Powder coating of reinforcement mesh

Powder paint allows you to protect any metal products. In particular, the grid. By adhering to the technology, the grid will be resistant to rust, ultraviolet, water and other influences. And this is a very valuable advantage. Especially if the painted grid is used for the fence.

In this article, we will talk about how easily it is to paint a mesh chain and what you need for this. 

Advantages of powder paint

First, powder paints are absolutely safe for health. They do not require solvents. Therefore, painters can work with them without fear. Powder-painted products are suitable even for installation in places where there are children.

And powder paint is very long in the coating. Therefore, painting the grid once, you can forget for a very long time that the coatings need to be updated regularly.

If you properly prepare the surface for painting, then the paint will lie very evenly. The coating will be strong and durable. How to prepare and how to process a mesh netting from rust, we will explain below. The powder-coated mesh is resistant to corrosion, quietly tolerates temperature fluctuations, constant UV radiation and does not deteriorate through rain.

The RAL color catalog is very large and varied. It provides the opportunity to bring to life a variety of ideas.

How to paint a mesh netting with powder paint

Powder painting consists of several very important steps. Initially, the surface is cleaned of oils, fats, dirt and rust. The sandblast is carefully treated with a net. Then the product should be degreased. This will remove residues of rust and fat. For degreasing there are special tools that are sprayed on the surface.

Then comes the stage of paint spraying. The principle of powder coating is that the particles of paint receive a charge and due to the electric field are settled on the product. To do this, you need to buy a gun. It can be tribostatic or electrostatic. The difference is how it charges the powder. In the first, the paint is charged due to the friction on its surface. And the second requires an external source.

In the case of nets it is better to use tribostatic. The fact is that it creates not such a strong electric field. Therefore, there is no risk of reverse ionization and the paint will normally settle in inaccessible areas.

The product for the application of paint is hung in the spraying chamber. All equipment and painters are grounded. Without it, the paint simply won’t settle on the grid.

After the product has been sprayed with powder, it is sent to the polymerization furnace. There is a coating.

Due to the specific design of the grid, its coloring can be accompanied by difficulties. Therefore, it is very important to follow all steps carefully, clean it thoroughly and check for grounding. If you can not solve the problems yourself, then you should seek the advice of specialists.

It is important to fit all the equipment to the size of the grid. It should fit completely inside the chamber and the oven. Otherwise nothing will work.

If you follow the guidelines of how to paint a welded mesh, then the coating will serve up to 20 years, and there will be no visible traces of operation.
