When the ground gets wet and dries, it tends to move. As the house settles, cracks may develop in the drywall. Though this is normal over time, the crack is an eyesore and should be repaired. This project is not difficult to do and requires only a few tools. Take a weekend to repair all the cracks in your home. The unblemished walls will make the home look new.
You will need:
Step 2: Mix the setting type joint compound according to the manufacturer instructions. This type is preferred because it dries hard and has less cracking and shrinking. Spread it over the crack with the drywall knife. Fill in the crack and the area immediately surrounding it, flattening the compound against the wall as much as possible.
Step 3: Apply the paper tape to the crack. This reinforces the area, helping to prevent it from re-cracking. Press the tape against the crack with the drywall knife. Let the area dry.
Step 4: Apply a coat of fast-drying setting compound to the patch with the drywall knife, feathering it by covering a wider area and pressing on the edge of the spreading tool. Be sure to cover both sides of the tape. Allow this to dry for 40 minutes.
Step 5: Apply a finishing coat of pre-mixed vinyl compound with the drywall knife and immediately remove it from the area, a process called skimming. This will not bleed through the paint, so it is best to use as the final coat. Do not allow too much buildup or the repaired area will show when the wall is painted.
Step 6: Repaint the entire wall.
