aDhesive seLeCtion
Proper adhesive selection is determined by the type of
service the oor will receive. Using the proper adhesive
will help maintain tight joints and reduce the potential
for indentation from heavy loads.
AD-32 Adhesive is a pressure sensitive adhesive that
can be used over all approved porous and non-porous
substrates. AD-32 is recommended for residential and
light commercial applications where heavy rolling and static
loads are not expected. The adhesive is applied and then
allowed to dry to a tack before installing ooring.
AD-62 Commercial Adhesive is a wet-set adhesive that
dries hard and must be used in commercial applications,
where heavy static or rolling loads are present, where
temperature uctuations are likely to occur or when adjust-
ability during installation is desired. AD-62 is recommended
for use over porous substrates and select non-porous
substrates. DO NOT use AD-62 over existing resilient tile
or sheet ooring products.
Specialty Adhesives - Use Mapei G21 or G15 when
installing Structure in hospital rooms or medical facilities
where Hill-Rom beds are used or where frequent surface
wetting will occur such as in grocery store produce areas.
reCommenDeD substrates
For aD-62 aDhesive
• Porous Substrates (Concrete, wood underlayment
and patching and levelling compounds) - Before
installing ooring allow adhesive to dry/ash for 5 to 10
minutes. The ooring must be laid in to wet adhesive
to achieve 100% transfer of the adhesive to the back
of the ooring when rolled.
• Non-porous substrates (Cement terrazzo and some
steel trowel nished concrete) - It will be necessary
to allow the adhesive to dry/ash longer when cover-
ing over non-porous surfaces. Before installing ooring
allow adhesive to dry/ash 20 to 40 minutes or until the
valleys between the trowel ridges turn clear (the trowel
ridges will be wet) to achieve approximately 100%
transfer of the trowel pattern to the back of the ooring
when rolled.
* AD-62 Adhesive is recommended for large tiles because it
allows for adjustability during installation. AD-32 may be
used when job site conditions require the use of a pres-
sure sensitive adhesive.

• Always store and transport cartons on a at surface
neatly stacked no more than 15 cartons high. Ideal
storage temperatures range from 50ºF to 90ºF
(10ºC to 32ºC).
• Acclimate the room(s) ooring and adhesive at a constant
temperature between 65ºF and 85ºF (18ºC and 29ºC)
for 48 hours before, during and 72 hours after installation.
There after the room temperature should not exceed
90ºF (32º C) or fall below 55ºF ( 13ºC).
• Make sure the pattern is correct and the lot numbers are
the same on each carton.
