Blistering in Paint Coatings

Blistering is a problem with paint coatings. It shows up as bubbles or bumps on the painted surface. This usually means something is wrong with the coating. Blistering can happen on steel things, like pipelines and tanks and even on the paint in your home.
If you do not fix blistering away it can cause a lot of trouble. The coating can break down. That can lead to corrosion and expensive repairs.

What is Blistering?

Blistering is when bubbles form under the paint. This happens when water, air or bad things get stuck under the coating and make pressure. The pressure makes the coating lift off the surface.

Common Causes of Blistering

1. Water Gets Trapped

If you paint on a surface or it is too humid water can get stuck under the coating.

2. The Surface is Dirty

If there is oil, grease or dirt on the surface before you paint it can make the paint not stick well and cause blisters.

3. The Surface is Not Ready

If you do not clean the surface enough the paint will not stick to it.

4. Much Paint

If you put on too much paint it can trap bad things inside the coating.

5. It Gets Too Hot

If it gets too hot it can make the air or water under the coating expand and cause pressure.
