Installation Instructions
PRE-INSTALLATION SUBFLOOR REQUIREMENTS
All Subfloor must be:
Dry and will remain dry: Subfloor must remain dry year-round. Moisture content of wood sub
floors must not exceed 11%. Concrete must be tested for moisture content using the Anhydrous
Calcium Chloride test method, a non-invasive moisture meter, or a pin/probe moisture meter.
Structurally sound.
Clean: Thoroughly swept and free of all debris.
Level: Flat to 3/16" per 10' radius.
Wood subfloors must be dry and well secured. Nail or screw every 6" along joists to avoid
squeaking. If not level, sand down high spots and fill low spots with a Portland Based leveling patch.
Concrete subfloors must be fully cured, at least 60 days old, and shouId have minimum 6-mil
polyfilm between concrete and ground. Subfloor should be flat and level within 3/16" per 10'
radius. If necessary, grind high spots down and level low spots with a Portland leveling compound.
All concrete should be tested for moisture prior to installation using the Anhydrous Calcium
Chloride test method, a non-invasive moisture meter, or a pin/probe meter. When using a Calcium
Chloride Test, the result must not exceed 3 lbs per 1000 sqft in a 24 hour-period.
A moisture test must be performed to ensure that the concrete slab is dry. Remember, a concrete
slab on/below grade that measures dry today may become moist in the future due to rising ground
water. Installing a moisture barrier now may be viewed as an insurance policy against concrete
becoming wet in the future. Manufacturer is not responsible for site related moisture issues.
A minimum of a 6-mil polyfilm moisture barrier system is required between concrete and Rigid Core
Vinyl Flooring.
RADIANT HEAT
Rigid Core Vinyl Flooring is compatible with a concrete subfloor with an in-floor (embedded) radiant
heating system. The heating system must be 1 1/2" below the surface layer of the concrete slab.
Prior to flooring installation, the heating system must be operated at normal living temperatures for
14 days. Additionally, for 24 hours before, during, and after installation, the heating unit must be
turned off. Radiant heat systems must have failsafe capabilities to ensure surface temperatures do
not exceed 80°F (~27 °C).
Use of electric heating mats and other heating units directly underneath rigid core vinyl flooring can
void warranty.
