planks and tiles from natural movement; other uneven or unstable
substrates.
Substrate Preparation
Although PROCORE™ ooring is not susceptible to damage from
moisture, excessive suboor moisture is an ideal breeding ground
for mold, mildew and fungus-all of which can contribute to an
unhealthy indoor living environment. If excess moisture is found
in the substrate proper remediation steps should be taken prior to
installation.
All substrates must be properly prepared and tested according to
the following guidelines.
1. Concrete Subfloors
a. Concrete substrates should be properly prepared according
to the latest revision of ASTM F710, Preparing Concrete Floors to
Receive Resilient Flooring.
b. All concrete substrates, regardless of grade or age of slab,
must be properly tested using one of the methods outlined below
for warranty to apply. Acceptable test method is the ASTM F 2170
and ASTM F1869. Testing shall be conducted according to the
relevant ASTM documentation and instructions of the manufacturer
of the testing equipment. Consult Technical support for RH values
greater than 85% or MVER 5 lbs./1,000 sqft./24 hrs.
c. Concrete Alkalinity/pH Test shall be conducted in accordance
with ASTM standards. Acceptable level of pH in the substrate is
between 7 and 10.
2. Wood Subfloors
a. All wood substrates should be prepared according to the
latest revision of ASTM F1482 Installation and Preparation of Panel
Type Underlayments to Receive Resilient Flooring.
b. Wood panel suboor construction shall be a minimum of 1” in
total thickness.
c. Panels designed as suitable underlayment shall be at a
minimum ¼” in thickness, dimensionally stable, fully sanded face
to eliminate grain texture or show through, and have a written
manufacturer’s warranty and installation instructions. Panels shall
be installed according to manufacturer’s instructions regarding

• Above, on or below grade concrete without hydrostatic pressure,
excess moisture or alkalinity; must be fully cured and dry, free from
curing compounds, sealers, etc.
• Above or on grade lightweight concrete, properly prepared and
without hydrostatic pressure, excess moisture or alkalinity
• Above or on grade Gypsum concrete surfaces, properly prepared
and sealed, and without hydrostatic pressure, excess moisture or
alkalinity
• APA registered underlayment, sanded face exterior grade with

slab; luan and mahogany-type plywood panels; Masonite™ or other
hardboard or ber based underlayment; CCA (pressure treated), oil
treated or other coated plywood; CDX or other plywood with knots
or open defects; underlayment made of pine or other soft woods;
hardwood ooring; paint, wax, oil, grease, residual adhesive, mold,
mildew, and other foreign materials that might prevent oating
