How To Easily Fix Water Damaged Ceiling Plaster

Posted on: 18 November 2015

If the plaster in your ceiling has been damaged by water, you need to act quickly to fix the damaged. You don't want your ceiling falling in because you failed to repair the damaged area in a timely manner.

The Cause Of Water Damage To Ceiling Plaster

The most common cause of water damage to ceiling plaster is water has leaked in through your roof. It may have leaked into your house because you have a crack in your roof. Or, you may have some tiles loose on your roof. Or perhaps your gutters are blocked up, and all that moisture seeped through the walls and into your ceiling. 

Signs Of Water Damage

When water leaks into your ceiling, you will generally start to see bubbles on your ceiling. You may also see paint flaking off your ceiling. You may see or smell mold developing and your ceiling plaster may also change colors. It generally looks a little darker when it is stained with water. 

Stop The Water

The first thing you need to do is determine where the water is coming from and prevent additional water from leaking onto your ceiling. Take a trip up to your roof and pin-point where the water is coming and fix the problem. Or, hire a roofing contractor to come in, identify and fix the issue for you. 

Remove Loose Material

After you stop the water, you need to remove any loose material on your ceiling. You can remove paint flakes and loose plaster with a broad metal scraper. You'll want to gently scrap the material off. 

You should wear protective eyewear so you don't get any flakes in your eyes, and you may want to put on a mask as well. Place a drop cloth or plastic sheet under your work area so that you can easily clean up the mess that you make. 

Apply Primer

Once you have scraped away all the damaged material, apply a coat of primer to the area. Let it dry according to the directions on the package. Then, take your scraper and remove any debris that is still hanging around. Your ceiling should feel smooth by this point.

Apply Joint Compound

Next, you need to apply joint compound to your ceiling. You can use the same metal scraper you used previously to remove the debris from your ceiling to apply the joint compound and spread it out. Make sure that you spread it as evenly as possible.

Sand It Down

When the joint compound has dried, you'll want to sand down the joint compound so that you have a smooth surface. If you were careful when you applied the joint compound and spread it out evenly, you shouldn't have to do too much sanding. Wipe away any dust that is created with a damp rag or paper towel.

Repeat Then Paint

After you finish sanding it down, you should apply a second coat of primer and joint compound to your ceiling. This will ensure that your ceiling is strong. You can then paint your ceiling to match the rest of your house once it has a second coat of primer and joint compound applied to it. 

If you follow all of the steps outlined above, your ceiling should look like new with a few hours of work. Just make sure that you smooth it out and sand it down nicely after applying the joint compound in order to get a professional look to your do it yourself repair job.
