Peeling paint on concrete walls not only looks ugly but also causes the rigidness of the surface to take a toll, affecting their lifespan. So, only a long-lasting and effective solution is your best bet.
To fix peeling paint on concrete walls:
- Remove the peeling paint.
- Repair the wall.
- Do sanding.
- Apply primer to ensure that the paint adheres to the surface.
- Repaint the repaired part of the wall.
To simplify the entire process, we’ll explain the best method to fix peeling paint on concrete walls so that you can DIY with just a few supplies to seal the surface for an extended period.
Fixing Peeling Paint on Concrete Wall
If you don’t repair the concrete wall and repaint without addressing the issues, it will eventually affect the paint’s adhesion and cause it to begin flaking off.
Luckily, there is a straightforward way to get this done yourself with the steps mentioned below:
Step #1: Removing the Peeling Paint
Start peeling the paint and identify scuff marks, cracks, and holes in the concrete wall to repair them beforehand. Then, use a paint scraper to remove the peeling paint; otherwise, the wall can suffer more damage.
Put a tarp on the floor, so the wall scrapping doesn’t affect it.
Step #2: Repairing the Concrete Wall
If you’ve noticed any signs of deterioration on the concrete wall, apply a quick-setting patching compound with the help of a putty knife on the damaged part.
Apply the patching compound evenly to avoid any bumps in the wall.
Step #3: Sanding the Concrete Wall
Now, sand the concrete wall to smooth it, ensuring no grooves or lines. Use fine-grit sandpaper and rub it against the wall. However, don’t apply much pressure; only a little smoothness is enough.
Next, clean the wall thoroughly to remove any dust particles. You can use a damp sponge to clean more finely and let the wall dry afterward.
Step #4: Applying the Primer
Before applying paint, it’s mandatory to prime the concrete walls, adding durability and enhancing the surface. Then, simply put primer into a paint tray and use a brush to apply it on the wall surface to be painted.
Priming protects humid surfaces from mold and mildew.
Conclusion
Overall, the painted concrete surfaces are sturdy and last long, but the key is maintaining them nicely and addressing the underlying issues.
