Over time, the walls in your home may start to show signs of aging—mold, blistering, and peeling are common issues, especially during the rainy season. These problems not only make your home look unsightly but can also pose health risks. While most people immediately think of calling a professional technician, the good news is that you can handle many of these issues yourself with the right tools and techniques.
In this guide, we’ll share practical DIY methods to tackle mold, wall blisters, and peeling paint effectively.
1. How to Treat Mold on Walls
Mold growth on walls is not only unattractive but also harmful to your health. Here’s how you can tackle it:
Step 1: Start by brushing off the mold spots with a dry toothbrush. Once the loose mold is removed, take a soft cloth soaked in alcohol and gently wipe the area. This will dry out the mold and prevent it from spreading further.
Step 2: Mix bleach and water in a ratio of 1:99 and pour the solution into a spray bottle. Spray it evenly over the moldy wall. For more stubborn mold in humid conditions, increase the bleach ratio to 1:20.
Step 3: Allow the wall to dry completely. Once dry, use sandpaper to smooth the surface. Apply a waterproof primer before repainting the wall. This extra layer will help prevent future moisture-related mold issues.
Pro Tip: Ensure good ventilation in the room to speed up drying and reduce humidity.
2. How to Fix Wall Blisters
Wall blistering often occurs due to poor construction, excess moisture, or improper paint application. Follow these steps to repair blistered walls:
Step 1: Scrape off the blistered or peeling paint. If the issue stems from poor-quality wall filler, remove the old filler completely and replace it with a high-quality filler.
Step 2: For small blistered areas, focus only on the affected section. Smooth the edges, apply a primer, and repaint. For large blistered sections, scrape off the entire affected area, let it dry fully, and then apply fresh plaster before painting.
Step 3: During repairs, follow proper construction guidelines. Make sure the base layer of the wall is waterproof and address any visible cracks.
Step 4: Avoid painting during the rainy season, as moisture can compromise the paint’s adhesion. For the best results, always use the same brand of primer and paint.
Pro Tip: Test the wall for moisture levels before applying primer and paint. A moisture meter can help ensure you’re working on a fully dry surface.
3. How to Handle Peeling Walls
Peeling paint is another common issue that affects both the appearance and cleanliness of your walls. Here’s how to tackle it:
Step 1: Start by scraping off the peeling paint and removing any loose filler. Smooth out the edges with sandpaper and apply a layer of primer. Once the primer has dried, apply a fresh coat of paint.
Step 2: For severe peeling, remove the damaged wall layer entirely and apply a surface treatment or new primer before repainting.
Step 3: If the peeling paint is localized, dampen the affected area slightly with a spray bottle. Scrape off the peeling section. If no dust falls off during scraping, it’s a sign the original filler is still intact. Smooth the area with fine sandpaper and apply primer and paint as needed.
Pro Tip: Always choose high-quality paint and primer to ensure long-lasting results.
