A bad sheetrock repair can be hard to ignore once the light hits the wall. Seams show through the paint, patches sit higher than the surrounding surface, or a piece of tape starts to lift. If a previous repair left the wall looking worse, How to fix bad sheetrock jobs? starts with looking at the repair itself and deciding what needs to come out.
Find the problem before making another patch
It is tempting to reach for more joint compound and smooth everything over. That does not always work.
Look at the damaged spot from different angles. A raised seam may need sanding. Loose tape may need to be removed and replaced. A badly damaged section may call for a new piece of sheetrock instead.
Common signs of a poor repair include:
- A seam that remains visible after painting
- Tape that is wrinkled, loose, or showing through
- A patch that stands out from the rest of the wall
- Mismatched texture
The repair should be judged by what is underneath the paint, not just by how it looks from a distance.
Sometimes the old repair has to go
More compound is not always the answer. If a patch has already been built up too much, adding another layer can leave a noticeable hump.
For loose tape, removing the failed section and putting down new tape may be necessary. Uneven compound can be sanded back before another layer is applied. If the sheetrock itself is damaged, replacing that part may be the cleaner route.
There is no prize for saving a bad patch. The aim is a flat wall that does not call attention to the repair.
The new work has to blend in
A repaired wall can be perfectly solid and still look wrong.
Texture is one of the usual reasons. A smooth patch on a textured wall will stand out, especially after the paint dries. The same goes for an area that was not sanded properly before painting.
For that reason, How to fix bad sheetrock jobs? is also a question of matching the existing wall. Depending on what went wrong, the work may involve sanding, retaping, adding compound, or recreating the surrounding texture.
Know when starting over makes sense
Some bad sheetrock work can be cleaned up. Other jobs are easier to fix by removing the worst of the old work and starting again.
A small uneven area might only need sanding and another finish coat. Failed tape, badly damaged sheetrock, or a patch that has been built up too far may require more.
