Dust, dirt, and grime coating the walls act as a barrier separating the paint from the walls.
While it may look good immediately after painting, the paint will soon fail and begin to bubble.
Solution: Clean the Walls Before Painting
Clean the walls thoroughly before painting.
Vacuum off any dust and dry debris andscrub away any grime with a damp towelor sponge.
Wipe away any moisture with a dry towel and allow the walls to air dry.
You Used the Wrong Paint

You Mixed Paint Types
Repainting your walls?
Be sure to choose the right new paint to cover the old paint.
In most cases of over-mixing, the paint will adhere properly but have a poor appearance.
Solution: Carefully Mix Paint
Mix your paint slowly using a wooden stir stick.
It’s better to take your time mixing it than to introduce air bubbles by mixing too rapidly.
Excessive Heat
Even a quality paint job can bubble if the walls are exposed to excess heat.
Solution: Prevent Excessive Heat
Keep flames and hot appliances away from painted surfaces.
If possible, prevent prolonged direct sun exposure or opt for UV-resistant paint.
This is because the paint will stick to the contamination on the wall, but not the wall itself.
You Skipped Primer
Some surfaces must be primed before you’ve got the option to paint.
Skipping priming and painting the bare wood will result in poor adhesion and eventual bubbling.
Solution: Prime the Surface Before Painting
Use a bonding primer to promote better paint adhesion.
Typically, you’ll find an ideal temperature and humidity range for painting.
Instead, leave them on for several days afterward toallow the paint to fully drywithout excess moisture exposure.
