Foam gun: features of choice

Foam gun is a special tool that allows you to make installation work with great convenience . In particular, it is able to accurately dose the protective solution, filling them with very hard to reach places. Today, there are many different models of foam guns. Their design is quite simple.

Foam mounting gun is a tube with valves at its ends. To make it more convenient to work, the rod is equipped with a special handle and the mechanism of the exhaust valve, which is actuated by a trigger.

When choosing a gun, the following criteria must be taken into account. First, all parts of the instrument must be made of metal. Serious companies can perform certain elements from plastic, but in this case it is better to purchase only branded devices. If the foam gun is manufactured by an unknown company, moreover, it has many plastic parts in its design, then it is better not to buy such a product at all. The choice of such tools is quite wide: the products of the brands "Workman", "Zubr" proved to be very good. These devices, despite the cheapness (about 500 rubles), can spray a few hundred cylinders.

It's good if the foam gun has a removable design. In this case, it can be disassembled into parts, washed or replaced by a broken or worn out assembly. Particular attention should be paid to the quality of the valves in the device. However, they can only be checked during operation. Do this as follows. Take the tank with acetone and wind it on the gun. After making several keystrokes (to fill the acetone tube of the gun), the balloon is removed, and the device is left for several days without action. After that, when pressing from the outlet valve, acetone must escape, which was kept under pressure all this time.

In case this did not happen, and the gas evaporated during these days, and the pressure was on, then such a foam gun will not perform the mounting function, and it must be carried back to the seller for exchange. It will be inconvenient to work with such a device, it will All the time to wash, even after small breaks. Therefore, when buying a device, you need to keep a cash receipt.

This tool requires proper care and maintenance. Before starting work, it is recommended to spray the place of application of the substance with water, since moisture is necessary for its solidification. When using foam, it is necessary to take into account the coefficient of its expansion. Therefore, the cavity should be filled by a quarter. It is necessary to fix the parts that can be displaced by the expansion of the foam.

Foam gun has another good feature: a wound balloon can stay on the device for a long time. At the same time he is ready at any moment to work. However, do not leave an empty canister on the gun. It is better to remove it and blow the device. If you do not have the right substance at hand, you can flush the foam gun with a spilling acetone, having previously disassembled the device.
