Bubbling Paint


I have started painting my new house this past week and have found that in a few places – mainly where there were scratches or nicks in the wall that I patched with polyfill – that the paint is bubbling and comes off very easily in large chunks. Why is this happening? I tried priming it in one room before paining, but even the primer is peeling off the walls.

  1. Always use Spackle to repair defects and learn the proper way to apply it… and then spot prime the repairs with pigmented shellac sealer primer before finish coating, using Sherwin Williams Classic-99 Latex

  2. The bubbling and peeling of paint in areas where there were scratches or nicks that were patched with polyfill is likely occurring due to poor adhesion of the paint to the surface. This issue commonly arises when the patched areas were not properly prepared or primed before painting. The polyfill, if not fully dried or sanded smooth, can create an uneven surface that prevents the paint from adhering properly. In addition, if the patched areas were not primed before painting, the paint may not have a proper foundation to bond to, leading to bubbling and peeling.

    To prevent this issue in the future, it is important to properly prepare the patched areas by allowing the polyfill to fully dry, sanding it smooth, and priming the patched areas before painting. Primer helps to create a smooth and uniform surface for the paint to adhere to, increasing its durability and preventing bubbling and peeling. Additionally, using high-quality paint and following proper painting techniques, such as applying thin, even coats and allowing sufficient drying time between coats, can also help to ensure a long-lasting and professional finish.

    In cases where the primer is also peeling off the walls, it may indicate a deeper adhesion issue with the original surface. In such instances, it may be necessary to remove the existing paint, properly prepare the surface, and then repaint the area following the recommended steps for patching, priming, and painting. By addressing the root cause of the adhesion issues and following proper painting procedures, you can achieve a durable and flawless finish for your newly painted house.
