Top 5 Reasons For Peeling Paint On Drywall


Peeling paint is a common issue faced by homeowners and renters alike. Not only does it affect the aesthetics of your walls, but it can also be a sign of underlying problems. When it comes to drywall, understanding the reasons behind the paint peeling off the wall like skin helps prevent future damage and maintain your walls’ look and integrity. Here, we’ll talk about the top five reasons that cause paint to peel on drywall and how to address these issues effectively.

First, peeling paint is not just ugly, messy, and necessary to fix; it can be a sign of something more going on behind your walls or ceiling. If you have to peel paint, your painting contractor will fix it so it doesn’t happen again. There are many reasons why the paint could be peeling in your bathroom, and here are some of the most common causes to consider. Knowing the root of the problem is an important first
step to fixing the issue.

Reasons For Peeling Paint on Drywall

Reason #1 For Peeling Paint on Drywall: Water Leak

Your peeling paint may be trying to tell you something—that there may be a leak in your roof or water pipes that needs to be fixed. Determine whether this is the case by inspecting all possible areas of your home that could be causing moisture in the bathroom. Look on the roof for missing shingles, and indoors, look at baseboards and flooring for water stains.


Reason #2 Improper Surface Preparation

If the walls that have peeling paint are dirty and damp, have old paint or other residues on them, and the surface wasn’t properly dried and primed before painting, the result will be peeling paint.


Reason #3 Wrong Paint Type

Bathrooms are a tough customer for paint. Whenever your bathroom sees a lot of shower traffic the paint will peel. In addition, using oil paint over the top of latex paint, or if oil and latex paint are mixed in error, it can also peel.


Reason #4 The Paint Didn’t Dry Between Coats

Painting requires patience and can be tedious. If the first coat of paint didn’t completely dry before the second coat of paint was applied, then the peeling paint might have been caused by the trapped moisture underneath.


Reason #5 High Humidity

Who doesn’t like a long, hot shower most days? A bathroom will get steamy, and if there isn’t proper ventilation from windows or a fan, the walls and ceiling are going to feel the effects of this excessive moisture, and the paint will peel. Ensure your bathroom has good ventilation and a fan that’s powerful enough for the space to protect and ward off moisture. If the exhaust fan is the right size for the room, clean it to improve its effectiveness.

Step 1: Assess the Damage

For small holes or cracks, a simple patch job with a joint compound will suffice. However, for larger holes, you might have to cut out the damaged area and replace it with new drywall.

2: Cut Out the Damaged Drywall

Use a utility knife to cut out a square or rectangular section around the damaged area. Be careful not to cut through any wires or pipes behind the drywall.

Step 3: Prepare a Drywall Patch

Cut out a new piece of drywall to the exact size of the removed section using a drywall saw.

Step 4: Install Backup Support

If the hole is large, you will need to install a piece of plywood or scrap wood as backing support inside the wall. Attach this backing using screws.

Step 5: Install the Drywall Patch

Place the new drywall piece into the hole and secure it in place using drywall screws, ensuring it’s flush with the existing wall.

Step 6: Apply Drywall Tape and Joint Compound

Apply drywall tape around the edges of the patch. Then, using a taping knife, spread a layer of joint compound over the tape and the drywall screws. Allow it to dry completely.

Step 7: Sand and Paint

Once the joint compound is dry, sand the surface until it’s smooth and blends with the rest of the wall. Clean off the dust and apply a coat of primer. After the primer has dried, paint the patched area to match the rest of your wall.
