Check the cable resistance with a digital multi-meter every half hour or
so. If the cable goes open circuit (no reading on the multi-meter)
DO NOT
CONTINUE
- call the technical helpline on 888-WARMFEET (927-6333).
Tile and grout
The thin set mortar and grout must include an additive for
flexibility and be suitable for use with underfloor heating.
Refer to the manufacturer’s instructions for usage.
Check that the heating cable is fully taped and secure.
Tile as normal, taking care not to damage or dislodge the
heating cable with the trowel or with the tiles. If tiling
with mosaic or similar tiles, it is advisable to cover the
heating cable with latex self-leveling compound before
tiling to ensure a flat, smooth surface.
When selecting a trowel, we recommend 3/8” x 1/4” or
greater. When using a notched trowel, gently comb the
adhesive in straight lines in the same direction as the
runs of the heating cable. The trowel should be used at an
angle of approximately 45 degrees to the floor.
Do not
allow the trowel to make contact with the heating
cable while applying the mortar. Use sufficient mortar to
ensure that there are no voids or hollows under the tile.
If a tile has been positioned incorrectly, take great care
not to damage the heating cable when lifting.
Remember that tiles must not be lifted once the mortar
is dry, as this will damage the heating cable.
Do not
store
or cut tiles on top of the heating cable.
Do not
allow
chippings or dust to contaminate the floor during tiling.
Care must be taken not to damage the heating cable
during the tiling process. Use a piece of carpet, cardboard
or a dustsheet as a “crawl-board” to prevent the heating
cable from being damaged by your feet or knees during
the tiling process.
Grout the floor as soon as possible as per the ceramic tile
adhesive manufacturer’s instructions. The cable should
not be made fully operational until such time as the tile
or concrete installer verifies that the cement materials
are fully cured (1-3 weeks).
