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

placed on the ground below the air space.

On-Grade: An acceptable on-grade oor 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 oor 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.

• VCT (well bonded, on and above grade)

• Ceramic (well bonded)

• Terrazzo (well bonded)

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

• Resilient oor (no more than 1 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)

• 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.
