Installation Guide

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 determines relative 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 iGrip 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 be immediately 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.
