Project Snapshot

Repairing drywall cracks renews the look of your interiors and ensures structural longevity. This project involves cleaning out cracks, applying joint compound, sanding, and repainting the area to blend the repair seamlessly with the rest of your wall. Most cracks can be handled in a day with basic materials. This repair is ideal for homeowners looking to improve home aesthetics without major renovations. Proper crack repair also prevents minor issues from becoming bigger headaches down the road.

Tools and Materials

For a smooth drywall crack repair, you will need a putty knife, utility knife, sandpaper or sanding block (120-220 grit), a joint compound (pre-mixed is easiest), drywall tape (if the crack is large), a sponge, primer, and matching paint. Lay down a drop cloth to catch dust and debris. Make sure to have a dust mask and safety glasses if you’re sensitive to airborne particles. Having all your tools ready ahead of time will save you time and make the process smoother.

Step-by-Step Instructions

Begin by gently widening the crack with a utility knife to remove any loose material and create a V-shaped groove. Use a damp sponge to wipe away dust and debris so the compound adheres well. Apply joint compound with a putty knife, pressing it firmly into the crack and smoothing it flush with the wall surface. If the crack is wider than an eighth of an inch, embed drywall tape into the compound to prevent it from returning. Let the compound dry completely, sand it smooth, and then repeat the compound layer and sanding as needed until the repair is imperceptible. Once satisfied, cleanse the area of dust and prime before painting.

Recently, one of our Handydads team members helped a family prepare for a big holiday gathering. They noticed their living room wall was showing hairline cracks just a day before hosting. Using these techniques, our pro was able to patch the cracks efficiently and leave the wall looking freshly painted. The family was thrilled with the flawless result and relieved that their guests would only see a beautifully maintained home.

Top 5 Mistakes

Skipping proper crack preparation by not removing loose drywall. Rushing the drying time for joint compound which leads to uneven surfaces. Over-sanding and damaging the existing drywall. Neglecting to prime the repaired area before painting. Failing to use drywall tape on larger cracks, causing them to reappear.

Tool and Material Recommendations

Look for a flexible and easy-to-spread joint compound for amateur repair jobs. A high-quality putty knife with a comfortable grip helps ensure smooth application. Use fiberglass mesh drywall tape for larger or problematic cracks. For paint, match it to your existing wall with a test sample before applying. Choose an ergonomic sanding block for consistent results and less strain on your hands.

Quick Tips and Hacks

Apply multiple thin layers of joint compound rather than one thick coat to avoid ridges. Feather out the edges with each layer for invisible blending. Always sand between coats for smoothness. Clean the repair area thoroughly before priming. Practice your putty knife technique on scrap drywall before starting on your actual wall.
