Surface Preparation:
For best results, all surfaces to be bonded must be clean, dry and free from dirt, dust, oil, loose paint,
wax or grease, etc.
Application Temperature:
For best results, the temperature of the adhesive and the surfaces being bonded should be between
60°-80°F (16°-27°C). Temperatures outside this range may affect bonding range and sprayability.
Equipment Setup:
Attach the larger flare fitting end to the spray applicator and tighten the nut securely. Check to see
that the applicator gun trigger stop/adjusting nut is fully locked against the trigger. Attach the other
end of the hose, a smaller flare fitting, to the cylinder valve and tighten securely.
Directions For Use:
1.) Slowly open the cylinder valve and inspect the connections for any leaks. Tighten if needed.
2.) Fully open the valve.
3.) Unscrew the trigger stop/adjusting nut away from the trigger 3-4 turns and spray a test pattern.
4.) Hold the applicator 3-10 inches away from the surface to be sprayed and apply a uniform coat of
5.) Apply 1-3 even coats of adhesive. (This will depend on the needed coverage for the bonding
6.) Allow adhesive to dry until tacky and then apply sufficient pressure to ensure complete contact.
Note: Test the tackiness by gently touching the adhesive with your knuckle. If the adhesive transfers
to your skin, it is too wet. If the adhesive is aggressively tacky and does not transfer to your skin, it is
ready to bond. If the adhesive is too dry or only has a very light tack, it is too dry and another coat of
adhesive should be applied to at least one of the surfaces.
For more adhesive output, continue to screw the nut away from the trigger. For less adhesive
output, screw the nut back towards the trigger.
adhesive. (The smaller the spray pattern chosen in step 3, the closer the applicator gun will need
to be to the surface and vice versa for larger patterns.)
