must be clean, dry, and free of dust.

Application

Use a caulking-type gun. Apply 1/4" minimum round bead of sealant (5/8" maximum) to seal perimeter of sound-rated

partition. Seal sound-rated partitions on both sides where facings abut dissimilar materials: around perimeter; in the
angle formed by panels and abutting dissimilar materials; at all intersections; at all panel terminations in door and
window frames; and at control joint locations before attaching the control joint to the panels. Apply continuous beads
of sealant around all openings formed for outlets, lights, etc. Completely butter the outside of electrical boxes. Cut
