Painting Defects Every Painter Needs To Look Out For

Painting can give a classic appearance to a wall, piece of furniture, or any other structure. It also offers protection against weathering, decaying, and corrosion. Unfortunately, these agents can affect paint films, depending on the skill of the painter, type of surface, and other factors. To prevent them from occurring, you need to understand the painting defects. That’s the only way you’ll be perfect like Maximilian Lang-Orsini.

Here are some defects you need to know about:

  1. Blistering And Peeling

These defects usually occur when a paint film swells. This swelling may be caused by an air bubble that forms under the film or because of oil, moisture, and grease matter. The swelling caused by moisture is referred to as peeling, while that caused by grease matter and oil is called blistering.

These defects happen when you use excess oil in the final coat, season timber imperfectly, and imprison gases between the paint coats. You can eliminate them by using porous paints such as emulsion paints. Avoiding non-porous paints like enamel and oil paints can also reduce their occurrence.

  1. Wrinkling

This type of defect happens when a thick paint layer coats a surface. When this happens, the paint film shrinks and forms a crawl. If you want to prevent it from tainting your good work, allow the undercoat to dry properly before applying the final coat. This defect can illustrate how less-skilled a painter you are. If you want to keep your job, you better look out for it.

  1. Fading

Fading refers to the discoloration of a painted surface. It’s mainly caused by atmospheric agencies like moisture, sunlight, and other environmental factors. The only way to prevent it from happening is to use paints with weather-resistant pigments. You’re likely to face this defect when painting exterior walls and roofs because they’re exposed to these agents.

  1. Running

Running happens when a thin paint layer coats a smooth and glossy surface. Often, this paint may run back and leave some surface areas uncovered. Waiting for the paint coats to dry before applying another one can prevent this defect from occurring.

  1. Greening

Greening is a defect that occurs when that paint film isn’t opaque enough to cover a surface. You may easily differentiate the painting layers where there’s this defect. To counter it, use a paint that has sufficient opacity. That way, you’ll ensure the last paint layer is perfect without greening patches.

  1. Chalking

Chalking happens when powder forms on a painted surface. It may result due to using insufficient oil in a primer. Combating this defect is easy because it only requires you to use enough oil in the primer. You also want to ensure that you apply the paint according to the recommended spreading rate.

  1. Sagging

If you’re painting a surface with a thick paint layer, the film may run downwards and sag. Sagging is similar to running, though the paint in sagging is thicker than running. Spreading the paint evenly using the recommended rate may prevent it from happening.

The Bottom Line

Painting defects can taint the appearance of a masterpiece. Therefore, you need to know how they occur and how to prevent them if you want to produce perfect results consistently.
