4.6 Applying Self-Levelling Cement
Fig. 4.6
Measure the cable’s electrical and insulation resistance and record the
readings on line 3) Before embedding the heating cable in self-levelling
cement of the measures’ table.
– Consult the manufacturer’s instruction for the type of floor covering (ceramic,
linoleum, or other). See Section 7, ”Expert Tips”;
– Completely embed the heating cable in self-levelling cement (Fig. 4.6). It is
crucial that the ENTIRE heating cable (BLACK) be embedded. No part of the
heating cable (BLACK) must be exposed. (A small part [top] of the heating cable
may be exposed at the surface of the self-levelling cement ONLY IF a ceramic
glue is used afterward AND embeds that part);
– Level the subfloor with self-levelling cement or cover the cable with a layer of
cement glue when installing the stones or ceramics.
IMPORTANT!
Do not turn on the Therma Cable floor heating system before the cement
has completely dried. Follow the manufacturer recommendations, it take’s up
to 30 days for both products (48 hours for the self-leveling cement and 30
days for the binder cement).
Once the cement or binder has dried, measure the cable’s electrical resis-
tance and record the readings on line 4) After embedding the heating cable
in cement of the measures’ table.
