Surface Preparation

Make sure that all surfaces are clean, structurally sound and free of excess water before applying this construction adhesive. Wood can be damp, but the construction adhesive will take longer to dry. LN-602 construction adhesive can be applied at temperatures as low as 10°F (-12°C).

Product Application

Condition LN-602 construction adhesive to at least 40°F (4°C) for easier gunning. Adhere materials within 15 minutes of gunning construction adhesive. Make sure skin of bead is broken. If it's not, scrape off bead and apply fresh bead of construction adhesive.


Use a 1/4" (.64 cm) bead of construction adhesive on every joist for added strength and to prevent squeaking. Nail planks at every other joist. Pre-drill nail holes to prevent splitting of wood.


Conventional or tongue and groove: Lay one 1/4" (.64 cm) zig-zag bead of construction adhesive on each joist. On supporting joists where sheets meet, lay two zig-zag beads of construction adhesive for added strength and to prevent squeaking. Space joints the thickness of a putty knife to allow for expansion. Nail section into place with 8d annular or spiral nails 12" (30 cm) on center on all joists. Subfloor must be under roof within 6 weeks of construction. Proper installation methods for subflooring must be followed.


Use mineral spirits to clean up both wet and dry construction adhesive.
