Are you dealing with a cracked corner in your wall? It can be disheartening to look at whether it’s caused by general wear and tear or an accident. But the good news is that you don’t need to call in a professional; there are plenty of DIY methods available for how to fix crack in corner of wall.
Cracking a wall can be an unsightly and worrisome problem, but it doesn’t have to mean the end of your walls! Repairing a crack in the corner of a wall doesn’t have to involve tearing down drywall or calling in an expensive contractor. Instead, you can easily fix cracks using simple materials found at any hardware store and follow just a few easy steps.
This blog post will cover all the nitty-gritty details on fixing cracks in the corner of walls as quickly and affordably as possible.
What is Corner Cracking?
Corner cracking occurs when a wall experiences an excessive amount of shear force. This force can be caused by seismic activity or changes in temperature or humidity. It also happens on less dramatic causes like a door slamming, moving furniture, and other everyday activities that cause a structural shift in the wall.
When a corner cracks, it’s important to act quickly because the crack may get worse if left unchecked. In severe cases, the crack could spread across the entire wall and weaken its overall structure.
What Will You Need?
Before you start your repairs, make sure you have the following materials:
- Joint compound
- Piece of drywall tape (or fiberglass mesh)
- Putty knife
- Sandpaper, 120 and 220 grits
- Paintbrush or roller
- Primer paint (water based) if needed
Once you’ve gathered all your materials, you’re ready to begin!
10 Easy Steps on How to Fix Crack in Corner of Wall
Step 1. Clean Debris
Before you start any repairs, it’s important to make sure the wall is clear of dust and debris. Use an old brush or vacuum cleaner to remove everything that can interfere with your repair. If the crack is particularly dirty, use a damp cloth or sponge to clean it.
Step 2: Cut a Piece of Tape
After the wall is clean, cut a piece of drywall tape (or fiberglass mesh) just slightly longer than the length of the crack. Make sure to cut it straight so it fits nicely in the corner. You can use scissors or a utility knife to do this.
Step 3: Apply Tape
Now, place the tape into the crack and press firmly with your putty knife so that it adheres securely. If you’re using fiberglass mesh tape, cut off any excess material around the edges of the wall. Be careful not to stretch the tape too tightly.
Step 4: Spread Joint Compound
Once the tape is in place, use your putty knife to spread the joint compound over the crack and onto the surrounding area. Make sure to cover all areas completely, including both sides of the corner. Let the joint compound dry for 24 hours before continuing on with repairs.
Step 5: Sand Down Excess Joint Compound
After completely drying the joint compound, sand down any excess material with 120-grit sandpaper. Be careful not to sand too hard, as this can cause damage to the wall. For best results, use 220-grit sandpaper afterward for a smooth finish.
Step 6: Fill in Any Holes
Check for any holes or gaps that may have been left behind from sanding the joint compound. If there are any, use more joint compounds to fill them in and let dry for 24 hours. It will be easier to sand down if you apply too much material.
Step 7: Apply Primer Paint (Optional)
If you’re painting your wall after repairs, you’ll want to apply a primer coat first. This helps ensure that your paint adheres properly and creates an even finish. Remember to let the primer dry for a few hours before continuing on.
Step 8: Paint the Wall
Once the primer coat has dried, it’s time to start painting! Use either a brush or roller to apply your chosen paint color and ensure complete coverage. If you’re using a roller, make sure to cover the entire area in one direction before going back and painting in the opposite direction.
Step 9: Check for Gaps
After you’ve finished painting, check for any gaps or patches that may have been missed. If there are any, use more joint compound to fill them in and then sand them down after it has dried. Use the same technique you used in Step 6.
Step 10: Clean Up the Mess
Finally, clean up any leftover debris or dust created during repairs. Vacuum or sweep the floor and use a damp cloth to wipe down the walls if needed. And you’re done!
With just a few simple steps and materials, how to fix cracks in the corner of the wall can be easily completed without expensive contractors. All you need is a bit of patience and the right materials, and you’ll have your wall looking as good as new in no time. Good luck!
5 Additional Tips and Tricks
- Use a patching compound to fill the crack. Mix up a small batch of the compound according to package instructions, then use a putty knife or small trowel to press it into the crack.
- Apply a thin layer of spackle over the patching compound and allow it to dry thoroughly before sanding it down with fine-grit sandpaper.
- If the crack is large, use mesh tape to reinforce it. This will help keep the patched area from cracking again in the future.
- Use a high-quality primer before painting over the repaired corner to ensure an even finish and prevent any residual damage from showing through after the painting is complete.
- For larger cracks, you may need professional help for more permanent repairs, such as replacing wall panels or other components that contribute to the stability of your walls. Professional repair services are also better equipped to craft a seamless finish that blends perfectly with your existing walls.
- These tips and tricks should help you fix the crack in the corner of your wall quickly and easily. With some patience and DIY know-how, you’ll be able to get your wall back into shape in no time! If you struggle with the repair process, don’t hesitate to call a professional for assistance.
5 Things You Should Avoid
- Do not attempt to fill the crack with putty or sealant, as this can worsen it.
- Do not use a power washer for cleaning the wall: It may cause water seepage into the inner walls.
- Avoid using heavy materials such as plaster of Paris to fill the crack. This will make the wall weak and prone to further damage.
- Do not paint over the crack without properly repairing it first. The paint will eventually peel off and reveal an unsightly gap that needs work again.
- Never attempt to fix a corner wall crack on your own if you’re inexperienced. It is best to consult with a professional who knows how to fix cracks in walls correctly and safely.
- However, with the right tools and information, you’ll be able to get it done properly without any complications. Keep these tips and tricks in mind, as well as what not to do when repairing the corners of your walls!
