Max Installation Guidelines 2
3. If the surface of the wood subfloor is not smooth, a ¼” underlayment panel should be installed over
the subfloor. Any panels selected as an underlayment must meet the following criteria:
> Be dimensionally stable
> Have a smooth, fully sanded face so the graining or texturing will not show through
> Be resistant to both static and impact indentation
> Be free of any surface components that may cause staining such as plastic fillers, marking inks,
sealers, etc.
> Be of uniform density, porosity and thickness
> Have a written warranty for suitability and performance from the panel manufacturer or have a
history of proven performance
B. Concrete Subfloor
1. Concrete subfloor should meet requirements prescribed in ASTM F710 standard practice for
preparing concrete floors. Concrete subfloors must be dry, smooth, and free from dust, solvent, wax,
grease, oil, asphalt sealing compounds and other extraneous materials. The surface must be hard and
dense, and free from powder or flaking. Surface of the slab should be flat to within 3/16” in 10’.
2. The final responsibility for determining if the concrete is dry enough for installation of the flooring lies
with the floor covering installer. Due to environment and indoor quality Adura
®
Max should not be
installed where excessive moisture emissions may exist. In accordance with ASTM1869-04. Moisture
emission from subfloor should not exceed 8 lbs. per 1,000 sq. ft. per 24 hours as measured with the
calcium chloride test. If using ASTM 2170 In Situ Relative Humidity Test, relative humidity should not
to exceed 85%. Mannington will not assume responsibility for floor covering failure due to hydrostatic
pressure or moisture vapor emission. New concrete slabs should be thoroughly dry (at least six weeks)
and completely cured. Although Adura
®
Max planks are not susceptible to damage from moisture,
excessive subfloor moisture is an ideal breeding ground for mold, mildew and fungus. All of which
can contribute to an unhealthy indoor environment. The Limited Warranties do not cover discoloration
from mold or flooding, leaking plumbing or appliances, water entering through sliding glass doors
or similar conditions.
3. Holes, grooves, control joints/saw kerfs and other depressions must be filled with a high quality
patching & leveling compound, troweled smooth and feathered even with the surrounding surface.
4. Concrete floors with a hydronic radiant heating system are satisfactory, provided the temperature of
the floor does not exceed 85°F at any point. Before installing the flooring, the heating system should
be turned on to eliminate residual moisture. Mannington does not recommend heated floor mats for

Max recommended work practices for removal of resilient floor coverings.
WARNING: Do not sand, dry scrape, beadblast or mechanically chip or pulverize existing resilient
flooring, backing, lining felt, asphaltic “cutback” adhesive or other adhesive. These products may contain
asbestos fibers and/or crystalline silica. Avoid creating dust. Inhalation of such dust is a cancer and
respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk
of serious bodily harm. Unless positively certain that the product is a non-asbestos-containing material,
you must presume it contains asbestos. Regulations may require that the material be tested to determine
asbestos content. RFCI’s Recommended Work Practices for Removal of Resilient Floor Coverings are a
defined set of instructions addressed to the task of removing all resilient floor covering structures.
These instructions should be consulted with each installation. The link can be found on our website.
