Roberts 3300 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 adhering carpet, mineral fibrous
felt-backed sheet vinyl and unfinished
cork underlayment (rolls).
Carpet Backings – Polypropylene
(ActionBac
®
), woven, Axminster, Wilton,
hot melt, latex unitary, needle-punch,
urethane foam (Enhancer
®
), polyurethane
laminate (LifeSpan
®
), sponge-rubber, jute,
and latex-foam. For backings not listed
please contact our Technical Department
at [phone].
For interior installations only. Do not
use this adhesive for pure vinyl or
vinyl-backed products. Roberts 3300
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
installed as the final flooring surface.
Roberts 3300 is not recommended for
cork underlayment when used for wood
flooring installations. When installing
wood flooring use Roberts 1408 to adhere
cork underlayment to substrate.
Substrates: Concrete, APA rated plywood, vinyl composition
tile (free of wax), primed gypcrete (refer to ASTM F2419) and
terrazzo. Check with the flooring manufacturer for their underlayment
recommendations.
Vinyl composition tile must be well bonded and limited to one layer.
Carpet should not be adhered to vinyl composition tile in high or heavy
traffic areas. Do not install a non-porous backed carpet over vinyl
composition tile.
Surface Preparation: Subfloors must be structurally sound, dry,
smooth, flat, level and 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.
Ensure the appropriate flatness/smoothness to prevent accelerated
wear or “show through” (telegraphing).

SUPERIOR
3300
Multi-
Purpose
Application and Installation: Spread
adhesive uniformly. Allow up to
30 minutes of open time before
you place your flooring into the
adhesive. 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.
Within the 60 minute working time,
place flooring into the adhesive while
the adhesive is still fresh and transfers
readily to the flooring backing. The
amount of open time and time in which you have
time 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 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.

Limited Warranty: Buyer assumes all risk of use, handling and storage
of product not in strict accordance with the label, printed literature and
industry standards. This limited warranty excludes all other express
or implied warranties including the warranties of merchantability or
fitness for a particular use or purpose. Any implied warranties arising
by operation of law are limited to one year. Roberts will not be liable
for any incidental or consequential damages. Some states do not allow
these limitations or exclusions, therefore they may not apply. This
warranty gives you specific legal rights and you may also have other
rights which vary from state to state.
Available Sizes:
Surface Preparation
(continued):
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 710 Standard Practice for Preparing Concrete Floors.
Wood – 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. Refer to ASTM F1482
Standard Practice for Installation and Preparation of Panel Type
Underlayments to Receive Resilient Flooring.
Existing vinyl composition tile (VCT) must be limited to one layer and
well bonded. Installation over VCT is recommended for residential or
light commercial traffic only. Remove all wax, floor finishes, dirt and
contaminants that may interfere with the bond. Ensure manufacturer
of flooring recommends installation of their product over VCT
before proceeding.
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.

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.
Flooring manufacturer’s products differ in characteristics and textures. Always check with the specific flooring
manufacturer’s recommendations for their specific trowel requirements. Less porous substrates typically require
a smaller notched trowel and longer open time than porous substrates. Ensure 100% transfer of adhesive to the
substrate and the flooring backing. Refer to Roberts Double Bond Installation Guidelines for trowel notches.
