How to clean the gun for foam?

For the implementation of the construction work is very often used gun for foam. The mechanism of application of the device is very simple, so it is used by both professional masters and amateurs.

The gun allows you to accurately and accurately fill the seams with foam. But every tool needs care. This rule applies especially to a pistol, since a dried sealant may affect the operation of the tool.

Modern manufacturers of construction equipment offer a wide range of high-quality and convenient guns for working with assembly foam. The rules for cleaning this tool depend largely on its type.

To date, the following types of mounting guns are offered for sale:

• Plastic. They are considered to be disposable, since plastic is an unbearable material. This tool does not need to be cleaned. If the work on filling the seams is fully completed, and the foam in the cylinder still remains, then it is necessary to wipe the nozzle of the gun from the sealant residues, and in the future the gun with the cylinder can be used again.

• Metallic. They are characterized by durability and reliability. A quality metal pistol can be used for several years. This option can be easily disassembled for thorough cleaning of residual assembly foam.
• Teflon. This variety is the most durable, quality and expensive. Each metal part is protected by a Teflon coating. Cleaning such a gun is quite easy. The tool can be disassembled to clean it of sealant.

The mounting gun provides many advantages:

• produces an accurate dosage of foam;
• regulates sealant feed rate;
• allows to use foam even in places with limited access;

• enough to release the trigger to stop the flow of material;
• allows you to use only part of the container with a sealant, while you can be sure that the foam will not harden until the next time;
• If you use a gun every day, then there is no need to remove frozen material.

The peculiarity of the assembly gun mechanism is that in the pauses between work, it guarantees the complete protection of the sealant against the ingress of oxygen, therefore the foam is not prone to drying. The tightness of the alignment is due to the remnants of the foam, which remain at the end of the tube, and the tightness of the cylinder corresponds to the trigger mechanism in a closed form.

To get back to work, it is enough to cut the foam ball on the tool nozzle.

When choosing a quality gun for foam, you should focus on the material and price of the tool. Expensive options are characterized by a long service life. There is no need to buy a new tool every time, so an expensive gun easily pays for itself.

The term of use of the assembly gun depends on its service. After work inside the tool remains sealant.It will not damage the product if you quickly clean the nozzle, barrel, adapter and other elements of the mechanism.

It is not always possible at the end of the work to start cleaning the gun for foam; therefore many face hardened foam. In this case, its removal will take more time and effort.

Inexperienced masters do not always understand why they need to clean the gun, so they ignore this procedure. As a result, upon further application, it ceases to work, because the foam has dried and the trunk has clogged up. The tool requires cleaning if the repair and construction work is already completed.. Next time it will be ready for use.

If you need to seal the seams with foam once, then there is no need to spend money on the purchase of a pistol, then you can do well only with a sealant cylinder with a special applicator.

According to experience, even home craftsmen prefer pistols, since they will have to use more than once.

So that the gun is always ready for operation, ideally it should be rinsed after each use. Experts recommend washing the instrument, even if you plan to change the sealant bottle from one manufacturer to another., or want to use foam other heat resistance.

Typically, materials from different companies have different impurities in the composition, and if they come into contact, they can turn into a mixture that no cleaner can help to eliminate. The tool will have to throw.

When buying a sealant, you should immediately purchase a cleaner so that they are from the same manufacturer. This approach will allow the gun to be cleaned quickly and easily, since the company has manufactured the most effective personal sealant cleaner.

In reality, it is not always at hand that there is a cleaner or free time for washing the instrument, therefore, the gun is usually flushed at the end of the working day.

If there is no special tool for cleaning the tool from the foam, then you can use the improvised means.

To make a high-quality cleaning of the foam gun, you must perform the following sequence of actions:

• It is necessary to remove an empty sealant bottle from the gun, and the tool should be located at the top.
• To clean the instrument, you need a special bottle with cleaner.
• The flushing agent must be fixed in the same place where the sealant was located, but before using it you must remove the cap from it.

• It is necessary to bring the gun in working condition, with the cylinder with a cleaner will be located at the top.
• Gently pull the trigger of the gun, continue this action until no more foam escapes from the tool nozzle.
• Remove chemical bottle.
• If after cleaning the tool is not finished, then it should be closed with a lid, and you can use the composition for the next cleaning tool.

If it was not possible to clean the gun immediately after the end of work, then before cleaning it is prohibited to press the trigger of the tool, because this can break the whole mechanism.

You must perform the following steps:

• Using a sharp object to remove the remnants of frozen foam from the tool barrel.
• Rinse the gun can be using "Dimexidum" or acetone.
• The nozzle should be lowered with the nozzle down, and a few drops of solvent should be dropped into the trigger mechanism.
• Leave the instrument in this position for one minute so that the foam inside the instrument starts to soften.

• Easy to pull the trigger.
• If it is pressed gently and the foam comes out of the nozzle, this means that the agent has worked and the gun can be used for work.
• If the sealant does not appear from the nozzle, then you need to drop a few drops of the cleaner on the ball, located in the device adapter.
• After five minutes, fasten the cleaner bottle and gently pull the trigger.

If the above methods of cleaning the gun did not help to eliminate the frozen foam, then it remains only to disassemble the tool:

• it must be held below the nest;
• unscrew the crown first;
• remove the valve;
• drip the cleaner into the socket and onto the remaining internal parts of the instrument;

• leave in this state for 20 minutes;
• using cotton cloth to remove foam;
• then you need to collect the tool;
• wash with solvent.

If after the end of work with the gun more than six hours have passed, then you can immediately proceed to the mechanical method of cleaning, because during this time the sealant hardens tightly inside, so normal washing can not cope with the task.

Foam gun requires special care. If you do not regularly clean it after use, it will stop working. To wash this tool does not take much time, the procedure itself will take no more than 20 minutes, so you should not be lazy, because the working condition of the device depends on it.

If you clean the gun for foam at home yourself, then you need to follow safety instructions. Remember that solvent is a chemical, so it can harm human health.

Basic safety measures when cleaning the foam gun:

• The nozzle should always be directed downwards, as this will eliminate the possibility of the cleaner getting on open areas of the body, eyes or clothing.
• The solvent tank or foam must always be kept away from direct sunlight, heating appliances and open flame.
• The used container from the solvent must not be burned.
• Do not smoke while rinsing the gun.

• All work is desirable to carry out protective gloves and glasses.
• If the liquid gets into your eyes, you should immediately contact your doctor.
• If the solvent gets on the skin, it is necessary to treat the affected area with a special solution (one teaspoon of soda per 200 ml of warm water) or wash the solution with household soap under a strong stream of water.
