• Mist with water to speed cure.
• Trim cured foam with serrated blade.
• Any uncured product that gets on the skin can be removed with acetone.
• Shake vigorously for a minimum of 60 seconds. If the can sputters, simply shake the can while held upside down.
• 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.

Great Stuff™ cans featuring the Smart Dispenser™ may be reused up to 30 days with the straw left attached to the canister, just clean the tip after your first use. For best results:

• Do not unwind the dispenser after you have started using it.
• Let up on the trigger slowly to release pressure in the straw and prevent spurts during the next use and to achieve the most consistent bead.
• Tighten the flow control screw until fully closed for storage. Use can within 30 days of initial use.
• Store upright with dispenser still attached to can.

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.
• 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.
