Is adhesive starting to seep from your gun, after you have finished your application? Here’s a 3 point checklist to stop this from happening;

1. Check the hose connection to the gun. Does your hose look like a swivel hose?

If so, it is too loose and needs tightening. The gun and hose are designed to join almost seamlessly together. This is to provide the adhesive with a straight, unbroken trajectory to the gun tip. Any breaks in this line will mean the adhesive will leak out.

2. Take a look at the Gun tip.

Over time, the gun tips can build up with dried adhesive. When this happens, the gun can’t close off properly, so the adhesive continues to dribble out after the trigger is released. To fix this, simply remove the gun tip and clean with TensorGrip C101. In extreme cases, a replacement tip may be required.

3. Tighten the backing seal.

The adhesive only passes through a very small part of the gun when being sprayed. To prevent the adhesive from leaking out of this area, it is sealed off. This seal is held in place by a nut. Over time, this can become loose, causing the seal to fall out of place. This needs to be tightened. However, be careful not to make this to tight, as it will mean the trigger will not work, and the adhesive won’t spray as it should. 

If you have double checked each of these things, and your gun is still leaking, take a note of where it is leaking from, or take a photo and get in touch with us as soon as you can.
