that can get under the paint and cause more bubbling.

Prime the ceiling with a high quality primer. It has a thicker consistency than watery, low quality brands, makes the surface more even and offers better coverage. Primers also seal porous surfaces, protecting them from moisture and future bubbles. Wait for the primer to dry before you paint over it. Refer to the manufacturer’s recommendations for drying times.

Paint the ceiling using the brush and roller. Brushes help get into small corners, such as joining walls and ceilings, while rollers quickly cover large areas. Roll the paint on the ceiling up and down, similar to the shape of a W to create an even finish.
