Application Tips:
Tongue & Groove Subfloor:
Use a 3/8” continuous bead on joists. Use ample bead of adhesive in all grooved
channels (remove excess squeezed out adhesive before it dries.) Panel joints
should not be tight. Allow 1/8” gap for expansion. Position and nail
or screw within 30 minutes. Proper installation methods for subfloorings
must be followed.
Decks:
Use 1/4” adhesive bead on every joist for additional strength
and to prevent squeaks. Nail planks at every other joist. Pre-drill nail holes.
