for the installation of fiberglass reinforced sheet vinyl, vinyl backed
carpet tiles, commercial carpet cushion, and luxury vinyl tiles
(12 in. x 12 in.).
This product may be used as a releasable adhesive or a permanent
adhesive (if flooring is installed while adhesive is still wet a
permanent bond will be formed).
Features:
• Permanent or releasable
• Works with a variety of flooring types
*Enviro Friendly: • Solvent Free • Low VOCs
Roberts R6280 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 R6280 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, flooring grade APA rated
plywood and terrazzo.
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 Substrates – 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.
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.
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.
Clean Up: Fresh adhesive – use
Roberts R8100 adhesive cleaner or
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.

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.

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.
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.
