When it comes to painting, nothing is more frustrating than little mistakes that aren’t noticed until after the job is done. And, in the case of paint bubbling, sometimes the flaws don’t show up until the paint is completely dry! There is a way to avoid such unpleasant surprises. Following our tips below can help you avoid some common painting mistakes and fix paint bubbling on walls.

Why does paint bubble?

Often, paint bubbles on walls from moisture or heat, causing a layer—or several layers—to peel away from the surface below. Other reasons your paint may not bond properly to the surface you’re painting include:

Remnants on the wall.
Paint has a hard time sticking to surfaces that are hot, dirty, or not completely dry. Keep an eye out for water damage, mold and mildew.

damp walls.
If you’re working in high humidity or in an area of the home that’s prone to damp walls, such as a bathroom or basement, the moisture makes it harder for paint to adhere.

Air in the paint.
Whether by shaking the can or rolling the paint too fast, introducing air bubbles into the paint increases the likelihood of blistering.

Working with the wrong tools.
When you paint over a textured surface, using a special brush or roller can help. And when you paint over existing paint, try to match types. Oil-based paint tends to bubble when poured over latex.

Skipping Primer.
If you don’t prepare your wall properly, there is a high chance of bubbles forming when the paint dries. Cleaning your wall and using a primer both help reduce blistering.

how to prevent paint bubbles

Preventing paint bubbles means taking care of the issues that cause bubbling before you start painting. Here’s how to prepare your home for interior painting:

clean things up.
For medium to light soiling, simply wipe down the walls you want to paint with a damp towel or sponge and some warm water. For extra cleaning power, add soap to the hot water. Just make sure you go over them again with a damp towel to remove any soap residue. There are even more tips for getting everything spotless in our guide to cleaning walls.

Dry it.
Avoid paint bubbles from moisture on the wall by taking care of damp walls before breaking out the brushes and rollers. Allow your wall to dry completely before painting. Open windows and doors to increase airflow, or run a dehumidifier and turn on a few fans to dry things out.

Keep an eye on the weather.
Do not act contrary to nature. If you can, plan to paint on days that aren’t hot or humid, so your paint can dry more evenly. Or you can make sure your heating or cooling is running at a comfortable temperature and turn on a dehumidifier.

Don’t rush when you’re painting.
slow and steady is the key. Try not to paint too fast on the walls, or you may wind up. Even better, call Raptorspainting for painting company toronto! If you paint yourself, make sure each layer is dry before starting on the next.

Match paint type.
Latex and oil paint don’t mix well, so prime over your old paint or be sure to use the same paint type that’s already there.

Prime before painting.
Some people try to skip primer, but it’s essential for getting the best, most even paint job. Make sure you know the ins and outs of a primer before you get started.

Avoid blistering exterior paint.
If you’re painting the exterior of your home, follow the same tips as you would for interior painting. Be especially sure to avoid rainy or very hot days.
