3.0 Measuring the Mat and Installation
Preparation
Test the mat before commencing installation to
ensure there are no faults. Allow a distance from
the wall of 100mm when rolling out the matting.
This does not apply to conservatories where extra
heating is required.
The loose cables must be looped at least 40mm
from each other. They should not touch or cross
each other. Retest the mat when it has been laid
(section 4.0).
If the mat is too long it can be folded 180
o
(fig 5),
for example, by cutting through the fibre netting
without damaging the heating cable (fig 6). This
can be repeated a number of times (fig 7). If the
mat is still too long the cable can be cut loose
from the fibre netting and installed in loose strips,
please see section 3.3.
Using the System for the First Time
Allow the floor sufficient drying time before you
turn on the floor heating. The floor’s drying time
depends on many factors like room temperature,
ventilation and moisture. Generally the drying
time for floor cement is 3 to 4 weeks. Please verify
this with the floor cement/screed manufacturer.
Tile Cement
Unroll the MYSON mat with the heating cable
facing down so that only the glass fibre netting is
visible (fig 8).
Screed
Unroll the MYSON mat with the heating cable
facing up. This prevents the glass fibre netting
‘floating’ on the levelling screed. If necessary, the
mat can also be attached using double sided
adhesive tape.
