Gyp-Crete®,
Gyp-Crete 2000,
Therma-Floor®,
Dura-Cap®,
Level-Right®,
Level-Right® FS-10,
and Level-Right
Plus Floor Underlayments
are smooth and
dense enough
to receive all
types of glue-down
finished floor
materials.
Before,
during and
after installation
of a Maxxon underlayment,
building interior
shall be enclosed
and maintained
at a temperature
above 50 ºF
(10 ºC)
until structure
and subfloor
temperatures
are stabilized.
Provide continuous
ventilation and
adequate heat
to remove moisture
rapidly from
the area until
the underlayment
is dry. Provide
mechanical ventilation
if necessary.
Under the above
conditions, a
3/4" (19
mm) thick underlayment
is usually dry
in 5 to 7 days.
Low temperatures
or high humidity
will lengthen
the drying time.
To ensure the
most effective
bonding possible,
the following
steps are recommended:
(1)
Check
for Dryness
Check
for dryness
using the recommended
procedure of
taping a 24" x
24" (609
mm x 609 mm)
section of plastic
to the surface
of the underlayment;
or lay a flat.
24" x 24" (609
mm x 600 mm),
high-density,
smooth rubber
mat weighted
down on the underlayment
surface. If no
condensation
or darkening
of the slab occurs
in 48 to 72 hours,
the underlayment
is considered
dry and ready
for the following
steps. Perform
additional tests
if necessary.
If
any gouges
or nicks occur
from construction
traffic. contact
your Maxxon™ dealer
for repair procedures.
(2-a)
Applying
Maxxon
Overspray
Porosity
of the floor
is a prime
factor in the
drying rate of
adhesives. This
porosity factor
may reduce the
effective adhesive
open time. An
application of
Maxxon™ Overspray
will minimize
the porosity
factor:
Before
priming,
test the
underlayment
for dryness.
The underlayment
must be fully
dry before priming.
Good ventilation
is necessary.
Open windows
approximately
3"- 4' (76
mm-1 01 mm) until
underlayment
is dry.
Dilution
Rate
Maxxon
Overspray--
4
parts
water

Overspray
After
diluting
per the above
rate, spray or
roll the Maxxon™ Overspray
at a rate of
300 sq. ft. (27.87
m 2) per gallon
of mix.
Make certain
surface to receive
the Overspray
is free of mud,
oil, grease and
other contaminants.
For maximum results,
the Overspray
is applied about
1-2 hours prior
to adhesive application.
Latex adhesives
will not achieve
maximum bond
until moisture
has dissipated.
(Note: Level-Right
FS-1O and Level-Right
Plus do not need
to be primed)
(or
2-b)
Maxxon
Acrylic
Sealer
or Maxxon
Overspray
(Optional)
Occasionally,
the underlayment
surface needs
to be left open
for long periods
of time during
demountable partition
construction
and office leasing.
The Maxxon™ Acrylic
Sealer or Maxxon™ Overspray
have been developed
to act as a temporary
wearing surface
during this time.
After Step 1
is completed,
dilute Acrylic
Sealer or Overspray
4: 1 by adding
4 gallons (15.1
L) of water to
1 gallon (3.8
L ) of Acrylic
Sealer or Overspray.
Spray or roll
this dilution
at a rate of
200 sq. ft. (18.58
m2) per gallon
of mix.
Important
1)
Maxxon™ Overspray
and Acrylic
Sealer are
non-flammable.
Do not freeze.
Do not ingest.
Overspray
or Acrylic
Sealer equipment
may be cleaned
with soap
and water.
2)
Where
floor goods
manufacturers
require special
adhesive
or installation
systems,
their requirements
supersede
these recommendations.
In this situation,
contact your
Maxxon™ applicator
to determine
the compatibility
of products.
3)
Finish

example)
that exceed

anti-fracture membranes
between the underlayment

membrane helps
eliminate tile
cracking caused
by structural movement
and acts as a waterproofing
membrane. See detail
A.
The Maxxon underlayment
must be dry before
the installation
of these membranes
unless otherwise
stated by the
membrane manufacturer.

