When emulsion paint has bubbled on a wall, getting the bubbles "out" involves preparing the damaged surface before repainting.
To address areas where emulsion paint has bubbled, the process focuses on removing the compromised paint and creating a smooth, stable surface for a new coat. Based on common practices for fixing paint issues like bubbling, the initial steps involve careful surface preparation.
Here is a breakdown of the steps typically followed:
-
Step 1: Remove Loose Paint
- Wearing a dust mask for protection, gently scrape away any paint that is loose or flaking from the wall using a putty knife. This removes the bubbled sections and any poorly adhered paint around them.
-
Step 2: Repair Surface Imperfections
- Inspect the wall beneath the removed paint. If you find any holes or dents, apply filler to these areas. Ensure the filler is smoothed flush with the surrounding wall surface to create an even base.
-
Step 3: Smooth the Area
- Once the filler is dry and hard, sand down the entire area where you removed paint and applied filler. Use fine grit sandpaper for this step to ensure the surface is smooth and seamlessly blends with the surrounding wall, ready for repainting.
These steps effectively remove the physical manifestation of the bubbles (the lifted paint) and prepare the underlying wall for a fresh coat of emulsion, preventing immediate recurrence in the same spot due to poor adhesion or surface issues.
