Lay Floor Covering
• Carefully lay the tiles and press
into the thinset.
• Grout the floor as soon as
possible as per the ceramic
thinset manufacturer’s
instructions. DO NOT switch
on the heater until the thinset
and grout has fully cured.
DO NOT use the heater to
accelerate the drying process
of the thinset or levelling
compound.
• Cover the installation with

Underfloor heating performs the most eiciently with conductive,
low resistance floor finishes such as stone and tiles. The maximum
thermal resistance of the floor must not exceed a thermal insulation
“R” value of 1·°F·h/Btu.
