Uses: For bonding pre-finished engineered and pre-finished
parquet (plain back).
Roberts 1407 adhesive is not recommended for
finished cork having a wear surface or a vinyl
backing. This adhesive is not recommended for
cork that will be inst
alled as the final flooring
surface. Roberts 1407 is not recommended for
cork underlayment when used for bamboo or
solid wood flooring installations. When installing
bamboo/solid wood flooring use Roberts R1509,
R1530, or 1408 moisture cure urethane adhesives
to adhere cork underlayment to substrate.
Roberts 1407 is not recommended for engineered
floors that utilize rubber wood or teak as a final
bonding (bottom) layer. This prod uct is not
recommended for engineered wood flooring
that is greater than 1/2 in. thick, more than 5 in.
wide, solid wood flooring or bamboo. Instead use
Roberts R1509, R1530, or 1408 adhesives.
Substrates: Concrete (on and above grade), APA
rated plywood, oriented strand board (lightly
sanded), acoustic cork underlayment, primed
gypsum underlayment, terrazzo and radiant heated flooring
systems.
Surface Preparation: Subfloors must be structurally sound, dry,
smooth, flat, level, free of excess moisture/alkali and all substances
(oil, wax, grease, paint, oil based sealers, etc.) that might interfere
with the performance of the flooring or its installation.
All substrate cracks, holes, high spots and irregularities must be
adequately repaired. Patching compounds must be cement-based,
polymer-modified, suitable for the use application and applied according
to the manufacturer’s instructions. Expansion or other moving joints
must not be filled or covered with flooring. Refer to ASTM 710 Standard
Practice for Preparing Concrete Floors.
Concrete must be flat (≤ 1/8 inch in 10 ft.) with a minimum 3,000 psi.
Burnished or steel troweled concrete must be roughened using a
minimum 30-grit abrasive. Irregular substrates will lead to “hollow spots”
or “popping.” It is very important to have a smooth level surface.
Wood Substrates – Subflooring, such as APA underlayment grade
plywood, hardwood, oriented strand board (lightly sanded), or other
materials, must be flooring grade and installed to the manufacturer’s
specifications with adequate ventilation and moisture protection.
Ensure wood substrates have a minimum 18 in. crawl space with
adequate ventilation and moisture barrier protection. Cracks, chips
and joints must be properly patched or repaired. Wood substrates

The trowel notches referenced are those typically recommended for the type of flooring being installed. They
are normally the minimum size recommended. Surface conditions (roughness and porosity of substrate), type
of flooring and backing will ultimately determine the required trowel notch size and coverage.
Always check with the specific flooring manufacturer’s recommendations for their specific trowel
requirements. Ensure 100% transfer of adhesive to the substrate and the flooring backing.

of sufficient height to achieve full
coverage of the substrate and the
deepest recesses in the back of
the flooring material.
Place flooring into the adhesive
while the adhesive is still fresh
and transfers readily to the flooring
backing. The amount of time in
which you have to place the flooring
will vary with temperature and
humidity. The higher the temperature
and the lower the humidity the faster
the adhesive will set.
Ensure boards are in full contact with
the adhesive. Lift a board periodically
to see if the adhesive is transferring 100% to
the back of the flooring. If the adhesive is not transferring to the backing
of the underlayment remove adhesive and reapply.
After Installation – Restrict foot traffic and moving of heavy objects for
24 to 48 hours to allow adhesive to cure properly. Premature traffic can
cause installation failure.
Clean Up: Fresh adhesive – warm soapy water. Dried adhesive – use
mineral spirits sparingly with a clean, white cotton cloth. DO NOT POUR
CLEANER DIRECTLY ONTO FLOORING.
Refer to material safety data sheet, www.robertsconsolidated.com and
industry standards prior to installation for additional information. For

Services Department at [phone].

Available Sizes:
Surface Preparation
(continued):
must not have more than 12% moisture content. Ensure moisture
content of wood subfloor is within acceptable moisture range of wood
flooring prior to installation.
Gypsum Substrates – Gypsum based underlayments must be
appropriately cured, dry, on or above grade, with a compressive
strength of >2,500 psi for solid wood and >2,000 psi for engineered
wood flooring. Consult flooring manufacturer for their specific
recommendations for gypsum based underlayments.
General: Ensure HVAC is fully operational and is set to the temperature
that will be maintained during the life of the flooring installation.
Ensure substrate, flooring material and adhesive are fully acclimated
prior to installation at the same temperature and humidity level
expected during normal use (between 65–95°F) with a relative humidity
(RH) of no greater than 65%. Refer to flooring manufacturer’s specific
recommendations and industry standards.
Materials, substrate and area temperature must be between 65–95°F
with a maximum RH of 65% for 48 hours before and during installation as
well as for 72 hours afterward. Large temperature or humidity increases
or decreases can affect the flooring and performance of the installation.
Ensure radiant heated floors have been in operation and that all excess
residual moisture is removed (evaporated) from the system and the
concrete slab is fully cured. Turn the heating system off to ensure that
the adhesive does not dry to fast.
Ensure that you are installing a dimensionally stable species of wood;
narrower boards are typically more dimensionally stable than wider
boards. Once the flooring is installed slowly raise the temperature to the
normal operating temperature at which the system will be maintained
(no higher than 80°F).
Ensure adequate ventilation during flooring installation.

manufacturer’s installation guidelines .
