Floor Coverings - Tiles & Stone
When installing the mat under tile or stone flooring choose one of the following methods:
1.Single Layer Method:
Apply a layer of 3/8” thinset cement or adhesive over the heating Cable.
Lay the tile or stone directly into that layer of thinset cement.
2.Double Layer Method:
Embed the heating mat in a skim coat of thinset or self-leveling compound completely covering
the heating element and the sensor wire. Using a rubber float, spread the thinset over the cable
in the same direction as the wire. Ensure that the space between the cable is filled. Allow this
layer to dry completely.
Apply a second layer of thinset or adhesive and lay the tiles as usual. The required minimum
total for both layers is 3/8” of thinset or adhesive.
When deciding between the single layer or the double layer method you should consider the
following:
We do NOT recommend the single layer method if you will install mosaics or a combination of
tiles of different sizes.
If this is the first time installing underfloor heating the double layer method is highly
recommended.
Waiting Period: Ceramic tiles and stone installations require 1 to 3 weeks for the thinset
to cure. Do not switch on the underfloor heating system until you have allowed the thinset
material to fully cure. Failure to do so will result in damage to the system and cause the thinset
to become brittle.
Carpet, Vinyl or Laminate Flooring
Embed the heating mat and cable in a layer of self-leveling compound and let it dry. Ensure
that the heating mat and cable are covered with a minimum of 3/8” of self-leveling compound.
Note : The under floor heating mats are NOT approved for direct contact with combustible
material. The heating mat MUST always be embedded in thinset / cement mortar / cement
based adhesive glue / tile adhesive before installing floating wood or laminate floors.
