- Helpful Tips
- Shake vigorously for a minimum of 60 seconds. If the can sputters, simply shake the can while held upside down.
- Any uncured product that gets on the skin can be removed with acetone.
- Best results if used when product temperature ranges from 60-90°F (15-32°C). The can should not be exposed to temperatures more than 120°F. Cured foam should not be exposed to temperatures in excess of 240°F.
- Firmly screw straw assembly onto valve and dispense SLOWLY.
- Mist with water to speed cure.
- Trim cured foam with serrated blade.
- If applied outdoors, be sure to paint or cover foam to prevent discoloration and UV damage.
If using GREAT STUFF PRO™ with the Foam Dispensing Gun, follow these additional steps before application:
- With the can secured, set your desired bead size by adjusting the flow control knob on the back of the gun (bead can be adjusted from 1/8"-3"). Then, pull the trigger to fill the gun with foam, dispensing excess foam into an appropriate waste receptacle. Lastly, test the bead size before applying.
- Tighten the flow control screw until fully closed for storage. Use can within 30 days of initial use.
- Store upright with a foam dispensing gun attached.
- Fill gaps <50%
- Always leave a can of foam attached to the gun with the flow control screw closed.
- When ready to change cans, shake the new can of foam for a minimum of 60 seconds.
- NEVER leave a gun without a can of adhesive without a can of Great Stuff Pro™ attached unless the gun has been thoroughly cleaned with Great Stuff™ Foam Cleaner.
