In the process of spraying materials, spray foam gun is essential. The spray foam gun needs to mix the material quickly during the spraying process, which needs to be done at a very fast speed, because the bonded material begins to harden immediately. Therefore, no material can be retained in the foam gun for a long time. Excess material needs to be removed from the spray foam gun during the purging process.

Features of spray gun foam
Spray foam guns are important to the process of applying sprayed materials. They can mix the materials during the spraying process, which ensures high efficiency and prevents the combined materials from hardening due to remaining in the spray foam gun for a long time.

Tips of spray foam gun
If you take care of it, it is a good tool. Follow the tips below:
-Protect the tip. Do not damage it. If you do not protect it carefully, it will begin to clog or leak.
-Wipe the tip after using. Avoid foam on the tip.
-If you use this upside down (can facing down) it will work for about 3 seconds and then start spraying gas only. This will make the can last a lot shorter and you will cause it to dribble and make it a pain in the butt to use.

Spray foam gun common fault and solutions
-Air bubbles appear in the gun pot
Cause 1：Spray gun nozzle set is not tightly installed
Result: Air enters the paint channel and bubbles appear in the gun pot when spraying.
Solution: Tighten the nozzle.

Cause 2: Blockage behind the nozzle
Result: Paint residue prevents the nozzle from sealing 100% with the air diverter ring.
Solution: Clean the nozzle carefully.

Cause 3: Damage to the surface of the air diverter ring
Result: Air entered the paint channel due to improper disassembly.
Solution: Replace the air diverter ring.

Cause 4: Clogging of gun pot venting hole
Result: Due to the vacuum, air will be sucked into the paint channel and bubbles will appear first and then the paint will leak.
Solution: Clean the gun pot vent hole and replace the gun pot if necessary.
