There are many types of paint brushes, which can be divided into flat brushes, round brushes and crooked neck brushes according to their shapes (Figure 6-1); according to their production materials, they can be divided into hard brushes and soft brushes. Made of Jie hair, soft brushes are often made of wolf hair, wool, etc.
In paint work, flat brushes are commonly used. Round brushes absorb more paint and are especially suited for modern high build high solids paints. The specifications of the flat brush are 1/2in (12. 5mm), 1in (25. 4mm), 1½in (38mm), 2in (50. 8mm), 2½in (66mm), 3in (76mm), 4in (101. 6mm), etc. Various.
The size of the brush used to paint the workpiece in hand should be selected. Using a small brush on a large area makes it difficult and slow to apply an even coating, while using a large brush on a small area makes fine work difficult.
To do this, dip the brush into the paint and, as you remove it, wipe or tap off the stinged paint on the side of the container. The brush allows the paint to flow over the surface in a smooth, even pattern, and do not use excessive pressure that may leave streaks or depressions in the painted surface. Apply the subsequent coat at right angles to the previous coat in a cross shape. This ensures complete, even coverage and helps close pinholes from previous coats. Applicators should maintain a "wet edge"' and move from the newly painted area to the front of the wet edge when brushing. This minimizes visible brush marks and overlapping areas.
