SURFACE PREPARATION

 

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. BY-SF can be applied at

temperatures as low as 10°F (-12°C).

 

APPLYING THE PRODUCT

 

Condition BY-SF 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.

PACKAGE:

BY-SF is available in 10fl.oz (296ml), 28fl.oz(828ml) cartridges, also can customze 1000ml foil pack, 24pcs in a carton.
