If you want to paint indoor walls, you cannot merely collect paint brushes, rollers, and a pan or bucket and start working. Painting an interior requires preparation, knowing what paint to buy, and learning the correct painting method. For example, when painting walls, you do not want to begin toward the bottom. The correct approach is to work from the top down. Therefore, you should always begin close to the ceiling.
Never Paint a Wall with a Brush
When you paint a wall, do not use a brush. You will just leave brush marks on the wall. Instead, use a roller and a five-gallon bucket or roller pan. Do not stick the roller all the way into the container lest you cause a sizable mess. Instead, when you use a bucket, use a roller grid. Doing so will cause you to drip less paint. If you wish to use a pan, always insert a liner.
Loading the roller with paint should not be done with a dry roller. Instead, to load the paint onto the roller, dampen the tool first with a wet cloth. Dip the roller lightly into the paint and roll it onto the liner or grid a couple times to keep the amount of paint consistent.
Do Not Squeeze the Roller against the Wall
Now that you understand the correct way to load the paint, you can start working on the wall. Do not paint straight up and down when painting a wall. Instead, begin a few inches from the ceiling. Zig-zag the roller for better coverage. Also, do not squeeze the roller against the wall when you are painting. Simply reload the roller when you need more paint.
It is also not good to roll the paint over the wall at a quick pace. If you go too fast, you can miss some areas and create unsightly splatters. Always work in sections spaced about four feet apart. When you complete a section, go onto the next section of the wall.
Do paint the edges first when rolling the paint on the wall. Again, you want to start further down from the ceiling initially. After you get some paint on the wall, you can go along the edges. To roll the paint on effectively, turn the roller on the side to get close to a baseboard or ceiling.
Do not apply a lot of pressure when you are removing any runs or buildup. Instead, take the roller and lightly go over a section again from the ceiling to floor.
Do Not Paint All the Walls at Once
Do not paint all the walls in a room at the same time. Instead, you want to use an individualized approach. Paint each wall separately, applying two coats.
Should you need to take a break from your painting project, do not leave the bucket, pan, or tools uncovered. Cover the bucket with a lid and keep the paint from drying in a pan with plastic wrap. Also, use aluminum foil or plastic wrap to cover the roller and brushes.
Do not paint the trim without using blue painters tape along the edge. Take the tape and press it firmly with a putty knife. Proceed and paint the edge with a brush. Remove the tape soon after you paint the edge. Doing so will prevent problems with peeling. Do not try to pulling up the tape with force where it is stuck. Carefully use a knife instead.
