While every homeowner knows how to patch a large hole in drywall, few have a clue how to go about patching drywall that has been damaged by water. Drywall can be damaged by water running into it or because of mold and mildew growing within the drywall while it is drying. Fortunately, there are many repair techniques available for repairing drywall if it is damaged.
How to patch a large hole in drywall?
One of the most common ways to repair large holes in drywall is called hanging the patch. This involves getting a screwdriver and a drywall knife together and slowly moving the joint compound part of the drywall along the hole. The compound will be squeezed between the two pieces of drywall. This should be done in small areas until the wallboard begins to slide in place. Be sure not to leave a gap between the two parts of drywall.
Another method of repairing the drywall patch is called snapping back. This technique requires a little more work, but it is often easier. In this method, you will need to find a long piece of drywall that is straight and vertical. You will then take the drywall patch and attach it to the wall using the small stud puller that comes with some joint compound. Snap the patch back gently as you pull it to create a smooth joint.
If the drywall is damaged by water, you may need to add extra joint compound or sand the patch down prior to applying the new patch. If the damage is extensive, you may want to replace the entire patch. For larger holes, this may be a difficult task, but if the damage is extensive it may be necessary to replace the entire joint compound or the entire patch.
Some homeowners choose to build a retaining wall around a damaged hole in drywall. In this case, the drywall patch is actually added to the damaged drywall diagonally. This allows you to simply add the new drywall patch diagonally to the end of the existing drywall. The key to this type of patching is to use the correct size joint compound and install the patch in a way that leaves no gap for water to enter. Be sure to put a piece of board under the patch in order to avoid water penetrating the drywall.
In some cases, you may need to cut out sections of drywall in order to patch a hole. To do this, you will first need to find some good drywall strapping. If you can’t find any, you can purchase plastic pieces with small holes drilled in them.
Once you have your drywall patching ready, you will need to prepare the area that needs to be patched. Using a mask, cover the area that needs to be patched with tape. You will need to patch this area while it is wet; otherwise, mold and mildew may form. Once the area has dried, apply the joint compound on the patching and then push the patching into place. Once you are satisfied with the patching, apply some more masking tape to seal the patch in.
Installing a large drywall patch is not very difficult. When done correctly, the finished project will look similar to the original drywall. How to patch a large drywall patch is also very simple. When you have decided where to patch a large drywall patch, you should also have some helpful hints on how to complete the installation. It’s just a matter of using the right tools and techniques.
One thing that many people do not realize when doing large drywall patch jobs is that it is much better to use an electric sander than a regular sander. Electric sander’s are made for patching larger drywall sections and they are much more efficient than the regular sander. Even if you are using an electric sander, it is important to wear safety glasses. When conducting the patching job, always work from the opposite side of the wall. This will prevent you from inadvertently scratching the wall or other areas.
Once you have located the proper spot, you can begin to patch the drywall. To begin, make sure the area is clean and all the joint compounds are completely dry. If there is any oil or water, you will need to either wipe it away or use a special solvent cleaner to remove it. Patch the drywall in large sections at a time, working from the outside inwards.
Make sure that when you patch a large area that the drywall on the opposite side is also fixed. You may need to use stapling if there are any nails in the drywall. Once the patching is completed, if you have joint compound, use it to repair the area around the patched area. Apply another layer of joint compound to ensure the drywall has adequate adhesion.
