How to use a gun for sealant

Surprisingly, but the question is: how to use a gun for sealant sometimes, but still arises, especially this issue worries novice masters. And although this tool does not differ in the complexity of the design, but some people who first take it in their hands, it can even enter into a stupor.

Sealant gun - what is it?

If you look at the photos provided, how to use the gun for the sealant, you can generally understand what kind of tool and how to insert sealant into it. But the very principle of its work can present a certain complexity. After all, even his name is bewildering the layman. In fact, if you read the video instruction on the use of the sealant gun, you can understand why this tool is so called. It also has another name - a syringe.

This name it appeared because of its device and the principle of operation. The composition of the sealant is released from the plastic tube by pressing on a kind of trigger, so there was such an association with one of the types of firearms. There are several types of such tools and they can be divided into the following categories:

• by type of compartments into which the cartridge is inserted;
• on the features of the device;
• by the method of silicone feeding.

If you look at the pictures, you can pay attention that this tool can be of several types:

• battery;
• pneumatic;
• electric;
• mechanical.

Each pistol is designed so that it can seal the hard-to-reach gaps. The most common are mechanical tools, as they relate to the budget option.

How to use a syringe for extruding silicone?

It is worth watching the video on how to use a gun for sealant, and everything will become clear:

1. Before inserting the cartridge from the syringe, it is necessary to pull out the metal pin. For this, it is required to use two hands, since the pin itself will not stretch, because it is held by a special retainer. When you pull the trigger with one hand, the retainer releases the piston and can be pulled. But pull it is necessary to the very end.
2. Now you can insert the cartridge into the gun and fix it with a few clicks on the trigger. But do not tighten it strongly, because first you need to prepare the tip of the cartridge.
3. When the cartridge is fixed, the tip is cut off from it and the cone is threaded through which the silicone will be squeezed out. Cones come with both ready-made holes( one under the thread, and the second smaller - for the outlet of the sealant), and without one hole. If there is not a smaller hole, you need to gently cut the cone with a knife.
4. To see how the sealant gun works, press the trigger several times until the piston is fully seated in the cartridge. The tool is ready and you can start working.

The cone of the cartridge must be adjusted to the place that needs to be sealed. After that, you can click on the trigger, activating the pusher, which will evenly squeeze the sealant sausage of the required thickness. When the pusher will move, then the latch will work simultaneously, so that the piston does not relax its pressure on the bottom of the cartridge. To remove the used cartridge, pull the trigger to loosen the latch, pull out the pusher with the other hand and free the cartridge.
