Step-by-Step Guide to Repairing Walls After Wallpaper

Peeling off wallpaper shouldn’t be the hard part, right? You expect to see a smooth wall ready for a new coat of paint, but instead, you’re faced with torn drywall, stubborn glue, and random scratches. It’s disappointing, especially if you were looking forward to a clean, fresh start.

Here’s the upside: these problems are fixable. With the right painting services and a little guidance, if you want to do this on your own, learning how to repair wall after removing wallpaper is easier than you think. Whether you’re planning to repaint, apply new wallpaper, or simply enjoy a clean, bare wall, this step-by-step guide will show you exactly how to restore your walls so they look great again.

What Happens to Walls After Wallpaper Removal?

Even when you’re careful, removing wallpaper—especially older types pasted with heavy glue—can be rough on your walls. Some damage is hard to avoid. You might think you’ve done everything right, but once the wallpaper comes off, you’re left with a few surprises.

Common Issues You Might Notice

• Gouges and scratches: Removing stubborn wallpaper often leaves behind dents and scratches, especially if a metal scraper was used.
• Leftover adhesive: That sticky film you feel on the wall? It’s glue, and it’ll mess with your paint if you don’t get rid of it.
• Torn drywall paper: If you see fuzzy or brown patches, that’s the paper layer of the drywall being pulled off.
• Uneven textures: The surface may look fine at first, but once you paint over it, every little bump or raised spot will stand out.

Materials You’ll Need to Repair Walls

Before jumping in, gather what you need. This will make everything go faster and smoother.

• Drop cloths
• Painter’s tape
• Mild adhesive remover (or warm water and vinegar)
• Putty knife
• Joint compound or lightweight spackle
• Sandpaper (medium and fine-grit)
• A good-quality primer (preferably stain-blocking)
• Paint and supplies (roller, tray, brush)

Trust us—having everything ready from the start will save you a bunch of headaches later.

Step-by-Step: How to Repair Wall After Removing Wallpaper

Here’s how to bring your walls back to life after wallpaper removal.

Step 1 – Remove Any Remaining Adhesive

Even though the paper’s gone, the glue is probably still there. And if you try to paint over it, your new coat won’t stick right.

To get rid of it:

• Mix warm water with a bit of dish soap or vinegar.
• Or use a store-bought adhesive remover.
• Soak a sponge or rag in your solution and scrub gently, one section at a time.
• Rinse the wall with clean water and let it dry.

If your wall still feels sticky in places after cleaning, try gently going over the area with a sanding sponge. Be gentle—you’re not trying to strip the wall, just smooth it out.

Step 2 – Inspect for Wall Damage

Once everything is dry, take your time and look closely at the wall.

• Do you see fuzzy or brown patches? That’s torn drywall paper.
• Are there dents, dings, or small holes from scrapers?
• Feel for rough or bumpy areas that didn’t smooth out.

Knowing where the problem areas are now makes everything easier moving forward.

Step 3 – Patch Dents and Holes

For small holes and scratches, grab your spackle or joint compound and a putty knife.

• Apply a thin layer over the damaged spot.
• Feather the edges so the repair blends in with the rest of the wall.
• If it’s a deep dent or hole, you might need to apply a second coat after the first one dries.

Once dry, sand it down with fine-grit sandpaper until smooth, then wipe the area clean with a damp cloth.

Step 4 – Sand the Walls Smooth

You’ll probably have a few uneven areas after patching. Now’s the time to smooth everything out.

• Use medium to fine-grit sandpaper for this step.
• A sanding block or pole sander makes it easier, especially for big walls.
• Be careful not to sand too hard—you’re aiming for smooth, not bare drywall.

A quick, even sanding pass helps you create a consistent surface for priming and painting.

Step 5 – Prime the Walls Thoroughly

Many people are tempted to skip priming, especially when the wall looks “good enough.” But trust us—this step really matters. A good primer does more than just prepare the wall. It locks in all the patchwork you’ve done, hides any stubborn glue stains, and gives your paint something solid to stick to so it doesn’t peel or go on unevenly.

Look for a primer that’s made to block stains and safe for surfaces that had wallpaper before. Roll it on in thin, even layers, and don’t forget to get the corners and edges with a brush. Give it time to dry all the way before you move on to painting. You’ll appreciate it later when the first coat applies smoothly and stays in place.

Step 6 – Apply Paint for a Fresh New Look

Finally, the fun part—painting!

• Use a good-quality roller for smoother application.
• Choose the right finish for your space—eggshell and satin are great for most rooms.
• Paint in even, overlapping strokes, and let the first coat dry completely before applying a second.

Once you’re done, take a step back and admire your now-smooth, refreshed walls.

Pro Tips for Smoother Wall Prep Before Painting

Want to learn how to wall prep before painting? Here are a few bonus tips to make the job easier and your results even better.

Don’t Rush the Drying Process

We get it—you want to finish. But giving each step time to dry (especially primer and joint compound) is essential for a smooth finish. If you rush it, you’ll risk bubbles, cracks, or peeling paint later on.

Always Use a Primer After Wallpaper Removal

It might be tempting to jump straight into painting, especially if the wall looks okay after sanding, but skipping primer is a mistake. Here’s why priming is worth it:

• It seals up repaired areas so paint doesn’t soak in unevenly
• It blocks old adhesive stains from bleeding through
• It helps your paint stick better and last longer

Think of primer as the foundation that holds everything together—it’s one step you don’t want to skip.

When to Consider Skim Coating for Severely Damaged Walls

Sometimes, even after patching and sanding, the wall still feels bumpy or looks blotchy. If that’s the case, skim coating might be the best fix.

• Skim coating means spreading a thin layer of joint compound over the entire wall
• It smooths out rough or uneven areas and gives you a clean, fresh surface
• It takes more time, but it’s the best way to deal with walls that have heavy damage

Skim coating is worth the effort if you want a flawless finish, especially before painting.

When to Call in a Professional Painter

There’s no shame in asking for help, especially when your walls are in rough shape or you’re short on time. Here are a few situations where calling a pro might be your best bet at smoothing damaged drywall.

Considerable Surface Damage or Poor Adhesion

If your walls are peeling, flaking, or have widespread drywall paper damage, a professional painter can handle it without making things worse.

Multiple Layers of Old Wallpaper Residue

Some older homes have wallpaper layered on wallpaper, each with its own adhesive. Removing and repairing that properly takes time, patience, and the right tools.

Time-Sensitive Repainting Projects

If you are considering repainting after wallpaper, preparing for a move, an open house, or a renovation deadline, a painting crew can get the job done quickly and cleanly.
