When your walls are facing issues such as dampness, blistering, or peeling, don’t rush to call a technician. Try the following methods, which can help you resolve the problem quickly.

After several years of use, the walls in your home may start to develop mold, blister, or peel. During the rainy season, this issue can become even more severe. Moldy walls not only affect the appearance but also pose a health risk to your family. To address this situation, most people would call a professional. However, with the following methods, you can quickly and effectively handle peeling or moldy walls on your own without the need for a professional, helping you save money for your family.

1.   Mold treatment method

Step 1:   When mold appears on the walls, use a dry toothbrush to brush off the mold spots first. Then, use a soft cloth soaked in alcohol to gently wipe the wall, which helps dry it out and prevent further mold growth.

Step 2:   Mix bleach and water in a ratio of 1:99, pour the solution into a spray bottle, and spray it on the moldy wall. This will clean the mold easily. In humid weather, you can mix bleach and water in a 1:20 ratio and apply it to the moldy areas. After the wall dries, use sandpaper to smooth the surface, then apply a layer of waterproof primer before painting the wall. Doing this will help prevent moisture from causing further mold growth.

2.   What to do if the wall blisters?

Blistering walls are also a common issue in home decoration, caused by various reasons. When the wall blisters, follow these steps:

Step 1:   Remove the blistered and peeling areas. If it’s caused by the wall filler, remove the old filler and apply a high-quality wall filler to patch it up.

Step 2:   For localized blisters, scrape off only the affected area, smooth the edges, then apply primer and repaint. If the blister covers a large area, scrape it all off, wait for the wall to fully dry, and then apply a new layer of plaster.

Step 3:   During the decorating process, follow proper construction guidelines, apply waterproofing at the base of the walls, and repair any cracks.

Step 4:   Avoid painting during the rainy season. It's recommended to use the same brand and product line of primer and paint for the best results.

What to do if the wall is peeling?

Peeling walls not only affect appearance but also create dust and sanitation issues. Generally, when addressing peeling, it’s best to handle it appropriately based on the specific situation.

Step 1:   Remove the peeling areas and scrape off the old filler. Smooth the edges of the scraped area, then apply primer. The top layer of paint can be applied over the primer.

Step 2:   If the peeling is severe, remove the wall layer and repaint with a surface treatment or primer.

Step 3:   For areas with heavy peeling, dampen the affected section by spraying water, then use a scraper to remove the peeling paint. If no dust falls off, it means the original wall filler is of good quality. You can smooth the area with fine sandpaper and then apply primer and paint as needed.
