Removing wallpaper can give your walls a fresh start, but it often leaves behind damage that requires repairing the drywall. This process can seem daunting, especially when unexpected problems arise. Understanding these common issues and how to address them will make the job easier and ensure your walls look smooth and flawless. Here are some of the most common problems you might encounter when repair drywall after removing wallpaper:

1. Adhesive Residue on Walls

One of the most frequent issues is leftover adhesive or glue on the drywall. This residue can prevent paint or new wallpaper from adhering properly.

Solution: Use a wallpaper adhesive remover or a mixture of warm water and dish soap. Gently scrub the walls with a sponge or cloth until the residue is gone. Avoid using harsh tools that could damage the drywall.

2. Torn Drywall Paper

Removing wallpaper can sometimes tear the top layer of the drywall paper, leaving unsightly rough patches.

Solution: Sand down the torn areas gently to smooth them out. Apply a thin layer of primer-sealer over the damaged spots to prevent bubbling when you apply joint compound later.

3. Dents and Gouges

Using scrapers to remove stubborn wallpaper can result in dents or gouges in the drywall.

Solution: Fill these imperfections with joint compound. Use a putty knife to apply the compound evenly and let it dry completely. Sand the area smooth before priming and painting.

4. Stains on the Drywall

Wallpaper glue or paint may leave stains on the drywall surface, which can bleed through new paint.

Solution: Apply a stain-blocking primer to cover the stains and create a clean surface for painting. This step ensures a flawless finish and prevents discoloration.

5. Bubbling or Peeling Drywall

Sometimes, applying water or adhesive remover can cause the drywall paper to bubble or peel.

Solution: Cut away the bubbled areas with a utility knife. Apply a layer of primer-sealer to the exposed drywall, then fill in the area with joint compound. Sand it smooth once dry.

6. Uneven Surface

After wallpaper removal, the wall surface may feel uneven due to leftover glue or patchy repairs.

Solution: Sand the entire wall lightly to ensure a smooth, even surface. Use a sanding block or an electric sander for larger areas. Clean the dust thoroughly before applying primer.

7. Cracks in the Drywall

Small cracks may appear in the drywall, either from the wallpaper removal process or previous damage.

Solution: Use a joint compound to fill the cracks. For larger cracks, apply a piece of drywall tape over the crack before covering it with compound. Sand and smooth the surface once it’s dry.

Wrapping up

Repairing drywall after wallpaper removal can be tricky, but knowing how to handle common problems makes the process much smoother. With the right tools and techniques, you can restore your walls to their original condition and prepare them for painting or new wallpaper. Take your time, follow these steps, and enjoy your refreshed space!
