You notice a darker spot on your wall or ceiling and determine that it is the result of water damage. If you decide to repair the drywall yourself, you should check out some of the most serious mistakes which are commonly made and how to avoid them. Let’s begin.
Missing to eliminate the underlying cause of the problem.
You fix the drywall and forget about it only to discover that the water damage is back on just a few weeks or months later. Avoid this mistake by getting down to the cause of the problem as soon as you discover it. Most often, the water damage is the result of a roof leak so roof repair will be needed too. Problems with the pipes are equally serious and should be dealt with right away.
Ignoring mold or remediating it in the wrong way.
Keep in mind that even if you remove the portion of drywall where mold has grown, it may continue to spread afterwards. That is why the affected area should get a mold treatment just to be on the safe side. Additionally, some types of mold such as black mold are extremely dangerous and should only be handled and removed by specialists.
Removing only a portion of the affected drywall.
The rule of thumb which you must follow to avoid making this grave mistake is to cut out an area which is slightly larger than the section which seems affected by water. If the sides of the hole, which should ideally have rectangular shape if it is large, feel damp to touch, cut small sections of them until you feel a completely dry surface. One of the best tools to use for this job is a keyhole saw.
It may go without saying, but if an entire drywall panel is soaked with water, it must be removed. This is one job which is better left to professionals primarily for safety reasons. Generally, when you do any kind of big drywall repair job, you should wear a protective mask, goggles and gloves to be on the safe side.
Not installing replacement pieces of drywall properly.
It’s a bit challenging to cut pieces of the correct size, but it is always best to make them slightly larger and use a knife to trim them. If the piece is considerably smaller than the hole, the cement adhesive may not be able to hold it firmly in place and you may be forced to fix the drywall soon after the initial repair. When fitting a piece of replacement drywall, you should do it at an angle to save time and effort and to avoid damage to the surrounding material.
Applying joint compound incorrectly.
Usually, one layer of joint compound isn’t sufficient for restoring and leveling drywall patches. In this case, you should apply two or three to get the best result. The key thing is to leave each layer to dry fully before you apply the next one. Otherwise, it may begin to crumble.
If your drywall is heavily damaged by water or you aren’t sure that you can repair it properly, use a professional service.
