fiberglass reinforced sheet vinyl and luxury vinyl tiles. This product
dries quickly and offers a higher shear strength making it the adhesive
of choice for commercial installations where performance is key.
Features:
• Releasable or permanent bond
• High shear strength
• Plasticizer migration resistant
Enviro Friendly:
• Solvent Free • Low VOCs
Roberts R6300 is a solvent free adhesive and meets the strict
requirements of the South Coast Air Quality Management District and
may contribute one LEED point for “Low-Emitting Material–Adhesive
and Sealant” (IEQ Credit 4.1) and “Low-Emitting Materials–Flooring
Systems” (IEQ Credit 4.3). This product may also contribute one to
two LEED points for MR Credit 5 if product is manufactured within 500
miles of the project site. Visit usgbc.org for additional details.
Roberts R6300 is protected by GoldGuard
®
, an antimicrobial protection
system that inhibits the growth of mold, mildew and odor causing
bacteria in both wet and dry adhesive.
Uses: For the interior installation of vinyl back carpet tile,
commercial carpet cushion, fiberglass reinforced sheet
vinyl and luxury vinyl tiles.
Substrates: Concrete, APA rated plywood, vinyl
composition tile (free of wax), primed gypcrete (refer to
ASTM F2419) and terrazzo. Vinyl composition tile must be
well bonded and limited to one layer. Do not install over
vinyl composition tile in high or heavy traffic areas.
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 to ensure a
smooth, finished appearance to prevent show through and
accelerated wear. Patching compounds must be suitable
for the use application, polymer-modified and applied
according to the manufacturer’s instructions.
Expansion or other moving joints must not be filled or covered
with flooring. Refer to ASTM F710 Standard Practice for Preparing
Concrete Floors.
Wood – Subflooring, such as APA underlayment rated plywood,
hardwood, or other materials, must be flooring grade and installed
to the manufacturer’s specifications with adequate ventilation and
moisture protection. Expansion or other moving joints must not be
filled or covered with flooring.
Ensure wood substrates have a minimum 18 in. crawlspace with
adequate ventilation and moisture barrier protection. Cracks, chips
and joints must be properly patched or repaired. Refer to ASTM F1482
Standard Practice for Installation and Preparation of Panel Type
Underlayments to Receive Resilient Flooring.
Refer to CRI Carpet Installation Standard available at
www.carpet-rug.org.
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
Roberts R8100 Adhesive Cleaner
or 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 installation questions that are
not covered in this document please contact our Technical Services
Department at [phone].

WARNING: EXISTING FLOORING AND ADHESIVES MAY CONTAIN ASBESTOS. Unless you have confirmation that the
existing flooring system is not asbestos containing, do not sand, dry sweep, dry scrape, abrade, drill, saw, bead blast,
mechanically chip or pulverize existing flooring or adhesive without taking all appropriate precautions. Refer to local, state
and federal guidelines for treatment and removal of these products. You may also refer to the Resilient Floor Covering
Institute’s “Recommended Work Practices for Removal of Resilient Floor Coverings.”
EXISTING PAINT MAY CONTAIN LEAD. Unless you have confirmation that the existing paint is not lead containing, do not
sand, dry sweep, dry scrape, abrade, drill, saw, bead blast, mechanically chip or pulverize existing paint without taking all
appropriate precautions. Refer to local, state and federal guidelines for treatment and removal of lead containing paint. You
may also refer to www.epa.gov/lead.
General: 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 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 adequate ventilation during flooring installation.
Physical Characteristics (70°F, RH 50%):
Open Time: Up to 20 minutes
Working Time: Up to 40 minutes
Shelf Life: One year in unopened container
Product Type: Acrylic latex
Releasable Installation
Tack Time: 45 minutes
Moisture Vapor Emissions: 5 lbs. or less (ASTM F1869) /
80% or less (ASTM F2170)
pH must not exceed 9.0
Storage: Protect from freezing
Application and Installation: Spread adhesive uniformly using a trowel
or roller. Adhesive ridges should be of sufficient height to achieve full
coverage of the substrate and the deepest recesses in the back of the
flooring material.
When installing over a porous substrate, place flooring into semi-wet
adhesive for a permanent bond or allow adhesive to dry and become
tacky to the touch for a releasable bond. When installing over a
non-porous substrate allow adhesive to dry and become tacky before
placing the flooring. 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.
Lift a corner periodically to ensure 100% coverage of adhesive to the
flooring backing and the substrate. If the adhesive is not transferring
to the backing of the flooring; remove adhesive and reapply.
