How to Repair Drywall Hole In a Wall

A damaged wall that is drywall does not need guesswork. The repair depends on the size of the damage, the condition of the drywall around it, and how smooth you want the wall to look after painting.

At MrWalls Drywall & Painting, we repair drywall walls with proper repairs that hold, blend in, and leave the wall ready for primer and paint.

What Is Drywall Wall Repair

Drywall is a building material that many people use when they build ceilings and walls. A drywall repair can be as small as filling a nail hole or as involved as cutting out a damaged board and installing a new one.

The main goal is simple. Get back to solid material. Build the repair flat. Finish it so it does not stand out after painting.

How to Repair a Small Drywall Wall Hole

Small holes from nails, screws, or anchors usually need filler or joint compound, light sanding, and spot primer. The key is not leaving a raised spot. If the filler sits proud of the wall, the patch shows once the paint dries.

Small dents and shallow chips also fall into this kind of repair. These are usually simple as long as the drywall paper is still sound.

How to Repair a Medium Drywall Wall Hole

A medium hole often needs more than filler. If the opening is too big, the repair needs support behind it. That includes adding backing, cutting a piece of drywall to fit, taping the seams, and coating the area in multiple layers.

Each coat needs to dry before sanding and recoating. Rushing this step leads to delayed shrinkage and cracking that will show up after the area is painted. The surface of the compound may be dry, but if the mud behind it is still wet, it will eventually dry out, causing ugly sunken areas.

How to Repair a Large Drywall Wall Hole

A larger hole needs a stronger repair. First, the damaged sheet needs to be cut out and replaced. Backing wood along the edges may need to be added so the new piece has support. After the sheet is installed, the seams get taped and coated with compound.

This is where many DIY repairs go wrong. The patch may feel solid, but if the finished work is rough, the wall still looks bad after painting. Taking the time to do multiple thin coats and properly sanding the compound smooth is the only way to get a wall that looks good.

What to Do if the Drywall Paper Is Torn

Torn drywall paper is common after wallpaper removal, bad patch removal, or an old repair that broke loose. You do not want to mud over loose paper and hope for the best. The weak paper needs to be cut back, and the surrounding paper sealed first.

Once the surface is stable, the wall can be skimmed or patched as needed.

How to Repair Cracks in a Drywall Wall

Wall cracks are different from holes, but they still need the right repair technique. A hairline crack may need to be opened with a utility knife, retaping, and then coating the area smooth. If the joint tape has failed along the crack. A simple wipe of compound over the top will often crack again. Be sure to cut out any tape surrounding the crack before taping and coating.

If the crack keeps coming back, you may have a structural issue in the framing that needs to be addressed, and a professional should be brought in.

How to Repair a Drywall Wall with Water Damage

If drywall gets wet from a leak, the first step is fixing the leak. After that, the drywall has to be checked for swelling, softness, staining, and loose tape. Some water-damaged walls need a small section cut out and replaced. Others need a full sheet replaced.

Paint does not fix soft drywall. If the board has lost strength, it needs to come out and be replaced. You can tell by pushing on the area with a finger. If you notice the board has sagged or looks deformed, replace that section.

Smooth Wall and Textured Wall Repairs

A patch on a smooth wall has to be finished more carefully than most people expect. Side light from windows shows every ridge and sanding mark. On textured walls, the repair still needs to be flat before the texture goes on, but minor stuff usually gets hidden with the texture.

This is why a repair that looks fine before paint often stands out after the room is finished. The sheen from the paint will make any defects more visible than with primer alone.

When a Wall Needs Skim Coating

Some walls have too many patches, rough seams, torn paper spots, or old paint roller texture buildup for spot repair alone. In that case, skim coating the wall may be the way to go after you repair the bad areas. A skim coat helps smooth the surface and blend repair areas before primer and paint. It creates a surface with a uniform texture and porosity. Skim coating is also known as a level 5 finish.

We often recommend skim coating after wallpaper removal or if there are multiple repairs on the same wall. Especially if the finish paint is satin or semigloss, and large windows let bright sunlight shine across the wall at certain times of the day.

Common Repair Mistakes

We redo a lot of wall patches that failed for simple reasons. Filler used in a hole that was too large. No backing behind the repair. Tape lines left unsanded. Sanding marks that are not feathered out. Painting over an unprimed repair.

Most bad repairs do not fail because the wall was too damaged. They fail because the steps were rushed or not done thoroughly. The solution is usually skim coating, feathering out the repair wider, and taking your time sanding. I usually sand with 150-grit first to get the high spots and then finish with 220 or 240-grit sandpaper.
