COMMON GLUE-ASSIST APPLICATION AND METHODS:
SERPENTINE (SINE WAVE) PATTERN

Serpentine (sine wave) pattern: The serpentine (sine wave) pattern, where the full curve (peak-
to-peak) is performed approximately twice the width of the board. The adhesive should cover the
entire length and width of each board.
PARALLEL STRIPES PATTERN

Parallel stripes pattern: The parallel stripes may run perpendicular to, or diagonal to, the length of
each plank being installed. Each stripe should be placed at approximately 6"– 8" intervals.
ENDS AND GROOVES PATTERN

Ends and grooves pattern: Adhesive is applied to the subfloor or to the underside of the board
located within 1" from both ends of the board and along the full length of the back, groove-side of
the board.
LENGTHWISE PARALLEL STRIPES PATTERN

Lengthwise parallel stripes pattern: Adhesive is applied to the subfloor or the underside of the
board located within 1" of each long side, edge, and middle of the board.
IMPORTANT! When using a trigger-activated flooring stapler with the glue-assisted
installation method, the installer must either stand on the floor, or apply a downward
pressure to the surface of each board as it is being nailed. This will ensure the flooring
does not lift away from the subfloor causing unnecessary vertical movement or hollow
noises.
Staple-Assisted Glue-Down Installation Method
• Glue-down is the primary installation method. The adhesive application should remain
the same as normal installation for the flooring being installed (see Glue Down Installa-
tion). The addition of mechanical fasteners is not intended as a replacement fastening
mechanism, rather a supplemental method.
• With full-spread installations over wood subfloors or screeds/sleepers, it is sometimes
necessary or helpful to blind-nail the flooring periodically to hold the flooring in place
while the adhesive sets up.
• This method may be appropriate where flooring needs to be driven tight during the
installation.
• There is no recommended nailing schedule for this method, as the fasteners are
strictly used as a supplement to the glue down method.
FLOATING INSTALLATION
All required pre-installation testing and preparation must be completed before proceed-
ing. Provenza recommends 6mil clear poly-film vapor barrier installation to prevent any
unforeseen moisture migration.
Acceptable subfloor types:
• CDX Plywood
• Concrete – With a minimum compressive strength of 3000 PSI.
