How to Repair Drywall Cracks in Corners
Drywall cracks in corners can be an unsightly and frustrating issue for homeowners. They can occur due to a variety of reasons such as settling of the foundation or house, seasonal changes, or too much moisture. If left untreated, these cracks can worsen and become a significant problem. However, repairing drywall cracks in corners can be an easy DIY project with the right tools and techniques.
Tools and Materials Required
Before starting the repair process, you will need these tools and materials:
- Pre-mixed joint compound
- Drywall tape
- Sandpaper (150-grit and 220-grit)
- Putty knife
- Flexible putty knife or drywall knife
- Vacuum cleaner/brush
Step-by-Step Guide
Follow these steps to repair drywall cracks in corners:
Step 1: Clean the affected area
Use a vacuum cleaner and brush to remove any debris in the crack and surrounding area. Make sure the surface is clean and dry before beginning the repair.
Step 2: Apply drywall tape
Cut the drywall tape to the length of the crack and apply it firmly over the crack. Make sure the tape lies flat and adheres to the wall.
Step 3: Apply joint compound
Use a putty knife to apply joint compound to cover the drywall tape. Make sure the compound spreads smoothly and evenly over the tape and the wall. Allow the compound to dry completely, following the manufacturer’s instructions.
Step 4: Apply second coat of joint compound
Once the first layer of joint compound is dry, apply a second layer over it, using a flexible putty knife or drywall knife. Spread the compound evenly and smoothly, ensuring that it is slightly wider than the first layer. Allow the compound to dry again.
Step 5: Sand and feather the edges
Use a 150-grit sandpaper to sand the dried compound until the surface is smooth and even. Use a 220-grit sandpaper to feather the edges of the compound into the surrounding wall, ensuring a seamless finish.
Step 6: Apply final coat of joint compound
Apply a final thin layer of joint compound over the repaired area to further blend it into the wall. Allow the compound to dry completely.
Step 7: Sand and clean the area
Sand the repaired area once again with 220-grit sandpaper to create a smooth finish. Clean the area with a vacuum cleaner or brush to remove any dust, and wipe the surface clean with a moist cloth before painting.
Conclusion
Repairing drywall cracks in corners is an easy DIY project that can significantly enhance the appearance of your walls. By following these simple steps and using the right tools and materials, you can repair drywall cracks in corners and achieve a seamless and professional-looking finish.
If you notice a crack in the drywall in the corner of a doorway or wall, you might be wondering how to fix it. Fortunately, repairing drywall cracks in corners is quite simple and can be done in only a few steps.
Begin by thoroughly assessing the crack and the area around it. Brittle, crumbling drywall may be more extensive than initially expected, so removal of the affected area might necessary. Afterwards, use a utility knife to lightly score an outline of the damaged area. Take a drywall saw to cut along the outline and carefully remove the drywall.
Next, measure the height, width, and depth of the now exposed opening. Utilize these dimensions to determine the size of the drywall piece needed to replace the removed section. Trace around the piece onto the disused drywall using the measurements and cut it with a utility knife or drywall saw.
Drywall mud, a paste-like material, will be needed to fill the gap. Use a drywall taping knife or putty knife to apply the mud to the corner. Be aware that if the affected corner is in a visible spot, the drywall mud should match the existing pattern. Apply the mud, level it with the knife, and allow it to dry.
It might be necessary to apply several layers of mud until a smooth, uniform result is achieved. Once the drying process is complete, sand the area with 120-150 grit sandpaper. Sanding should make the transition from the existing wall to the new corner more refined.
Finally, paint the corner as necessary. Drywall repair for corners is now complete, with the crack successfully patched and blended in. While tricky to do, this procedure can be done with the right tools and materials and the correct amount of time and effort.
