How to Fix a Drywall Crack

Drywall cracks are a big problem in homes and can ruin the look of your walls. But fixing a drywall crack is a DIY friendly task. Follow this step by step guide to get your walls back to new.

Tools needed

Before you start, gather the following tools and materials:

1. Utility Knife: For cutting and cleaning up the crack.
2. 6-inch Taping Knife: To apply and smooth the drywall compound.
3. Mud Pan: Not necessary but helpful for holding the drywall compound and to reduce mess.
4. Drywall Compound: Also known as joint compound, this is the one that fills the crack.
5. Fine-Grit Sandpaper: For smoothing the patched area after it dries.
6. Paper Drywall Tape: Recommended over fiberglass tape for a smoother finish.

Pro Tip: Don’t use substitute tools, it will make the process harder and will give you subpar results. Invest in the right tools from the start and you’ll save time and effort.

Step by Step Instructions to Fix a Drywall Crack

1. Prepare the Area

• Cut the crack using a utility knife to remove any loose or jagged edges. This will allow the repair material to adhere properly.
• Wipe the area with a damp cloth to remove dust and debris.

2. Apply Drywall Tape

• Cut a piece of paper drywall tape a little longer than the crack.
• Press the tape flat over the crack.
• Scoop some drywall compound into the mud pan.
• Use a 6-inch taping knife to spread a thin layer of compound over the tape. Feather the edges to blend with the surrounding wall.
• Let it dry. Depending on the product, this may take 24 hours.

3. Sand the surface

• Once the first layer is dry, sand the area with fine-grit sandpaper to smooth out any ridges or bumps.

4. Apply additional layers

• Apply a second layer, a little wider, of drywall compound. Feather the edges even more.
• Repeat the drying and sanding process. For deeper cracks, you may need a third layer to get a seamless finish.

5. Final Sanding and Finishing

• Once the last layer is dry, sand the area one more time until it’s smooth.
• Wipe away the dust with a damp cloth, then prime and paint the repaired area to match the rest of the wall.

Pro Tips

• Use light strokes with your taping knife to not overload the wall with compound.
• Always sand between layers.
• When painting, use a roller to blend the texture with the surrounding wall.

Mistakes to Avoid

1. Not sanding between layers. Each layer must be smooth before applying the next.
2. Using Fiberglass Tape. While durable, it’s harder to hide compared to paper tape.
3. Rushing the process. Let each layer dry before moving to the next step.
