When to Repair Wet Sheetrock
Many home repair specialists indicate that if the leak is small and was caught before damage could be done, it may be possible to repair the sheetrock. It is important that not only the sheetrock dry thoroughly but the insulation behind it also dry thoroughly, because the insulation could hold moisture against the drywall and lead to the growth of mold. Any tape that is affected by the moisture should be replaced, and any water stains that are present on the sheetrock should be primed and painted over. It is important to thoroughly check all over for the presence of mold.
When to Replace Wet Sheetrock
If mold is detected or if the wet sheetrock is sagging, it is important to replace it. At this point its structural integrity has been weakened, and there is no way to restore it. In this situation, it is important to take out all of the screws in the sheetrock and cut out the damaged portion of the material. The measurements of the damaged area should be measured so that a replacement piece can be cut. Once this piece is cut, it should be set into the wall using screws. To seal the seams of the drywall, use mud tape and sheetrock mud. To smooth the sheetrock mud, sand the area with fine grit sandpaper and a sander. Once the area is dried and sanded, the area can be painted.
