Do You Know Why Paint Crack, Bubble Or Peel?

If you have ever tried to paint your own home or hired a naïve , then you must be aware of the fact that overtime paint crack, bubble or peel. Sometimes these problems become evident very soon while sometimes after a few months to start to notice cracking and peeling of paint.

But, have you ever thought that why such type of problems occur? Why sometimes these problems become evident really fast while sometimes they take time to appear on surface? In this blog post we will discuss some of the popular reasons that why these problems occur.

Why does paint crack?

Painters use a wide terminology to describe the common paint cracks. Some of the most common cracks and causes include:
Alligator cracks: Paint was applied on a wet basecoat or a glossy finish, a stiff coating like an oil-based enamel was applied on something with a higher expansion rate like plaster.
Hairline cracks: Paint was poor-quality and has low adhesion and flexibility; paint was over-spread.
Mud cracks: Surface was dirty; too thick paint was applied

Why does paint bubble?

This is a very common home paint problem. The freshly applied coat of paint starts looking like a uneven surface of the moon. Impatience is probably the issue. Shaking can bring in excess air. Also, rolling too vigorously can introduce bubbles into the paint. High-gloss paints are especially very sensitive, so it is important that you slow down and paint with patience.
Another troublemaker is a porous surface like brick, plywood or sheetrock. A primer or sealant can help.
In case of big bubbles, blisters are generally seen on acrylic and latex interior and exterior finishes. They introduce themselves when the paint gets detached from its base. This problem usually takes place when the paint is applied in a very cold or hot weather or the surface was damp.
Paints don’t work well during extreme weather. Painting during a humid evening generally leads to bulging blisters, shouts of frustration and several other problems. Painting during hot, sunny afternoon may cause the upper layer of the paint to dry too quickly, making the solvents vaporize and expand into hideous boils.

Why does paint peel?

In simple words, paint peel because it can’t stick to the base or surface.
The easiest solution is to sand. Sandpaper roughens the base surface, creating small peaks and valleys onto which paint molecules can stick.
Paint peeling is usually a result of high-humidity or surface moisture. Chemical incompatibility is another problem. You can apply oil-based paints on galvanized metal for hours, but it won’t stick.The fact is, working with paints can be really troublesome. That is where Repaint Pro can help.
