Now it's all sprayed with a gun, and the effect of the roller and brush painting can't keep up with the requirements!

The advantage of the brush is that it is easy to operate, suitable for small area, complex structure objects, such as furniture, etc., the disadvantage is low efficiency, large paint consumption, high labor cost, easy to produce brush marks, etc., and at the same time to choose a better quality brush to prevent hair loss.

The advantage of the drum is that it is easy to operate, and it is suitable for objects with large areas or flat surfaces, such as the ground, walls, etc., and the disadvantage is that it cannot construct objects with complex structures. At the same time, it is also necessary to choose a suitable roller, such as water-based and oil-based materials, and the rollers used are different.

Summary. There are three methods of grinding: dry grinding, wet grinding, and mechanical grinding. Dry sanding:

Sandpaper is used for sanding. It is suitable for grinding hard and brittle lacquers, and its disadvantage is that a lot of dust will be generated during operation, which will affect environmental hygiene. Wet sanding:

Sandwork with sandpaper dipped in water or soapy water. Water grinding can reduce wear marks, improve the smoothness of the coating, and save sandpaper and labor. However, after the water mill, attention should be paid to spraying the lower layer of paint, one is to wait for the water mill layer to completely dry before applying the lower layer of paint, otherwise the paint layer is easy to white.

In addition, the substrate with strong water absorption is not suitable for water grinding. Mechanical grinding: In order to improve work efficiency during large-area construction, mechanical grinding methods can be used, such as electric grinders (disc type, vibrating type).

Why do you need to use grinding tools for paint painting, and what are the types of it?

Because it is more efficient to use grinding tools, and the discharge will be better.

1. Choose a good tool for painting: First of all, choose a tool according to the paint. If you want to paint the floor, you need to use tools such as black buckets, hammers, scrapers, rags, large and small paint brushes, and oil roller brushes.

If the wall is painted, in addition to brushes and scrapers, sanding tools should also be used to help deal with the unevenness of the wall.

2. Choose high-quality tools: Although paint construction tools are only auxiliary tools for painting, the quality of auxiliary tools is not good, and it is easy to affect the quality of paint painting. Therefore, it is crucial to choose a high-quality tool.

Take brushes as an example, if the material of the brush is not good, it is easy to lose hair in the process of painting and even dismantle until the paint is cracked.

3. Choose the number of tools on demand: There are many kinds of tools for decoration and painting, but not all the tools need to be used every time you paint them. When you buy tools, you should consider which tools you want to use, and try not to choose tools that you don't need to avoid wasting resources.
