instructions in the kit.
3. The RMA (“Calcium Chloride”) test should be conducted after the HVAC
has been turned on and the area being installed has been appropriately
acclimated. False readings are possible if the area is not brought to
normal operating temperatures for at least 5 days. If the readings are
above 3 pounds per 1,000 square feet, DO NOT INSTALL!
Concrete Sub-floor Condition: The concrete sub-floor should be dry, clean,
non-scaled and free of dust, and flat to within 1/8" in 10 linear feet. The
surface should also be finished to a texture similar to 100 grit sandpaper. If
the concrete is glazed or very smooth, it must be thoroughly sanded or shot
blasted (see B-2) to assure proper adhesion. Remove all dust by vacuuming.
3. An adhesion test of at least 24 hour duration should be performed.
This is the safest check for bonding success to determine if curing
compounds, other adhesive bond-breakers or too smooth a surface are
present.
1. Adhesion Test – First, determine sub-floor temperature using a
floor thermometer, noting the cure rate chart under Section IV B.2.,
then determine moisture content (see II A-3).
2. The installer should make an adhesive bonding test (at least one
per every thousand square feet). Cut Rubber tile tile into 9" x 9"
pieces and install them using the recommended adhesive. These
test patches should remain in place for a minimum of 24 hours to
determine if there is good bond to the sub-floor and also to observe
if there is sufficient transfer of adhesive both to the sub-floor and to
the back of the floor tile.
3. Removing the test patches from the sub-floor should be difficult
with most of the cured adhesive remaining bonded to the sub-floor.
If proper bond is not accomplished, do not proceed with the
installation. Contact your Burke Flooring distributor.
4. Important: With respect to the type of concrete or other
cementituous patching material used in the sub-floor,
responsibility for a warranty and performance of the sub-floor
belongs to the concrete or cementituous patching material
manufacturer and the installer.
4. Curing compounds, bond breakers or sealers will seriously inhibit the
adhesion of the tile to the sub-floor. They should be completely removed by