Glue-Down Installations
Over Radiant
Floor Heating
Glue-Down
Laminated
Hardwood
Detail
B
Glue-down
laminated hardwood
systems tend to
be the most stable
flooring systems
for use with radiant
heat. The cross-plies
of the flooring
boards make the
flooring very stable
and resistant to
excessive expansion
and contraction.
Many wood flooring
manufacturers produce
pre-finished, square-edge
laminated hardwood
floors that are
indistinguishable
from nail-down
systems. Since
laminated systems
are generally thinner
than nail-down
systems, the radiant
system performance
is improved due
to lower resistance
from the floor
covering. See detail
B.

Follow
the manufacturer's
recommendations for
installations over
a cementitious underlayment.
"Floating
Floors" over
Radiant Floor Heating
Flooring
boards are glued edge
to edge and floated
on a 1/8" (3mm)
foam pad. Since
the flooring is laminated,
it is a very stable
system. Radiant
system performance
is about as good as
with glue-down laminate
systems. The
foam pad adds some
additional resistance,
but the floating floor
laminates are generally
thinner than glue-down
laminates, so the net
performance effect
is similar. See
detail C.

with
this system, 2" x
4" (50
mm x 101 mm) sleepers
are installed directly
on the subfloor and
tubing is installed
between the sleepers. The
spaces are then filled
with Therma-Floor® to
provide a thermal mass. Once
the Therma-Floor® has
dried, a vapor barrier
is laid down and the
flooring boards are
nailed directly into
the nailing sleepers
that were installed
on the subfloor. The
advantage of this system
is that the flooring
creates minimal insulation
above the heating system. The
disadvantage is that
the flooring can only
be nailed to a sleeper
which may not provide
enough fastening. See
detail D.

This
system is considered
a floating floor:
The radiant system
tubing and Therma-Floor
are installed conventionally.
Once the Therma-Floor
is dry, place a
vapor barrier and
lay 1 /2" (
1 3 mm) ACX
plywood on top
of the Therma-Floor,
alternating directions.
Spread a thin layer
of adhesive and
screw a top layer
of 1 /2" (
13 mm) ACX plywood
to the previous
layer. Leave 1/16" to
1/8" (1.5
mm to 3 mm) gaps
between all sheets
and put the ACX
side down on the
bottom layer and
up on the top layer:
The wood flooring
is then installed
in a conventional
fashion to the
plywood. Care must
be taken to prevent
nails from penetrating
into the Therma-Floor
and puncturing
a tube. See
Detail F.
When
laminated,
parquet or
solid wood
floors are
installed
over radiant
heating systems,
the maximum
floor temperatureshould
never exceed
85ºF
(29 ºC).
Recommendations
for Attaching
Carpet
and Pad
Mechanical Attachment
of Tackless Strips
Over Wood subfloors
If
the underlayment
is 3/4" (19
mm) thick, use "Acoustical
Concrete" tackless
strips like #20-451
manufactured
by Roberts Consolidated
Industries. If
the underlayment
is thicker than
3/4" (19
mm), use filler
nails every 12" to
18" (305
mm to 457 mm)
o.c. Use a filler
nail long enough
to penetrate
at least 1/4" (6
mm) into the
subfloor.
Mechanical
Attachment
of Tackless
Strips Over
Concrete
1) Use
standard tackless
strips with concrete
nails every 18" to
24" (457mm
to 609 mm). Use
a concrete nail
long enough to
penetrate through
the underlayment
a minimum of
1/4" (6
mm) into the
sub floor.
2) Use
an air compressor-driven
automatic nailer
to install diamond
point nails through
the tackless
strip and underlayment.
One type of nailer
is the Duo-Fast
Coil Gun (Models
1N-123, 1N-124,
1N-125) and 1
1/4" (32
mm) Duo-Fast
#054 nails.
When
Maxxon underlayments
have been
