Installation Guide

4.5 Using a razor knife, remove any wrinkles, or objects
trapped beneath the membrane, and then repair.
4.6 Chalk lines or other layout methods are easily
applied over the light-colored Mapeguard 2 surface.
5. Tile mortar or wood adhesive
Use an appropriate MAPEI latex polymer-modified mortar
meeting ANSI A118.4 and ANSI A118.11 industry standards
to set tile, or use a urethane adhesive to install wood. For
moisture-sensitive tile or stone, use MAPEI's Planicrete
®
W
urethane adhesive.
Note: For installation of tile larger than 18" x 18" (46 x 46 cm),
longer mortar-cure times may be required before tile can
be grouted or walked on. For shorter turnaround times when
installing larger tile, use a MAPEI rapid-set mortar such as
Ultracontact
™
RS or Granirapid
®
.
For additional information, instructions and
recommended protection, see the respective
MAPEI TDS for the mortar or adhesive selected.
6. Glue-down wood-flooring installation
(for sound reduction)
Apply a MAPEI urethane adhesive (Ultrabond ECO 975,
Ultrabond ECO 980 or Ultrabond ECO 985). Follow the wood-
flooring manufacturer’s instructions and recommended trowel
size. Note: Wood by nature will normally expand and contract
with variances in ambient relative humidity. Moreover, it is
MAPEI's experience that different species and/or different
wood construction of wood floors (e.g., engineered floors) will
undergo greater or lesser dimensional changes. Because of
this, some expansion and contraction of planks used for wood
flooring can be expected and therefore will not be considered a
defective condition resulting from using MAPEI's membrane.
7. Nail-down wood-flooring installation
(for sound reduction)
7.1 Follow Steps 2.2, 2.3 and 2.4 above.
7.2 Follow the wood-flooring manufacturer’s instructions.
EXPANSION JOINTS
1. Do not cover any substrate expansion joints with
Mapeguard 2, mortar or tiles. Provide for expansion
joints where specified. Refer to the most current TCNA
handbook for ceramic tile installation, Detail EJ171-07,
or TTMAC Tile Installation Manual, Detail 301MJ.
2. When necessary, cut tiles along both edges of the
expansion joints. Do not allow tiles and mortar to overlap
the joints.
3. Protect tilework with metal strips (edge metal) along both
edges of structural building expansion joints.
4. Install the specified compressible bead and sealant into
all expansion and control joints.
GROUTING
Select an appropriate MAPEI Portland-cement grout meeting
ANSI A118.6 or ANSI A118.7 industry standards, or an epoxy
grout meeting ANSI A118.3 industry standards. For additional
information, instructions and recommended protection, see the
respective TDS for the MAPEI grout selected.
CLEANUP
Remove excess MAPEI SM Primer or MAPEI SM Primer Fast
with mineral spirits.
PROTECTION
• Provide for dry, heated storage on site and deliver
materials at least 24 hours before tilework begins.
• Do not store Mapeguard 2, MAPEI SM Primer or MAPEI
SM Primer Fast in direct sunlight.
• Do not allow MAPEI SM Primer or MAPEI SM Primer Fast
to freeze.
• Protect Mapeguard 2 from spills, contamination and
damage before and during tilework to ensure a positive
bond with the mortar.
• Always provide proper protection of finished floors
when heavy equipment (such as fork lifts or scissor
lifts) is to be used over installations with sheet
membrane underlayments during construction.
