For Pergo Outlast+ Only
Revised: 3-Jan-2018
a. Pergo Outlast+ installation essentials must be met.
b. The crawl spaces must be enclosed and vented and meet all
requirements and the job site conditions must be correct.
c. Insulation of the floor in the crawl space is recommended.
d. The floor must not be installed in an area where it will be
exposed to constant dampness or extremely high or low
humidity. Relative humidity must range between 35-65%. The
temperature should be at least 60°F for the product
acclimation and at least 60°F two days after the installation.
17. C OMMERCIAL A PP L I C A T I ON S - (Only for those
products that are designated for commercial use by Pergo)
In commercial applications, an expansion space of
3
⁄8" is required
at all walls, pillars, pipes and other fixed objects.
Areas greater than 40 feet in length or width, and
consecutive multiples of 40 feet, i.e. (one room; two or more
rooms with adjoining archways greater than 4 feet; large
room with extended hallway) must have a T-Molding installed
across the width of the room, archway or at the beginning of
the hallway to provide additional expansion space.
When fastening fixtures to a floating floor, the anchoring bolts or
fasteners must have the same expansion space (
3
⁄8 inch) around
each bolt or fastener as required for walls, pillars, pipes and other
fixed objects.
Commercial flooring transitions that accommodate a
3
⁄8"
expansion space are strongly recommended.
18. INSTALLING PERGO OUTLAST+ FLOORING ON
STEP DOWN AND STAIR TREAD
APPLICATIONS - Stair nosing is used to finish stair
edges or step down applications. Prior to beginning the
installation, any loose or damaged treads or risers should
be repaired or replaced. The stairs must be cleaned
thoroughly from any loose paint, debris or old
adhesives.
Due to the many varieties of stairs available in North
America, a professional stair contractor may be required for
certain installations. Check local building codes before
altering dimensions of stair tread, riser and nosing.
Should there be any questions regarding the application of
Pergo on stairs, please call our Customer Help line at 1-800
33-PERGO (1-800-337-3746).
STAIR NOSING
■ Step down from a floating floor:
Cut the stair nosing to the desired length. The nosing must
be fastened with screws (i.e. finishing screw #6 by at least
1
1
⁄8"). A quality construction adhesive should also be used.
A 3/8" expansion space must be maintained between the
nosing and the floating floor. For step sown (from a floating
floor) to a lower level or at the top of a flight of stairs:
Adhere the stair nosing with a quality construction adhesive
and with #6 finishing screws 1
1
⁄8" in length. Place screws 2
additional screws at intervals no greater than 8 inches along
the length of the nosing
a. Use shims beneath the stair nosing as needed to match
the thickness of Pergo Outlast+ planks. Adhere the shim
to the nosing with construction adhesive and adhere the
shim and nosing to the subfloor with construction
adhesive and fasten with screws.
Stair Treads only: Adhere the stair nosing with a quality
construction adhesive and fasten with #6 finishing screw
11/8" in length. Place screws 2 inches from each end of the
nosing and space additional screws at intervals no greater
than 8 inches along the length of the nosing.
Use shims beneath the stair nosing as needed to match the
thickness of Pergo Outlast+ planks. Adhere the shim to the
nosing with construction adhesive and adhere the shim and
nosing to the subfloor with construction adhesive and fasten
with screws.
This illustration shows the
step down from a floating
floor. The step down
shows the tread flush or
even with the riser.
■ Tread flush or even with the riser.
The riser must be installed before the stair nosing is fit
into place. If installing from a floating floor, follow the
above instructions. When installing on a stair tread, the
nosing will be installed after the tread and riser are glued
into place.
■ Tread with an extended
round edge nosing.
The rounded portion of
the extended nosing will
need to be squared.
Leave as much of the
extending nose of the tread as possible, removing only the
radius (the rounded portion). On the edge of the squared
nosing, glue a narrow strip of Pergo Outlast+. Remove the
attached underlayment before gluing. This will finish the
exposed edge of the tread. After installing the tread and
riser the nosing will be installed, finishing the nose of the
tread. The illustration shows a step with an extended round
edge nosing. On the illustration a dotted line will show
where to cut the rounded portion of the extended nosing.
