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.
