How To Repair Drywall Cracks?
There are two main methods used to repair cracked drywall. One method involves using joint compound and taping over the crack. The second method uses patching material and filling the crack with mud. Patching materials include fiberglass mesh, plastic sheeting, and even cement.
Repairing cracked drywall is a simple project that anyone can do. First, remove any loose plaster or paint from the area where the crack occurs. Then, apply joint compound along the edges of the crack. Next, tape over the crack with painter’s tape. Finally, smooth the surface with a damp sponge. Allow the drywall compound drying completely before painting the area.
Once the crack is patched, you can either sand down the patch or leave it alone. Sanding the patch makes it look less noticeable, whereas leaving it alone allows the patch to blend in with the surrounding drywall.
Small Cracks
The first thing to check when repairing small cracks is the location of the crack itself. Is it near a window or door frame? If so, make sure that the crack does not extend past the edge of the framing member.
This would cause the crack to open up and allow moisture to enter the wall surface.
Cracks that are smaller than 1/4 inch (6 mm) in width should be repaired using drywall patch kits and tacking strips. Tack strips are available at hardware stores.
They have several styles of drywall tape in different sizes and shapes. You can choose one that matches the shape of the crack.
Apply a thin layer of drywall mud along the edge of the crack. Smooth the joint sealer with a wet rag and remove all loose material. Let the joint sealer dry completely before applying more coats.
Apply several layers of drywall mud until the crack is covered. Once the joint compound has dried, sand the area lightly with fine-grit sandpaper or strip of drywall tape.
This will help make the patch blend in with the rest of the wall surface.
Large Cracks
Large cracks require patching material. There are many types of patching material available for repairing large common drywall cracks. Some common ones include:
Fiberglass Mesh – Fiberglass mesh comes in various thicknesses. Choose the right size piece of drywall based on the size of the crack. Apply the patching material to the crack by pressing it into place.
Plastic Sheeting – Plastic sheeting is also known as “plasterboard.” It is made up of multiple sheets of plastic laminated together. Cut the plastic sheeting to fit the crack. Press the patching material into the crack.
Cement – Cement is a good choice if you want to fill a larger crack. Mix up some cement according to the manufacturer’s instructions. Pour the mixture into the crack and let it set. Remove the excess cement with a damp cloth.
Patching Material vs Joint Compound
Joint compound and patching material both work well for repairing small and large cracks. However, there are differences between them. Joint compound ( also known as drywall mud) is typically thicker than patching material. Therefore, it takes longer to dry. If you need to wait for the compound to dry before painting, then use joint compound. Otherwise, use patching material.
If you’re unsure which method to use, ask your contractor for drywall repair professional. He or she will know which method works best in your situation and have drywall patch kits.
What Causes Drywall Cracking?
Cracked drywall is usually due to foundation settling or framing deterioration (such as rotting or being eaten away by wood destroying insects). These types of issues should be addressed right away.
However, there are times when drywall cracking is simply a seasonal issue. For instance, during winter months, temperatures drop below freezing and moisture freezes inside walls.
As a result, water expands and causes the drywall crack. Once the weather warms up, the frozen water thaws out and dries out the wall. This process repeats itself throughout the year until the wall is repaired.
How Can You Tell Whether A Crack Is Structural?
While you may not notice small cracks in your home’s exterior, they can become quite noticeable once they reach a certain size. If you see any signs of drywall cracking on your home’s interior, it is best to call a professional for help.
A structural crack will affect the integrity of your home and pose serious safety risks. It could lead to collapse if not fixed properly.
A structural crack is typically caused by a major problem such as a leaky roof or faulty plumbing. However, it can also occur because of normal wear and tear.
You can tell whether a crack is structural by checking for signs of movement. A crack that moves or shifts is most likely structural. If the crack does not move, then it is probably due to seasonal changes.
Next, look for large, jagged cracks. These cracks are typically caused by water infiltration into the wall surface.
They can sometimes grow over time. In some cases, the source of the water can actually be seen coming from outside the house.
If you notice any of these signs, contact a professional immediately.
Can Cracked Drywall Be Repaired?
Yes! Repairing cracked drywall is easy. All you need is a few basic tools and supplies.
First, remove all loose debris and dust from around the area where the crack occurs. Next, use a utility knife to cut through the damaged section.
Once this is done, apply a thin layer of joint compound along the edges of the hole. Use a putty knife to smooth out the compound so it covers the entire surface.
Allow the compound to dry completely before applying another coat. The final step involves sanding down the compound to achieve a smooth finish.
When the compound is dry, paint over the topcoat using an appropriate primer and paint color. Allow the paint to dry thoroughly before moving on to the next step.
How To Prevent Drywall Cracking?
Preventing drywall cracking begins with proper installation. Make sure that the studs are well-anchored to the foundation. Also, make sure that the walls are plumb.
In addition, install exterior grade drywall instead of interior grade. This will help prevent moisture penetration.
Finally, keep the temperature inside your home at 68 degrees Fahrenheit or lower. Moisture expands when temperatures rise above 70 degrees.
