Blog Article

Drywall cracks can ruin the look of your walls, but don’t worry! Fixing them isn’t as hard as it seems. Whether you're dealing with small hairline cracks or more significant damage, this guide will walk you through the best way to fix drywall cracks step by step. By the end, your walls will look smooth and flawless again.

Why Do Drywall Cracks Appear?


Understanding why cracks happen can help you fix them better and even prevent new ones. Here are some common reasons:

1. House Settling


Over time, houses naturally shift and settle. These movements can create stress on the drywall, leading to cracks, especially near corners or door frames.

2. Temperature and Humidity Changes


Drywall expands and contracts with temperature and humidity changes. For example, hot summers and cold winters can cause this movement, resulting in cracks.

3. Poor Construction Practices


If the drywall wasn’t installed correctly, it might crack more easily. For instance, improper taping or using the wrong screws can weaken the structure.

4. Accidental Damage


Sometimes, cracks occur due to bumps, furniture scraping the wall, or heavy objects hitting it.

Tools and Materials You’ll Need


Before starting the repair, gather the following items:

  • Putty Knife: For spreading the joint compound.

  • Utility Knife: To clean and widen the crack if necessary.

  • Drywall Tape: Prevents the crack from reappearing.

  • Joint Compound (Spackle): A filler used to repair cracks.

  • Sandpaper (Fine Grit): For smoothing the surface.

  • Paintbrush and Roller: To repaint the repaired area.

  • Primer and Paint: Matches the rest of the wall for a seamless look.


Step-by-Step Instructions to Fix Drywall Cracks


Follow these easy steps to fix your drywall cracks effectively:

Step 1: Clean the Crack


Use a damp cloth to wipe away any dust or dirt. A clean surface ensures the joint compound sticks well.

Step 2: Widen the Crack


For small cracks, this step may not be necessary. For larger or jagged cracks, use a utility knife to make the crack slightly wider. This creates a better surface for the compound to adhere to.

Step 3: Apply Drywall Tape


Place drywall tape over the crack. Make sure it is centered and pressed firmly onto the wall. Use fiberglass tape for better strength on wider cracks.

Step 4: Add the First Layer of the Joint Compound


Using a putty knife, spread a thin layer of joint compound over the tape. Cover it completely and extend the compound slightly beyond the tape edges. Let it dry for about 24 hours.

Step 5: Sand the Surface


Once the compound is dry, sand it lightly using fine-grit sandpaper. This step smooths the surface and prepares it for the next layer.

Step 6: Repeat Layers of Compound and Sanding


Apply a second layer of joint compound, slightly wider than the first layer. Let it dry and sand again. Repeat this process until the repaired area is even with the wall.

Step 7: Prime and Paint


After sanding, apply a primer to the repaired area. Once the primer is dry, paint over it with matching wall paint. Use a roller for larger areas and a brush for corners or edges.

Pro Tips for Success



  • Work in Thin Layers: Thick layers of joint compound take longer to dry and may crack.

  • Be Patient: Allow each layer to dry completely before sanding or applying another layer.

  • Blend Paint Carefully: Use a small sample of your wall paint to ensure the repaired area matches perfectly.


Common Mistakes to Avoid


1. Skipping the Cleaning Step


If you don’t clean the crack, dust can prevent the joint compound from sticking, leading to a weak repair.

2. Using Too Much Compound at Once


Thick layers can shrink as they dry, creating more cracks. Always work in thin, even layers.

3. Skipping Primer


Painting directly over a joint compound can lead to uneven color. Always use a primer before painting.

FAQs


Q1. What is the best way to fix drywall cracks that keep coming back?


A: Using drywall tape and multiple layers of joint compound is the best way to fix drywall cracks permanently. For recurring cracks, consider hiring a professional to check for structural issues.

Q2. How can I prevent drywall cracks in the future?


A: To prevent cracks, control the humidity levels in your home, use quality materials during construction, and fix small cracks as soon as they appear.

Q3. Can I use regular spackle instead of joint compound?


A: While spackle is fine for small nail holes, joint compound is better for repairing cracks because it’s more durable and easier to work with over larger areas.

When Should You Call a Professional?


If you notice any of the following, it might be time to get professional help:

  • Cracks wider than 1/4 inch or those that run across large areas.

  • Cracks caused by water damage or structural issues.

  • Recurring cracks that reappear despite repeated repairs.


Professionals have the tools and expertise to fix these issues properly.

How to Maintain Your Walls After Repairs


After repairing drywall cracks, it’s essential to maintain your walls to keep them looking great:

  • Inspect Regularly: Check for new cracks or damage, especially after extreme weather.

  • Control Humidity: Use a dehumidifier to reduce moisture levels in the house.

  • Protect Your Walls: Avoid bumping furniture or heavy objects into the walls.


Conclusion


Repairing drywall cracks is easier than you think, and with a little effort, you can make your walls look brand new. By cleaning the crack, applying drywall tape, using joint compound, and finishing with paint, you’ll have smooth, flawless walls in no time.
