3. INSTALLATION
The installation of Burke Rubber Floor Tiles should not begin
until the work of all other trades has been completed,
especially overhead trades. The areas to receive flooring
materials shall be clean and fully enclosed. The area should 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.
