Bubbles in Paint


We bought a good paint with the primer in it. After applying it bubbles appear in small places on the wall. How do I fix this problem so we can finish the other walls?

  1. A "Good Paint with the primer in it" … that was your mistake… the whole concept of having a primer and finish paint all in one is only a BIG Sales Gimmick… in recent years… and primers should always be applied separately first before the finish coat (assuming that any priming is in fact actually required in the first place… usually not for pre painted surfaces)… now you need to block-sand all those surfaces, prime them with a Pigmented Shellac Sealer Primer then finish coat with a "Good High Quality Paint" like Sherwin Williams Classic-99, Flat…

  2. To address bubbling paint issues on your wall after using a primer-included paint, here are the steps you can follow to fix the problem and proceed with finishing the other walls:

    1. **Identifying the Cause**: Bubbling can be caused by various factors such as moisture, improper surface preparation, or application technique. It is crucial to identify the root cause to prevent recurrence.

    2. **Allow Proper Drying Time**: If the bubbling is minimal and the paint is still wet, allow it to dry completely before taking any action. Avoid touching or attempting to fix it until it is fully dried.

    3. **Sand the Bubbles**: Once the paint is dry, gently sand down the bubbled areas using fine-grit sandpaper to smooth out the surface. Be careful not to sand through to the underlying surface or primer.

    4. **Repair the Surface**: After sanding, inspect the surface for any imperfections such as uneven patches or exposed primer. Use a suitable filler or spackling compound to repair any damaged areas before repainting.

    5. **Apply a Second Coat**: To ensure a uniform finish, apply a second coat of paint over the repaired areas, feathering the edges to blend with the surrounding surface. Use the same paint used initially for consistency.

    6. **Check for Proper Ventilation and Humidity**: Ensure that the room has adequate ventilation and the humidity levels are within the recommended range for painting to prevent further bubbling issues.

    7. **Assess Future Painting Conditions**: If the bubbling persists or occurs on other walls, consider addressing any underlying issues such as moisture intrusion, poor surface preparation, or incompatible products before proceeding with painting.
