How to choose a paint brush?

1、 What should I pay attention to when choosing a paint brush?

1. Brush material

Generally speaking, the bristles of paint brushes are mainly made of materials such as pig bristles, nylon, polyester, etc. Among them, pig bristles have good water absorption and smooth painting, but they are relatively expensive; Nylon and polyester bristles have the advantages of good elasticity, no shedding, and relatively low prices.

2. Brush head shape

The shape of the paint brush head can be flat, angled, rounded, etc. The flat type is suitable for brushing large flat surfaces, the angled type is suitable for brushing corner lines, narrow spaces, etc., and the rounded type is suitable for brushing arcs, curves, etc.

3. Brush bristle density

The higher the bristle density, the greater the water absorption and the smoother the surface coating, but the brushing speed will be slower. Therefore, when choosing a paint brush, it is necessary to choose according to the actual situation.
