Is it possible to apply powder paint at home

It is possible to obtain high-quality and durable coating of metal products with powder paint. It is enough for many years, and no traces of exploitation on products are visible. The process of powder coating is quite laborious, but not complicated. And products can be used almost immediately after coating. But in case of liquid coating the can be used immediately. Let’s see if powder paint can be used at home.

The main thing about powder paint

Powder paint is a special dry powder with colored pigment. It is applied to the product by an electric charge: the powder particles are magnetized to the workpiece. The paint creates a uniform, durable coating under high temperatures.

Among the advantages of paint are its resistance to mechanical damage, moisture resistance, resistance to UV, no leaks and durability.

We also say about the disadvantages of powder. It is impossible to deviate from the coating technology, otherwise nothing good will work. There may be problems with preparing details for painting because of their features. Powder coating equipment has a fairly high cost, although the cost of powder coating is still cheaper than liquid.

Powder painting equipment

Due to the fact that the polymerization (solidification) of the paint requires a certain temperature, the powder coating can be applied with the help of special equipment.

These are spray gun, spray chamber and polymerization furnace.

Also, it requires special equipment to prepare the products for painting. Pre-treatment of metal requires sandblasting. It removes contamination from the surface. For small workloads, a small appliance is suitable.

It is necessary to have a spray gun. You can`t make powder paint gun with your own hands. You just need to buy it. And very important: liquid paint spray guns are not suitable for powder application. But the spraying chamber and the polymerization furnace, in principle, can be built by you. Although it will be quite troublesome.

If the spraying chamber is simple enough, this equipment is needed only to shield the painting area from another space.

Some knowledge in the field of electricity is required to construct a polymerization furnace. From the profile pipe you need to assemble the frame, the walls can be made of sheets of galvanized steel, the camera can be insulated with basalt or mineral wool. The heating must take place with the help of the fire-bar element. You also need to install automation that will adjust the heat. And of course, there should be a fan in the oven for forced air circulation.

Powder painting technology

Powder coating occurs in several stages. The first is preparation. It is very important to carefully remove any contamination and traces of the previous paint (if any). This is necessary in order for the powder to lie evenly on the surface.

After cleaning, the powder is applied to the product with a spray gun. The detail for high-quality spraying of paint is hung in a spraying chamber. Professional chambers have a recuperator. It collects particles of powder that have not settled on the product and sends it back to the gun. This powder can be reused.

After applying the powder to the product, it is sent to the polymerization furnace. There at a certain temperature the paint spreads and solidifies. The temperature required for this and the polymerization time are usually indicated on the paint packages.

Based on the above, we can conclude that powder paint with your own hands at home can in principle be applied. However, some equipment will still have to be purchased, and time will have to be spent on manufacturing other devices. But you should to do it only if there is necessity of regularly covering metal products. For one-time painting it is still easier and cheaper to ask specialists.
