How to Fix Drywall Cracks in Corners

Say Goodbye to Drywall Cracks in Corners with These Easy Fixes

Drywall cracks in corners can be a common issue in many homes. They can be unsightly and can also lead to further damage if not addressed promptly. Fortunately, fixing drywall cracks in corners is a relatively simple process that can be done by following a few easy steps.

Step 1: Identify the Crack

The first step in fixing drywall cracks in corners is to identify the crack. This can be done by visually inspecting the corners of the room and looking for any visible cracks. Sometimes, cracks may be difficult to spot, so it's important to run your hand over the corners to feel for any irregularities.

Step 2: Clean the Area

Once you have identified the crack, the next step is to clean the area around it. Use a damp cloth to wipe down the area and remove any dust or debris that may have accumulated. This will ensure that the repair material adheres properly to the surface of the drywall.

Step 3: Apply Joint Compound

The next step is to apply joint compound to the crack. Use a putty knife to spread a thin layer of joint compound over the crack. Be sure to press the compound firmly into the crack to ensure that it fills the entire space.

Step 4: Apply Drywall Tape

After the joint compound has been applied, the next step is to apply drywall tape over the crack. Cut a piece of drywall tape to the length of the crack and press it firmly into the joint compound. Use the putty knife to smooth out any wrinkles or bubbles in the tape.

Step 5: Apply Second Coat of Joint Compound

Once the drywall tape has been applied, the next step is to apply a second coat of joint compound. Use the putty knife to spread a thin layer of joint compound over the tape, making sure to cover it completely.

Step 6: Sand and Smooth

After the second coat of joint compound has dried, the next step is to sand and smooth the surface. Use a sanding block or sandpaper to gently sand the surface of the joint compound until it is smooth and even with the surrounding drywall.

Step 7: Paint

The final step in fixing drywall cracks in corners is to paint the repaired area. Use a paintbrush or roller to apply paint that matches the surrounding wall. Allow the paint to dry completely before touching or adding another coat.

In conclusion, fixing drywall cracks in corners is a simple process that can be done by following these easy steps. By identifying the crack, cleaning the area, applying joint compound and drywall tape, applying a second coat of joint compound, sanding and smoothing, and painting, you can have your drywall looking as good as new in no time.
