To Brush dip in paint to master the line: not only in the wall brush as much paint, but also to avoid the paint in the painting process will drip to the floor and your body. This technique can be learned in a few minutes, and the key is to accurately control the amount of paint that the brush holds.
Specifically, wet the bristles before starting the brush (latex paint is diluted with water, and other types of paint are diluted with a corresponding thinner) , adapting the brush to the paint and painting it more efficiently. Gently tap the metal plate around the handle of the brush on the palm, allowing excess water to flow into the sink or bucket. For the first dip, turn the brush slightly in the paint so that the bristles open and absorb the paint. Gently push the brush into the paint each time you dip it, making it easier to dip the brush into the paint. For most latex paints, just dip the brush into the paint, then lift the brush and wait a few seconds for the excess paint to drip off and then paint the wall with it. But with thinner paint, you may need to tap the inside of the can with a brush, or drag the brush through the inner edge of the CAN opening to remove excess paint.
