How to Fix Bubbling Paint on Walls: Step-by-Step Guide for a Smooth Finish
If you’ve ever been frustrated by ugly paint blisters and bubbles appearing on your freshly painted walls, you know how much of a headache it can be. Bubbling paint not only looks unsightly, but it can also indicate underlying issues such as moisture problems or poor adhesion. The good news is that with the right approach, you can fix these bubbles and restore your walls to a smooth, even finish. Here’s a step-by-step guide to help you tackle this issue effectively.
Why Does Paint Bubble Up on a Wall?
The first step in fixing bubbling paint is identifying what’s causing the problem. Knowing the underlying cause helps you prevent future issues and ensures that the fix is long-lasting. Here are some common reasons why paint bubbles form:
- Moisture Trapped Under the Paint
One of the most common causes of bubbling paint is trapped moisture. This can happen when walls are painted while they are still damp, or when moisture seeps in from leaks in the wall or roof. If you suspect moisture might be an issue, you may need to check for water, smoke, and mold damage on your walls before moving forward. A professional water, smoke, and mold damage repair service can help identify any underlying issues that might need fixing before painting. Water, Smoke, and Mold Damage Repair - Dirty or Dusty Surfaces
Another common culprit is a dirty or dusty surface. Paint won’t adhere properly to a surface covered in dust, dirt, or grease, which can cause it to peel and bubble. Before painting, it’s essential to clean the walls thoroughly. If the surface is damaged, you may need drywall repair to smooth things out and create a good base for painting.

If the wall is too hot, cold, or damp when you paint, the moisture can cause the paint to bubble. It’s important to ensure your walls are completely dry and that the weather conditions are ideal for painting.
How to Identify the Source Behind Paint Bubbles
Before reaching for the scraper and paint, it’s important to identify what’s causing the bubbles. Here are a few tests to help pinpoint the issue:
- Moisture Test for Walls
To check for moisture, place a small piece of aluminum foil on the affected area and seal the edges with tape. Leave it for about 24 hours. If condensation forms on the back of the foil, it means there’s too much moisture in the wall. If that’s the case, the issue may be water-related. - Inspect for Leaks and Dampness
Look for leaks in the ceiling, pipes, and exterior walls. Even small amounts of water vapor can cause paint to bubble. - Check for Mold or Dampness
Peel back the bubbled paint and inspect the substrate beneath it. If you notice soft drywall or mold growth, it’s clear that moisture is the issue. In such cases, plaster repair may be required to fix the underlying structure before repainting. Plaster Repair Services
How To Fix Bubbling Paint on Walls: Step-by-Step Guide
Once you’ve identified and resolved the underlying issue, you can proceed with fixing the bubbled paint. Here’s a step-by-step guide to ensure a smooth and even finish:
Tools and Materials You’ll Need:
- Putty knife or paint scraper
- Medium and fine grit sandpaper
- Moisture-resistant or stain-blocking primer
- Matching paint
- Paintbrush or roller
- Cleaning cloths
Steps to Fix Paint Bubbling:
Step 1: Scrape Off the Bubbled Paint
Start by carefully scraping off any bubbled or flaking paint with a putty knife or paint scraper. Be sure not to damage the drywall or plaster underneath. If the area is large, you may need to sand it smooth to even out the surface.
Step 2: Sand the Area Smooth
Use medium-grit sandpaper to smooth out the area, then follow up with fine-grit sandpaper for a smooth finish. Clean the area with a damp cloth to remove any dust and allow it to dry before moving on to the next step.
Step 3: Apply Primer
Priming the repaired area is crucial for the new paint to adhere properly. Use a moisture-resistant or stain-blocking primer, and let it dry completely before applying your final coat of paint. This is especially important if there was moisture or mold present earlier.
Step 4: Repaint the Wall
Once the primer has dried, apply your matching paint. You should apply at least two coats, allowing the first coat to dry before applying the second. Make sure to blend the new paint with the surrounding area for a seamless finish.
How to Avoid Your Paint from Bubbling Again
Now that your walls are smooth again, it’s essential to take preventive measures to avoid future bubbling. Here are a few tips to keep your paint looking pristine:
- Keep Walls Dry
Trapped moisture or leaks are often the primary cause of bubbling paint. Make sure to fix any leaks in your home, and use a dehumidifier in damp areas such as basements or bathrooms. Ensure proper ventilation in moisture-prone areas. - Use the Right Paint and Technique
Always use the correct type of paint for the surface and ensure you’re following the manufacturer’s recommended temperature and humidity levels for application. If you’re painting over oil-based paint, make sure to sand and prime the surface properly first. - Proper Surface Preparation
Before painting, wash the walls to remove any dust, grease, or dirt. Sand glossy surfaces for better paint adhesion, and never skip the primer.
