Excellent paint job is done only with the use of quality paint and a good paint brush. Before buying a paint brush make sure it's the right kind for the type of paint you are going to use. Latex brushes don't work well with oil paints, nor do oil brushes work with water-based paints. Once you have the right brush, you can start coloring your dreams.

You can either use paint from the paint can or pour some paint into a painting pail.

Dip the brush directly into the paint up to 1/3 of the length of the bristles. This stops the brush from being overloaded with paint and prevents dripping.

Tap both sides of the brush lightly against the side of the can or pail. This loads the paint more on the interior of the brush.

Do not scrape the paint off the brush by dragging across the edge of the can. That just removes the paint and makes the brush ineffective.

The more paint the brush carries, the faster you'll paint.

There is no tool in this world to replace paintbrush for "Cutting in" .Cutting in is a term used to describe painting the corners at walls and ceilings and around baseboards and door/window trim.

If you are right handed, cut in the wall at the ceiling corners from left to right. If left handed, paint right to left. This will give you visual control over how well the paint is flowing.

Press the brush against the wall just enough to flex the bristles and use the narrow edge of the paint brush when cutting in.

Convention has it that if the cut-in corner has two colors (wall / ceiling for example), then the lighter color paint would extend into the darker color area slightly and the darker color would be cut -in and painted on top of the lighter color. This way you don't have to worry about the lighter color not covering and reading the darker color underneath.
