Application Tips

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

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

Subfloors: Conventional or tongue and groove: Lay one 1/4" (.64 cm) zigzag adhesive bead on each joist. On supporting joists where sheets meet, lay two zigzag beads 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 of all joists. Subfloor must be under roof within 6 weeks of construction. Proper installation methods for subflooring must be followed.

Decks: Use a 1/4" (.64 cm) bead 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.

Use mineral spirits or an adhesive remover.
