Painting a room is a job for which you need time and patience. It is not a job you can rush if you want to have a smooth finish to the walls. One coat of paint must be completely dry before you can start applying the second coat. If you use an emulsion paint you won’t have to wait too long because this type of paint dries very quickly. It is important to check the label on the can to read the manufacturer’s instructions on the paint to find out the drying time.
The finish you want on the wall will determine the type of painting tools that you use. If you want to achieve a smooth finish, you should use a brush, a paint pad or a foam roller. If you want a deep or rough texture, choose a brush that has shaggy pile. Whatever type of painting tool you use for the main area of the walls you will still need a small brush for painting around the woodwork and for cutting in around the edges of the walls and ceilings.
The widest brush you can find is the best one to choose for painting walls. It must also be comfortable for you to hold in your hand when doing the job. Start at the top of the wall and run bands of paint down the wall in vertical strips. Leave a small gap between the strips. Once you paint several strips, brush across them to blend the paint using light vertical strokes.
If you are using a roller or pad, fill the tray with paint. Roll it back and forth so that it is filled with paint and then start painting the wall. Start at the top, just as you do with the brush, and paint a strip down the wall, but angle it slightly. As you paint the next strip, lap over the edges of the previous strip of paint to blend the paint strips together on the wall. Paint a small area at one time and don’t roll too quickly because this will cause the paint to spray off the roller, giving you a mess to clean up.
A paint pad should be used in a crisscross motion. A pad does not apply a very thick coat of paint, which means you will have to repeat the process several times to cover the wall.
It is a lot easier to cover a light color paint with a darker color, but you will still need to apply two coats of paint. Applying a lighter color over a darker color may require three or more coats to make sure that none of the undercoat shows through.
