How To Fix Water Stains on Your Ceiling
Unless the water has caused structural damage, it is fairly simple to seal a common water stain.
The first thing to do is to make sure that the ceiling is not soaked. If this is the case, then you may need to replace the drywall. This is because mold and mildew can form.
The next thing that needs to be done is to remove any loose paint. You can use a wire brush to do this. In addition to removing any loose paint, you need to clean the area with a household cleaner. If there is any mildew or mold, the area needs to be disinfected with cleaner, bleach, and water. It is very important to make sure that the mold is removed completely, so that it doesn’t have a chance to regrow.
Make sure that the area is totally dry before you prime. It is a good idea to use a hair dryer on the area for a small stain and a dehumidifier for bigger stains.
Before you prime, you need to apply a coat of shellac. After this, apply a high quality primer to seal the area. Finally, paint the area with the same color as the rest of the ceiling.
