Hairline cracks in paint are not typically a major issue or a sign of structural damage but could be as a result of many factors such as a warm and humid climate or an improper paint job. Sometimes fine hairline cracks can occur on paint due to an early application of paint when the curing period of the substrate has not elapsed.
Homeowners living in areas where the humidity is too high often find small fine cracks in the paint since temperature changes and constant fluctuations in humidity levels tend to affect the paint. In this article, we will look at some of the most common causes of hairline cracks in paint and how to solve this problem.
Common Causes of Hairline Cracks in Paint
As the paint on your wall dries, it shrinks and small fine cracks or splits may occur if the paint’s adhesion with the existing surface is not 100 percent effective. Poor adhesion is usually caused by improper surface preparation before painting, heat or moisture. Here are some more details of the common causes of hairline cracks on paint.
How to Fix Hairline Cracks in Paint
The first step will involve analyzing the extent of the cracks in order to identify the best way to solve the problem. Begin by removing the loose and flaking paint using a scraper or a wire brush then sand the entire area to soften out the edges. Prepare this surface just like you would normally do with a new surface that you are about to paint.
Prime the surface before applying paint to improve adhesion.
Apply a fresh coat of paint and wait for it to dry off properly before adding a new layer of paint if necessary. For deeper hairline cracks, you may want to use a filler to fill up the cracks before applying a new layer of paint in the affected area. However, if an extensive area has been affected, you will need to scrape off the paint and then sand the entire area to even out the edges before applying a fresh coat of paint.
