IVC US recommends the following guidelines for preparation and installation of all IVC US commercial

products. Please contact IVC US Technical Services at 888-225-8287 with any questions or visit

www.ivcgroup.us.

Section 1: Installation Preparation

Handling procedures: The job site and all flooring material and adhesive must be kept between 65°F

and 85°F for 48 hours before, during, and after installation.

PLEASE NOTE: If removal of existing resilient floor covering is required, follow all recommended

Resilient Covering Flooring Institute (RFCI) work practices at www.rfci.com.

Acceptable Substrates

Wood underlayment: Wood underlayment panels must be American Plywood Association (APA) rated

underlayment grade as specified and warranted by the manufacturer. All wood subfloors require a double

layer construction

Concrete: See Grade Levels

Gypsum concrete: Seal gypsum concrete with FLEX-PRIM Acrylic Latex Primer prior to applying floor

patch and adhesive to stabilize the surface for adhesive bond

Grade Levels

Suspended: An acceptable suspended floor is a concrete or wood substrate with a minimum of 18”

(460mm) of well-ventilated air space beneath it. IVC US recommends that a moisture vapor barrier be

placed on the ground below the air space.

On-Grade: An acceptable on-grade floor is a concrete substrate in direct surface contact with the ground

at the surrounding ground level. The concrete slab should be protected from moisture penetration and

incorporate a proven moisture vapor barrier.

Below-Grade: An acceptable below-grade floor is a concrete substrate partially or completely in contact

with the ground below the average surrounding ground level. The concrete slab should be protected from

moisture penetration and incorporate a proven moisture vapor barrier.

Acceptable surfaces

• VCT (well bonded on or above grade only – in the absence of waxes or sealers)

• Ceramic (well bonded & properly prepared)

• Terrazzo (well bonded & properly prepared)

• Self-leveling and patching compounds (Portland cement based only)

• Resilient floor (no more than 1 layer, well bonded, non-cushioned)

• Radiant heat floors (not exceeding 85°F)

Unacceptable Surfaces

iii

• Inter-flex and any perimeter bonded products

• Soft-back vinyl

• Cork

• Carpet

• Any floating floor system

• Resilient tile installed below grade

Commercial Installation Guideline Page 2 of 4 Concrete Testing Moisture Testing: It is the responsibility of the flooring contractor and the installer to confirm 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.

Commercial Installation Guideline Page 3 of 4 Section 2: Installation *Full-spread is the required installation method for all IVC US commercial products. Full-Spread Installation 1. Align the pattern with the most dominant wall, and using a sharp utility knife trim away excess material along the walls, cabinet and other permanent objects, leaving approximately 2” of material to be trimmed off later. 2. Make relief cuts at corners to allow the material to lay flat before the final cuts are made.

Commercial Installation Guideline i Page 4 of 4 Any failure of the underlayment or flooring due to the underlayment is NOT the responsibility of IVC US. IVC US does not recommend installing resilient flooring over wood flooring or wood subfloors applied directly over concrete or sleeper–construction subfloors. ii All conditions associated with gypsum concrete, including but not limited to cracking, crumbling, powdering and moisture, that result in bond failure are NOT warranted by IVC US.
