Tips

  • Always cut the replacement patch slightly larger than the damaged area for a perfect fit.
  • Use backing supports to ensure a strong and stable repair.
  • Fill joints before applying mesh tape for a stronger bond.
  • Feather out the joint compound to create a smooth, seamless transition.
  • Paint the entire wall to avoid noticeable touch-ups.

Common Mistakes to Avoid

1. Using the wrong size filler

Reason: Choosing a filler that's too small will leave gaps, while using one that's too large can create a bulge or make sanding difficult.
Solution: Select a filler that's slightly larger than the hole to ensure complete coverage and easy sanding.

2. Insufficient drying time

Reason: Rushing the drying process can lead to cracking or crumbling of the filler, resulting in an uneven surface.
Solution: Allow the filler to dry completely according to the manufacturer's instructions before sanding.

3. Skipping the primer

Reason: Applying paint directly to the filler can result in uneven absorption and a less professional finish.
Solution: Always prime the repaired area before applying paint to ensure a smooth, consistent color.

FAQs

What's the best filler to use for patching doorknob holes?
For most holes, a high-quality spackling paste or lightweight patching compound works best. These are easy to apply and sand smooth. For larger holes, you might consider a joint compound.
How do I prevent the patch from cracking after it dries?
The key is proper preparation and application. Ensure the hole is clean and free of dust. Apply the filler in thin layers, allowing each layer to dry completely before adding the next. This prevents shrinkage and cracking. Also, feather the edges of the patch to blend seamlessly with the surrounding wall.
