A paint brush is a common paint construction tool, which is a manual construction method that can finely apply paint to the surface that needs to be applied.

The following is the construction process of the paint brush:

1. Preparation Before the paint brush construction, you need to make preparations. First of all, it is necessary to confirm that the surface that needs to be constructed is clean, smooth, and free of debris such as grease and dust. Secondly, it is necessary to prepare the necessary paint, paint brushes and other auxiliary tools, such as covering paper, tape, etc.

2. Paint preparation Pour the prepared paint into a container, and add the appropriate amount of water or diluent as needed to prepare it to the viscosity suitable for construction. When deploying, attention should be paid to the color and texture of the paint to ensure that it meets the construction requirements.

3. Select the appropriate paint brush according to the size and shape of the surface that needs to be constructed. In general, a small area of the surface can be flat brush, while a large area of the surface needs to be rolled brush.

4. Paint brush Dip the paint brush into the prepared paint and gently wring it out so that the bristles are moderately damp. In the painting process, we should pay attention to grasp the appropriate strength and speed to ensure that the paint is evenly applied. If dripping or leakage occurs, it should be repaired in time.

5. Painting order Generally speaking, the order of painting is from top to bottom, from inside to outside. Before brushing, the corners and protruding parts should be handled first, and then the entire surface is brushed one by one.

6. Brushing times In order to ensure the thickness and quality of the coating, it is necessary to brush several times. There should be enough drying time between each brushing, and it is generally necessary to wait about 8-12 hours. The number of brushes depends on the need and the type of paint used.

7. Cleaning and maintenance After the painting is completed, it is necessary to clean the paint brush used in time and put it in a dry and ventilated place. The bristles should not touch any hard objects to avoid deformation or damage. Before the next use, it should be cleaned with water or detergent.

In short, although the construction process of the paint brush is simple, it needs to be carefully carried out. Only in the careful operation and good construction conditions, can achieve a good painting effect.
