Installation Guide

Floor Preparation:
Floor must be clean, smooth, at and dry. Remove all foreign substances such as wax, grease, dirt,
construction markings and contaminants, and any substance or chemical that would interfere with a good
bond. Fill all holes and cracks with a latex fortied Portland cement based patching compound. Tra󰮐cMaster
only recommends the use of latex fortied Portland cement based products as a satisfactory patching or
leveling compound.
We recommends priming extremely porous oors with Acrylic Latex Floor Primer to prevent over absorption
of adhesives, dust containment, and to insure a better bond of the adhesive to the suboor/underlayment.
Moisture Testing: It is the responsibility of the ooring contractor and the installer to conrm all concrete
substrates, both old and new, for moisture transmission using the Calcium Chloride Moisture Test according
to ASTM F-1869. Moisture vapor transmission should not exceed the recommended levels of 8 lbs. or less per
1,000 sq. ft. in 24 hours. This test should be performed and documented prior to installation. A second testing
option determinesrelative humidity in concrete oor slabs using In-Situ Probes, which should be less than
90% RH per ASTM F-2170 before, during and after installation. These acceptable moisture readings are only
applicable when using Roberts 2310 adhesive for sheet vinyl.
PH LEVELS: PH must be between 5 and 9
Inspection of ooring material prior to installation is required. Any defects should beimmediately reported to
the retail store from which the ooring was purchased before installation. Tra󰮐cMaster will not be responsible
for labor costs to repair or replace material with defects that were apparent before or noticed at the end of an
installation. The job site and all ooring material and adhesive must be kept for 24 hours before, during and
after installation between 65˚ F and 85˚ F (18°C and 29°C).
PLEASE NOTE: If removal of existing resilient oor covering is required, follow all recommended Resilient Floor
Covering Institute (RFCI) work practices at www.rfci.com.

PLEASE NOTE: 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 ooring backing.
