How Do You Fix Peeling Paint Before Painting?
No matter what the degree of your chipping paint, or cracking paint that peels as you touch it, you do need to prepare it ready for painting.
Even if the surfaces are flat, once you apply paint to old paint, you may see it peel off. You have many different types of paint, and putting the wrong one on top of another is a recipe for disaster.
Here are the guidelines you need to repair and prepare your surfaces ready to apply your fresh coats of paint.
Items You Need
- Fine-grit sandpaper
- Plastic drop cloth or tarp
- Painters tape
- Wire brush or paint scraper
- Putty knife
- Patching compound
- Personal protective equipment
- Tack cloth or sponge
- Roller and brush
Prep the Workspace
Always wear protective clothing. Also, place a piece of plastic or a tarp close to the work area and tape it off around baseboards. Finally, put drop cloths where you could splash paint.
Remove Problem Paint
You can’t paint on peeling surfaces that have oils in them. You need to remove all this from the affected areas. Use your wire brush or paint scraper and remove the loose flakes. Make sure not to press too hard on the surface as you may do more damage.
Repair the Surface
You may see cracks or holes after removing the paint. Use your putty knife and patching compound to fill any gaps. Smooth off any excess and let it dry properly.
Create a Smooth Surface
No matter if you had to patch up any areas or not, you’ll want to sand the area to make sure a surface is devoid of any grooves or lines. Using a fine-grit sandpaper and sanding block, smooth down the area. Check it is smooth with your hand.
The area needs to be very clean before you begin painting. New paint needs to adhere, and if the area isn’t clean, you’ll end up with the same peeling issues.
Using a tack cloth or slightly damp sponge, and wipe all the areas you will paint. Next, do the same again with a lint-free cloth and let the area dry thoroughly.
Priming Your Area
Moisture can be the main reason for peeling paint; thus, you need to be sure your newly painted area won’t have any moisture under your paint. Primer helps seal the surface against moisture and thus helping your paint to stick as it should.
Once you have carried out all your prep, you can begin painting one of two coats of your new paint. (Read Mesh vs Paper Drywall Tape)
