Tips for Preventing Paint Bubbling on Your Walls

By May 31, 2023 No Comments



A freshly painted room looks bright and lively, making a home feel new. But experiencing paint bubbles during the painting process or after can quickly ruin this wonderful experience. Paint bubbling, also known as paint blisters, can occur for various reasons. These bubbles can lead to cracking, peeling, and other unsightly effects if left unattended.

Here is everything you need to know about paint bubbling and provide tips on how to prevent paint bubbling on your walls.

Reduce moisture before painting.

One major cause of paint bubbles is moisture or dampness on the walls. The paint will not settle correctly in a damp environment, and this can cause bubbles to form. To prevent this:
-Make sure the walls are dry before painting.
-Check the weather forecast to ensure dry weather and use fans to circulate air.
-If you notice excessively damp areas, use a dehumidifier to dry them out.

Proper surface preparation

Paint bubbles can also be caused by poor surface preparation. Before painting, ensure the walls are clean, dry, and free of any substances interfering with a proper bond. This includes peeling paint, dirt, and debris. You can achieve this by washing walls with mild soapy water and a sponge. Allow the walls to dry thoroughly, then gently sand with fine-grit sandpaper to create an ideal surface for bonding.

Use high-quality paint

Some paint brands need to be improved and are prone to paint bubbling. It is essential to choose high-quality paint. High-quality paint guarantees excellent adhesion, durability, and resistance to weather conditions, including moisture. Cheap paints do not adhere correctly, leading to paint bubbles. Spend a bit extra on high-quality paint, and you will avoid future problems.

Apply paint correctly

One of the reasons paint bubbles occur is due to an incorrect painting technique. When applied too thick, paint can develop air pockets, leading to paint bubbles. A thinner coat of paint is better when painting, and it is best to mix the paint adequately before application. Do not shake the paint; stir it slowly to avoid introducing air bubbles that can cause blisters.

Allow enough time for each coat of paint to dry.

Another common reason for paint bubbles is painting overcoats without enough time to dry. When you paint over a still-drying coat, you can trap the solvents, leading to air bubbles. Therefore, allowing enough time for each coat to dry is essential before adding another layer of paint. Consult the paint manufacturer’s instructions for drying times between coats.


Preventing paint bubbles is all about proper preparation and technique. Before painting, ensure the walls are clean, dry, and free from any imperfections that could cause bubbles. Then, use high-quality paint, apply it correctly, and give each coat of paint enough time to dry before applying another. Following these tips will avoid paint bubbling and enjoy a smooth, beautiful finish for years.
