Installation Guide
PERGO ON STAIR TREADS AND RISERS
1. Dry fit the Pergo planks net, or snug, stringer to stringer
(from left to right side). Remember that the depth of
Pergo tread material will be cut to accommodate
the width of the Pergo nosing which overlaps either a
riser of Pergo or the piece of Pergo which is glued on
the edge of the step.
a. One plank of Pergo will finish most risers; however,
two planks of Pergo will be needed for the tread
since tread depth exceeds the width of one
Pergo plank.
b. Personal preference will determine your choice
to install the riser or the tread first. In either event,
the joint between the tread and riser should be
sealed with Pergo sealant. Pergo quarter round
can also be used.
2. After dry fitting, the Pergo planks must be adhered to
the stair treads in one of the following ways:
a. Fully spread a premium quality parquet adhesive
on the tread and riser. This should be performed
in accordance with the manufacturer’s specifi-
cations. Make sure to press the Pergo into the
adhesive to get proper bonding. Allow the
recommended amount of time for the adhesive
to fully set up before using the stairs.
OR
b. Apply several continuous beads of a premium
quality construction adhesive across the full width
of the tread and riser. This should be performed in
accordance with the adhesive manufacturer’s
specifications. Firmly press the Pergo into the
adhesive to ensure proper bonding. Allow the
recommended amount of time for the adhesive
to fully set up before using the stairs.
NOTE: On wood or concrete surfaces, stair nosing must be
fastened with construction adhesive and screws to the
treads. A stair application is the ONLY time that a Pergo
floor is glued directly to a substrate. Pergo is installed as a
floating floor for a step down and all other applications.
■ Mechanical Fasteners for Stair Nosing Over Wood
Subfloors: Use a premium grade of construction
adhesive and trim screws at least 1
1
⁄8" in length. Drill
holes in the molding for the fasteners. Countersink
the screws and fill with Pergo Finishing Putty. When
fastening the stair nosing, space screws 2 inches
from each baseboard or stringer and a maximum
distance of 8 inches apart down the length of the
nosing.
■ Concrete Subfloors: Drill into the concrete subfloor
with a carbide drill bit. Insert an appropriate plug
into the concrete to accommodate the fastener
then follow the procedure above.
