Do you plan on painting your basement? It’s important you consider the problems that people encounter when painting basements. One such problem is peeling paint.
There are various reasons why paint peels off basement walls. The following are the most common causes and solutions.
High Levels of Humidity
High humidity levels in the basement will not only result in the growth of mold but will also encourage the peeling of the wall paint. This is because sealers and paints used on basement walls are often porous. The paints therefore absorb the moisture from the air. The water is then also absorbed into the wall.
When water is absorbed into the wall, it dissolves minerals present in the masonry. This results in the leaching of the minerals out of the masonry. Efflorescence is formed on the surface of the wall. The forcing out of and crystallization of the minerals pushes the paint from the surface of the wall. The paint therefore peels off the walls.
Solution: This problem can be solved by addressing the sources of humidity in the basement. You may need to invest in waterproofing if there are cracks or other issues causing water seepage. A dehumidifier will also go a long way in reducing the humidity level in the basement.
Poor Preparation of the Surface
Paint adheres properly when the surface is dry and clean. If there are particles of dust on the wall, the paint is likely to peel off when it dries. The same thing happens when you paint over a wet surface.
Solution: Take your time and prepare the surface of the walls carefully. Wipe down walls with a clean damp rag to ensure that there is no dust on the surface. Allow the walls to dry completely before you begin painting. This will give you the best finish.
Presence of Mold
According to the EPA, mold can cause paint to peel. Mold will not only feed on organic material but also take up water from surfaces.
Solution: Ensure that your home is free of mold by having it inspected for mold. If mold is found, have a professional team carry out the remediation.
Poor Quality Paint
Using the wrong paint will result in peeling. This is because the paint may not adhere to the surface. Poor quality paint will also give similar results.
Solution: It is important to choose the right paint for the job. Don’t skimp on paint because you’re doing your basement. Be sure to use paint that will give you great results for longer.
