If you are painting a room, chances are you need to paint the ceiling as well. A fresh coat of paint on the ceiling will help your room look brand new. In order for your ceiling to look its best after a new coat, it's important to choose the right ceiling paint, which usually isn't the same as your wall paint, even if it's the same colour.
Choose a Primer
It's best to prime your ceiling first and to use one with a stain blocker, such as Kilz Primer. Using primer first will disguise any discolourations due to water damage, for example, and will give you a neutral backdrop that will accurately display your chosen paint colour.
In general, flat paint is the ideal choice for painting ceilings. Flat, latex paint has no sheen and hides imperfections and blemishes well, dries more evenly and will hide roller marks better.
Ceiling Paint for Humid Rooms
When painting a bathroom, which tends to have more moisture in the air after showers or baths, it's best to choose a semigloss or glossy latex paint. The sheen in the paint helps the paint resist moisture and prevent ceiling damage.
For ceilings, it's best to roll the paint on in straight lines instead of a "W" pattern like on walls. This method helps hide any roller marks. It's also best to begin parallel and opposite to the room's entrance. Also, with each new line, blend it with the previous line by overlapping your paint about 6 inches. This method is especially useful for semigloss or glossy paints, which are more likely to show roller marks because of their sheen.
Useful Ceiling Paint Tools
It's easier and less stressful to paint a ceiling standing on 2 feet rather than on a ladder, so purchase a paint roller that will take an extension handle. If you are painting a textured ceiling, purchase a paint roller with a thick nap (at least 3/4 inch) so it will distribute paint evenly over the bumps.
