moisture, dust, sealers, primers, paint, oxidation, curing compounds, parting agents, residual
adhesives, adhesive removers, hardeners, resinous compounds, solvents, wax, oil, grease,
asphalt, gypsum compounds, alkaline salts, excessive carbonation or laitance, mold, mildew,
any other extraneous coatings, films, materials and all other foreign matter which might
interfere/restrict proper adhesive bonding. DO NOT use sweeping compounds, solvents, citrus
adhesive removers, or acid etching to clean the substrate. DO NOT install over gypsum-based
or plaster based leveling or patching compounds. DO NOT install new floor covering over old
floor covering, as the old floor covering may not be adequately bonded, hide possible structural
defects, or cause plasticizer migration into the new stair treads and flooring. In renovation or
remodel work, remove all existing* adhesive residue so that 100% of the overall area of the
original subfloor/substrate is exposed. Follow The Resilient Floor Covering Institute’s (RFCI)
“Recommended Work Practice for Removal of Existing Floor Covering and Adhesive, and all
applicable industry, local, state, and federal standards. Care must be taken to analyze the
conditions and correct any problems prior to installation. Follow the manufacturer’s
recommendations for any patching or underlayment materials, excluding gypsum based or
plaster based levelers or patching compounds.
*Some previous manufactured asphaltic “cutback” contained asbestos. For removal instructions,
refer to the Resilient Floor Covering Institute’s publication “Recommended Work Practices for
Removal of Resilient Floor Covering”.
6.2.2 Concrete substrates on all Grade Levels must be tested in accordance with ASTM F 1869
Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using
Anhydrous Calcium Chloride or ASTM F 2170 Standard Test Method for Determining Relative
Humidity in Concrete Floor Slabs using in situ Probes to quantitatively determine the amount of
moisture vapor emission at least one week prior to the installation. Caution: ASTM F 1869 or
ASTM F 2170 tests cannot predict long-term moisture conditions of concrete slabs. Moisture
testing only indicates moisture conditions at the time the tests are performed. Before conducting
ASTM F 1869 or ASTM F 2170 test, the installation area must be maintained between for 65° F
(19°C) and 85° F (30°C) for at least 48 hours prior to testing, during testing and thereafter. In
addition, the concrete’s temperature range must also be identical to that of the installation area.
Conduct three test for the first 1,000 sq. ft. and one additional test for each 1,000 sq. ft. or
fraction thereof per grade level. The Vapor Emission Rate shall not exceed 5.0 lbs and Relative
Humidity Test shall not exceed 75% when using Roppe 535U “Universal” Urethane Enhanced
Epoxy, ROP435 Epoxy Adhesive and ROPECC Epoxy Caulking Compound. ROP360 Vapor
Emission Rate shall not exceed 4.0lbs and Relative Humidity Test shall not exceed 70%. Quik-
Stik Adhesive Vapor Emission Rate shall not exceed 3.0lbs and Relative Humidity Test shall not
exceed 65%. If the substrate does not meet the above noted requirements, the flooring shall not
be installed until the problem has been corrected. DO NOT install flooring if there is hydrostatic
pressure. Every concrete floor slab on-grade or below grade to receive resilient flooring shall
have a permanent, effective moisture vapor retarder installed below the slab. A pH test must be
performed to test for excessive alkalinity using a pH pencil or litmus paper and deionized water.
A scaly, sandy, or powdery surface is an indication of some form of contaminant, usually
excessive alkalis or an alkali-silica residue. A pH reading higher than 8 is an indication of a
