Subfloor Preparation
Fortane One™ can be used over the following subfloors:
concrete, Portland cement patch, terrazzo, ceramic tile,
radiant heat flooring, and cement backer board.
Mechanical surface profiling is the only accepted method
of subfloor preparation where warranties are issued. Acid
etching is not recommended. Shotblast the floor to
medium grit sandpaper texture to remove curing and
surface contaminants. Ensure that the subfloor is
structurally sound, smooth, dry, properly cured, clean and
free from dust, dirt, grease, oil, plaster, paint, old
adhesive, wax, curing agents, sealers, cutback or other
asphaltic-based residue and any other contaminants that
could interfere with a good adhesive bond.
For application of Fortane One™ over ceramic tiles, it is
necessary to grind the tile surfaces and clean thoroughly
with an industrial vacuum cleaner.
Before starting the installation, carefully check that the
subfloor is flat. Eliminate dips and crowns that exceed 1/8”
in a 10 feet radius by patching or sanding/ grinding. Do
not use product as a leveling agent. Where needed, use
only Portland cement based patching and leveling
compounds.
