Precautions When Painting Stainless Steel Plates

 When painting the surface of the stainless steel plate, the details do well to get a good quality stainless steel plate. So what are the precautions when painting stainless steel plates? Let's take a look.

1. Basic treatment. If you want the film to be firm in the future, we must clean the surface of the stainless steel plate. We can use a knife to remove the original residual paint or sand the surface with sandpaper. It is easy to use sandblasting to make the surface rough and increase the adhesion area of the primer.

2. Spray primer. The function of primer is to prevent oxidation of the metal surface, and connect the topcoat and metal firmly .

3. Top coat. On the one hand, the paint film is required to have good weather resistance in the open air, on the other hand, it is extremely difficult to use a baking paint with a strong paint film. Therefore, it is recommended to use polyurethane paint, which is a two-component paint with a curing agent, without baking. The curing agent can be cured completely at ordinary temperature.

4. Whether it is spraying or brushing any kind of paint, the application should be divided into 3-5 times, and it should not be too thick each time, and then apply again after the previous drying.
