Cracks in drywall are a common issue in many homes. Whether it’s due to settling foundations, moisture, or accidental impacts, knowing how to properly patch and repair a cracked drywall can save you both time and money. This guide will take you through the processes needed to restore your wall back to its original condition, ensuring that it is smooth and professionally finished.
Tools and Materials You’ll Need to Patch and Repair a Cracked Drywall
To get started with your drywall repairs, you will need a few essential tools and materials. These include drywall sheetrock, joint compound, a putty knife, sanding sponge or sandpaper, drywall tape, a utility knife, primer, and paint. In some cases, you might also require wall anchors, drywall, and screws, especially if the crack is due to structural issues or if you’re replacing a section of the wall.
Step-by-Step Guide to Repair Cracked Drywall
-
Assess the Damaged Drywall
Before you start any drywall repairs, it’s important to assess the extent of the damage. Examine the crack carefully to determine whether it’s a superficial hairline crack or a deeper, more structural issue. Hairline cracks are usually easier to fix, while larger cracks may require additional support like wall anchors, drywall, or even replacing a section with new drywall sheetrock.
-
Prepare the Area
Next, prepare the area around the crack. Clear any debris and use a utility knife to widen the crack slightly. This step helps the joint compound adhere better to the surface. If the crack is near a screw or nail, consider removing it and replacing it with wall anchor drywall for improved stability.
-
Apply Drywall Tape
For cracks larger than a hairline, apply drywall tape over the crack. This tape helps prevent the crack from reappears after the repair. Fiberglass mesh tape is a great option because it adheres well and is easy to work with.
-
Apply Joint Compound
Using a putty knife, apply a thin layer of joint compound over the taped crack. Make sure to feather the edges so that they blend smoothly into the surrounding wall. Allow the compound to dry completely, which usually takes about 24 hours.
-
Sand the Surface
Once the joint compound is dry, use a sanding sponge or fine-grit sandpaper to smooth the surface. Be gentle to avoid sanding too much and exposing the tape underneath.
-
Repeat if Necessary
For larger cracks, you may need to apply a second coat of joint compound. Repeat the process of applying, drying, and sanding until the surface is perfectly smooth.
-
Prime and Paint
After sanding, use a moist cloth and wipe down the wall to clear off dust particles. Then, put a primer in the area in which the fix was made with paint to properly bond with it. Once this is dry, paint over that area to color your wall.
Special Cases: Repairing Large Cracks on Drywall
For more extensive damage, such as large cracks or holes, you may need to cut out the damaged section and replace it with a new piece of drywall sheetrock. Secure the new piece in place using wall anchors, drywall, and screws before following the standard taping, compounding, and sanding process.
Tips for a Professional Finish For Damaged Drywall
Feaster the edges consistently to allow it to blend properly with the wall for a professional finish on damaged drywall. Be light with sanding to not create dips into the surface of the wall. Also, make sure to ventilate the area well while sanding and painting for a proper, clean finish.
