Acceptable Underlayments:

• Wood Underlayment

Wood underlayment panels require a double layer construction and must be underlayment grade as specied

and warranted by the manufacturer. Always fasten underlayment panels in accordance with the manufacturer’s

recommendations. Any failure of the underlayment or Mohawk ooring as a result of the underlayment is NOT

the responsibility of Mohawk. Any porous wood underlayment must be primed.

• Concrete

• VCT (well bonded, on and above grade)

• Ceramic (well bonded) with a skim coat

• Terrazzo (well bonded)

• Self-leveling and patching compounds (latex fortied Portland cement based only)

• Resilient oor (no more than 2 layers, well bonded, non-cushioned – residential applications only)

• Radiant heat oors (not exceeding 85°F (29°C) and approved by the manufacturer for the use of their product

with resilient vinyl ooring applications)

• Gypcrete can be utilized when necessary due to radiant heat and in high rise buildings. Gypcrete must be sealed

using IVC FLEX-PRIM Acrylic Latex Primer to stabilize the surface for adhesive bond. All issues with gypcrete

cracking, crumbling, powdering and resulting in the release of adhesive bond are NOT warranted by Mohawk.

• OSB (underlayment grade)

OSB underlayment panels must be underlayment grade as specied and warranted by the manufacturer.

Underlayment panels and joints must be fastened and reinforced according to manufacturer’s instructions.

Completely sand the oor with a oor sander, so that the oor is smooth and at. Note: The chips in OSB

overlap. Without sanding properly, OSB has high and low spots throughout the oor that could telegraph

through the vinyl.

- Surface must be primed using IVC FLEX-PRIM Acrylic Latex Primer.

• Particle board (underlayment grade)

Particle board underlayment panels must be underlayment grade as specied and warranted by the

manufacturer.

- Surface must be primed using IVC FLEX-PRIM Acrylic Latex Primer.

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. Sand high spots to eliminate the possibility

of telegraphing. Prime oor if needed with IVC FLEX -PRIM Acrylic Latex Primer to prevent over absorption of

adhesives, dust containment, and to ensure a better bond of the adhesive to the suboor.
