Helpful Tips:

  2. Never leave a foam dispensing gun without a can of adhesive attached unless it has been thoroughly cleaned with Great Stuff™ Foam Cleaner. 
  3. Flush the dispensing gun with Great Stuff™ Foam Cleaner before attaching another product. 
  4. Ensure all construction surfaces are clean and free of oils, dust and debris.
  5. Uniformly dispense a 1/2-inch bead of adhesive the full length of each stud or joist. Wherever sheet materials butt together along studs or joists, dispense two 1/2-inch beads side by side or one 1/2-inch bead in a zig-zag pattern the full length of the studs or joists.
  6. Tighten the flow control screw until fully closed for storage. Use can within 30 days of initial use.
