2 70 ± 5°F and 50 ± 5 % RH, 1-inch bead diameter, 6-inch length. The cure rate is dependent on temperature, humidity, and size of the foam bead.

• Trim cured foam with a serrated blade.
• Any uncured product that gets on the skin can be removed with acetone.   
• If applied outdoors, be sure to paint or cover foam to prevent discoloration and UV damage.
• GREAT STUFF PRO™ Polyurethane Foams may be reused for up to 30 days when left attached to the applicator gun and when following proper storage procedures.                                         
• Shake can of GREAT STUFF PRO™ Pestblock vigorously for a minimum of 60 seconds. Tightly secure the can onto the gun before opening the valve to ensure that the can is properly threaded onto the gun basket to prevent leaks. 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.  
• For best results use 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.
• NEVER leave a gun without a can of Great Stuff Pro™ attached unless the gun has been thoroughly cleaned with Great Stuff™ Foam Cleaner.
• When applying Great Stuff™ Polyurethane Foam, make sure to wear PPE, including proper eye protection, gloves, and long sleeve clothing.
• Extinguish any open flames before applying foam
