How to clean a foam gun

The assembly gun is an indispensable tool in construction. But what if it gets clogged? How to clean it from hardened foam?

Which polyurethane foam guns can be cleaned

The assembly gun is a tool for sealing cracks and holes with special foam, which requires special attention and care. Cleaning methods differ depending on the type of appliance.

The assembly gun is an irreplaceable assistant in construction

1. Metal. The most reliable and durable. Its term of work can be up to 5 years. It is easy to clean.
2. Teflon. It is of high quality. In it, the metal surfaces are protected with a Teflon coating. This makes it easy to clean. The foam removal scheme is the same as for a metal tool.
3. Plastic. Most often disposable, so it is impractical to clean it. If it does not run out of foam, then immediately after the end of work, its nozzle should be flushed with a solvent. This will prepare the device for further use.

It is important to clean up the plastic gun immediately after completing the work.

How to clean your instrument at home

There are special tools for cleaning the nailer. It is better to purchase them with the instrument. Moreover, the manufacturer of the foam and the product for its removal must be the same. Otherwise, the procedure for getting rid of the building material will be somewhat more complicated and take longer.

After finishing the workflow, follow these steps.

1. Remove the used foam canister from the device.
2. In its place, fix the cleaner with the cleaner, after removing the cap from it.
3. Press the trigger until no more foam comes out of the nozzle.

If a can of cleaner is not completely used up, close it with a protective cap and save it until next time.

We observe safety precautions

The solvent, like any chemical, is not very good for your health. When using a cylinder, basic safety measures should be observed:

• the nozzle should point downward when cleaning. This will prevent the solvent from getting in your eyes or on your clothing;
• keep the cylinder away from open flames, heating devices and direct sunlight;
• do not try to open or burn an empty container from the cleaner;
• do not smoke while using a solvent balloon;
• if liquid gets into eyes, consult a doctor immediately;
• in case of damage to open areas of the body, treat them with a solution of soda (1 teaspoon of soda in a glass of water at room temperature) or laundry soap, and then rinse thoroughly with water.

How to remove foam with acetone

If you do not have a special liquid, acetone can be used at home. Pour it into the nozzle of the tool and use a wire or cleaning rod to thoroughly clean the device. Care must be taken to avoid damaging delicate and vulnerable parts.

How to wash hardened foam

If the tool has not been cleaned immediately after use, the trigger must never be pulled before cleaning. The trigger mechanism may break. Here's how to properly clean the gun from cured polyurethane foam:

1. Clean the sticky foam from the barrel. You can use a knife. Be careful not to scratch the piston.
2. Lower the gun with the nozzle down and put Dimexidum into the trigger mechanism. After a minute, gently pull the trigger. If it starts to move and foam comes out of the nozzle, then the gun is ready to work. If this does not happen, then you need to go to the next stage of cleaning.
3. There is a small ball next to the cylinder screwing device. Apply a few drops of Dimexidum to it. After 5 minutes, attach the cleaner bottle. Smoothly pull the trigger.
4. If the previous methods fail, disassemble the tool. Holding it at the bottom of the socket, carefully unscrew the crown, then remove the valve. Place a chemical solvent or Dimexidum into the socket and all internal parts of the instrument. After 20 minutes, wipe off any remaining dirt with a cotton cloth. Then reassemble the gun and flush with solvent. After such cleaning, the device may generate less pressure during operation.

Is it possible to do without cleaning the nozzle

The assembly gun is an irreplaceable thing. At the same time, it has one drawback, so that the tool retains its properties, it must be cleaned after each use. However, there is a method to avoid this procedure and to keep the nozzle in good shape. To do this, you need a plastic tube used for a disposable instrument.

1. Prepare plastic tubing, wire and gun.
2. Attach the tubing to the nozzle using a wire.
3. After using the gun, the tube can be removed and a new one can be used later.

Each type of assembly gun requires its own approach. The main thing here is to prevent the foam from hardening inside the device. If you clean the tool on time, it will last you more than one year.
