Water stained ceiling

Water stains on a ceiling can cause an unsightly focal point. Here you will learn how to cover it up for good.

Difficulty: Moderate

Instructions

Things You'll Need:

Primer
Paint
Painters Tape
Drop Cloth
Paint Brush or Paint Sponge
Paint Roller with handle

Step 1

The first step is to repair the leak. Locate the source of the water (leaky roof, condensation from piping, leaky pipe, etc.)and take the necessary action to ensure it won't come back. You don't want the stain to re-appear after you paint!
Step 2

Once the leak has been repaired, you need to make sure that the area to be painted is dried thoroughly. Allow a few days for the material to dry out on it's own. Attempting to dry a ceiling artificially (i.e. hair dryer) can cause the surface to 'shrink' and cause wrinkles. This can lead to replacing your ceiling rather than just re-painting.
Step 3

Apply Painters' Tape

There are a few things you'll need to do in preparation for your primer and paint application. Be sure to use a drop cloth to cover your floors and any furniture that would otherwise be exposed to paint spatter. Use painters tape or a high-grade masking tape to cover areas you don't want painted (i.e. crown molding, adjoining walls, light fixtures)
Step 4

Use a brush to paint around trim

Use a paint brush or paint sponge to apply primer to the areas that aren't easily reached with your paint roller. These would be next to the areas where you have applied your painters tape.
Step 5

Apply primer to the entire surface you are going to paint, ensuring the stain itself if thoroughly covered. Some primers come in a spray can while others need to be applied using a traditional paint brush or roller. Using a high quality primer is the key to making sure the stain won't show through your paint. Check out the article by Macdonald entitled 'How to Choose a Paint Primer.' This article will ensure you are using the correct primer for your application. Depending on the severity of the stain, you may need to apply a second coat of primer before moving on to step 5. Make sure you allow adequate drying time between applications.
Step 6

Paint Roller

Once your primer is completely dry, you can start painting. Use your paint brush or sponge and paint the areas next to your painters tape first. Remember, this is your final step and therefore, will be critical in the appearance of your finished product. Take your time and ensure you are using smooth strokes to reduce the look of brush marks. Once the trim paint has dried, use a paint roller to apply the paint to the rest of the ceiling. Try to use long, even strokes to ensure a smooth finish.
