Spray guns make painting work very easy. In this article, we will consider devices manufactured by the Czech company Hammer, their advantages and disadvantages, a model range, and also give several recommendations for the operation and maintenance of these devices.

Peculiarities

Hammer electric paint guns are reliable, ergonomic, functional and durable. The high quality of raw materials and installation, a variety of the model range and affordability complement a number of advantages of Czech spray guns.

Networked electrical models have a number of drawbacks due to the way they are powered . - the mobility of the device is limited by the availability of power outlets and the length of the cable, which creates certain inconveniences when working indoors, and even more so on the street.

It should also be noted that when using nozzles of large diameters, the degree of "spray" of the material is significantly increased.

Types and models

The range of offered devices is quite large. Here are the characteristics of the most popular models. For clarity, they are arranged in tables.

As can be seen from the data presented, almost all models can be classified as universal: the range of substances for spraying is very wide.

How to use?

There are a few simple rules to follow when using spray guns

• Before starting work, first prepare paint or other substance for spraying. Check the uniformity of the poured material, then dilute it to the required consistency. Excessive viscosity will interfere with the proper functioning of the instrument and may even lead to breakage.
• Check that the nozzle is suitable for the substance being sprayed.
• Do not forget about personal protective equipment: a mask (or respirator), gloves protect from the harmful effects of sprayed paint.
• Cover all foreign objects and surfaces with old newspaper or cloth so that you don't have to rub off stains after painting.
• Check the operation of the spray gun on an unnecessary sheet of paper or cardboard: the paint spot should be even, oval, without drips. If paint leaks, adjust pressure.
• For a good result, work in 2 steps: first apply the first coat and then walk perpendicular to it.
• Keep the nozzle at a distance of 15-25 cm from the surface to be painted: a decrease in this gap will lead to sagging, and an increase in this gap will increase paint loss from spray in the air.
• After completing the repair work, immediately and thoroughly flush the unit with a suitable solvent. If the paint hardens inside the device, it will turn out to be a waste of time and effort for you.

Handle your Hammer with care and will give you years of service.
