INSTALLATION GUIDELINES:
THE FOLLOWING SECTION OUTLINES THE PREPARATION
REQUIRED PRIOR TO INSTALLING THE HEATING FILM.
1. Ensure slab or wood sub-floor is structurally sound (follow TCNA
installation guidelines for sub-floor rigidity).
2. Concrete slab must be free of waxy or oily films and curing compounds
(when present, mechanical scarifying is necessary). If these chemicals
are present, water will bead. If the sealer is left on the floor, the mortar
for the tiles won't adhere. Remove sealer with a floor sander using
medium-grit sandpaper.
3. There should not be any protrusions sticking up from the sub-floor that
could impact or cause damage to the Heating Film such as nails, rebar,
or any other potentially damaging material.
4. Level the floor per TCNA guidelines. Allow the compound to dry
following manufacturer's recommendations.
5. Mop or sponge the floor with clean water to remove any traces of dust.
6. Make sure the floor is completely dry before installing EverWarm
Radiant Heat Film.
