How to Remove Mildew on Sheetrock
Sheetrock is an easy material to work with, but unless it is moisture-proof, it is vulnerable to water damage and mildew. When you notice mildew growing on sheetrock, it is important to take care of it right away. Once mildew begins to grow, the sheetrock can easily become weak and crumble. The steps below will show you how to get rid of it.
Remove the Moisture Source
The very first thing that you will need to do is find out what is causing the moisture that is leading to the development of mildew. If there is any sort of leak from pipes or from the roof of the building or home, this leak needs to be repaired. If the moisture is the result of condensation from a shower, ventilation must be installed in the room.
Prepare Bleach Solution and Ventilate Room
Add one part bleach to three parts water to a clean, plastic spray bottle. Before using this solution, open a window in the room affected by the mildew. It is important that you not breathe in the bleach vapors. Wear rubber gloves, a mask, and protective eyewear.
Spray the Bleach Solution
Dampen the area affected by mildew with the bleach solution and allow this area to dry. Then carefully rub the area with a rag or towel. Do not use a sponge or any item that may have been wet. You do not want to create more mildew by introducing more moisture into the area. If the mildew does not disappear with your first attempt, spray it again, allow it to dry, and rub with a dry rag.
Paint Over the Mildew Stain
Once you have gotten rid of the mildew stain, you may want to paint over the area. If you decide to do this, be sure that you use a primer or sealant underneath to prevent stains from forming. You can also choose mildew-resistant paints.
