2. Clean the Walls

Once you’ve determined the cause of the damage, you can start to clean the walls. If mold or mildew is present, you’ll need to use a special cleaner. You can find these at most hardware stores. First, you’ll need to remove any loose paint or wallpaper. If the walls are very dirty, you may need to wash them with mild detergent.

Be sure to rinse the detergent completely. If the walls are just dirty, you can use a sponge and some warm water to clean them. Avoid using too much water, as this can damage the walls.

3. Remove Damaged Wallpaper

You’ll need to remove the damaged portion if your walls are covered in wallpaper. You can do this by scoring the wallpaper with a utility knife and then peeling it off. First, score the wallpaper in a square around the damaged area. Be careful not to damage the drywall underneath. Next, peel off the wallpaper starting at one of the corners.

If the wallpaper is resistant, you can use a putty knife to help peel it off. Once the damaged portion is removed, you can patch the drywall and paint it. If the wallpaper is hard to remove, you can use a steamer to loosen it. Be careful not to damage the wall underneath.

4. Fill in Cracks and Holes

If there are any cracks or holes in your walls, you’ll need to fill them in before you can paint or wallpaper over them. You can use spackle or drywall compound to fill the holes. First, apply the spackle or drywall compound to the hole with a putty knife.

Be sure to fill it in completely. Next, use sandpaper to smooth out the surface. Avoid using too much pressure, as this can damage the wall. Once the area is smooth, you can paint or wallpaper over it.

5. Apply a Primer

When painting your walls, you’ll need to apply a primer before you paint. This will help the paint to stick to the walls and will also help to cover up any damage. Be sure to apply the primer evenly to all damaged areas.

First, apply the primer to the walls with a roller. Be sure to use an extension pole to reach the high areas. Next, use a brush to paint the primer into the cracks and crevices. Once the primer is dry, you can paint it with your chosen color.

6. Paint the Walls

Once the primer is dry, you can paint the walls with your chosen color. Be sure to use a roller for large areas and a brush for smaller areas or touch-ups. Also, don’t forget to paint the trim! First, paint the top of the trim closest to the ceiling using an angled brush.

Next, use a tapered brush to paint the sides of the trim. Finally, use a small brush to paint the details and edges. Try to do two coats of paint for even coverage. Let the paint dry completely before moving on to the next step.

7. Hang Wall Decor

Another way to cover up damage on your walls is to hang wall decor. This can include paintings, photographs, or even tapestries. First, choose the location for your wall decor. Next, use nails or screws to secure it to the wall. Be sure to use the appropriate hardware for your type of wall decor. Finally, enjoy your new decoration! You can always move it around or change it out later if you need to.

8. Install Insulation

One way to prevent damage to your walls is to install insulation. This will help to keep your walls dry and free from mold or mildew. You can find insulation at most hardware stores. First, measure the area you need to insulate.

Next, cut the insulation to size and fit it into the space. Be sure to seal any gaps or cracks with caulk. Finally, apply a layer of drywall over the insulation. This will help to protect it from damage.

If the damage to your walls is extensive, you may need to replace the drywall. This is a more involved repair and should only be done by a professional. First, remove the damaged drywall using a utility knife. Be careful not to damage the wall behind it. Next, measure the area and cut a piece of new drywall to fit.

Apply joint compound to the edges of the new drywall and secure it in place. Be sure to use screws or nails for extra support. Finally, apply joint compound to the seams and let it dry. Once it’s dry, you can sand it down and paint it to match the rest of your wall.
