Instructions / Assembly

5
at least 3/8" and less than 5/8"
from ends and edges. Ensure
PermaBase is tight to framing.
Joint Reinforcement: Trowel
bonding material to completely fill
the tapered recessed board joints
and gaps between each panel. On
non-tapered joints apply a 6" wide,
approx. 1/16" thick coat of bonding
material over entire joint. For all
joints, immediately embed 2" alkali
resistant fiberglass mesh tape fully
into applied bonding material and
allow to cure. Same bonding materi-
al should be applied to corners, con-
trol joints, trims and other acces-
sories. Feather bonding material
over fasteners to fully conceal.
FLOORS & COUNTERS
Subfloor or Base: For flooring
applications with 16" o.c. floor
joists, 5/8" tongue and groove
exterior grade plywood or 3/4"
tongue and groove exterior grade
OSB may be used. For 19.2" o.c.
and 24" o.c. floor joists, 3/4"
tongue and groove exterior grade
plywood or OSB must be used. Tile
size for floors with 24" o.c. floor
joists must be 12" x 12" or larger.
The joist and subfloor assembly must
meet L/360 as well as the appropriate
code tables for live and dead loads.
Underlayment: Using a 1/4"
square-notched trowel, apply a
setting bed of latex-Portland
cement mortar (or thin-set mortar)
to the subfloor or counter base.
Immediately laminate PermaBase to
subfloor or base leaving a 1/8"
space between boards at all joints
and corners. Leave a 1/4" gap
along walls.
Stagger all joints so that they
do not line up with underlying
substrate joints. Fasten PermaBase
every 8" o.c. throughout board
field and around all edges while
setting bed mortar is still workable.
Around perimeter of each board,
locate fasteners 2" from corners
and not less than 3/8" from the
edges. Fill all joints solid with
bonding material. On non-tapered
joints such as butt ends, apply a
6" wide, 1/16" thick coat over the
entire joint. For all joints, immedi-
ately embed 2" fiberglass mesh
tape fully into applied bonding
material; ensure that tape is
centered over joint. Apply bonding
material over fasteners to fully
conceal. Remove all excess bonding
material and allow to cure.
