What Is Crazing in Painting?

The crazing is due to the top layer of the painting drying faster than the bottom layer. The top layer forms a skin and hardens whilst stretching but the underlay is still wet and trying to dry. The top layer literally cracks through this stress.

What Is Crazing in Painting?

Crazing is a type of paint failure in which cracks form in the paint film, usually due to age or exposure to weather. It is most commonly seen on painted wood surfaces, such as doors and window frames.

Crazing can also occur on other painted surfaces, such as walls and ceilings. Crazing is caused by the paint shrinking as it dries. This causes the paint to pull away from the surface it is painted on, creating small cracks.

Crazing is more likely to occur on surfaces that are not properly prepared before painting, such as bare wood or metal.

It is also more likely to occur in paint films that are not properly protected from the elements, such as UV light and moisture.

Crazing can be prevented by using a highquality primer and paint, and by ensuring that the surface is properly prepared before painting. If crazing does occur, it can be repaired by sanding down the affected area and repainting.
