be maintained at a minimum of 65° F and a maximum of 75°
F
for 48 hours before the installation, during the installation and
for 48 hours after the installation is completed. The flooring
materials and adhesives shall be conditioned in the same
manner. Wood subfloors must have a minimum 18" (47 cm) of
cross ventilated space between the bottom of the joist and
ground. Exposed earth crawl spaces should be sealed with a
polyethylene moisture barrier. Subfloors should meet local and
national building codes. Trade associations, such as the
American Plywood Association (APA), offer structural
guidelines for meeting various code requirements. Single
Wood and Tongue and Groove subfloors should be covered
with 1/4" (6.4 mm) or 1/2" (13 mm) APA approved
underlayment plywood. Use 1/4" (6.4 mm) thick
underlayment
panels for boards with a face width of 3" (76 mm) or less. For
boards wider than 3" (76 mm) face width use 1/2" (13 mm)
underlayment panels. Countersink nail heads and fill
depressions, joints, cracks, gouges, and chipped edges with a
good quality Portland cement based patching compound. Do
not install over OSB (Oriented Strand Board), particle board,
chipboard, lauan, or composite type underlayment.
Concrete shall be prepared utilizing ASTM F 710, Practice for
Preparing Concrete Floors and Other Monolithic Floors to
Receive Resilient Flooring. Floors shall be smooth, flat,
permanently dry, clean, and free of all foreign material such as
dust, paint, grease, oils, solvents, curing and hardening
compounds, sealers, asphalt, and old adhesive residue. Floor
covering shall not be installed over expansion joints.
It is essential that moisture tests be taken on all concrete
floors regardless of age and grade level. One test should be
conducted for every 1,000 sq. ft. of flooring and the results not
exceed 5 lbs. per 1,000 sq. ft. in 24 hours when tested in
accordance with ASTM F 1869 Standard Test method for
Measuring Vapor Emission Rate of Concrete Subfloor using
Anhydrous Calcium Chloride or 80% when tested accordance
with ASTM F 2170 Standard Test Method for Determining
Relative Humidity in Concrete Floor Slabs using in situ
Probes. If the tests results exceed the limitations, the
installation must not proceed until the problem has been
corrected.
