Paint the subfloor with Warmup
®
primer.
NOTE: It is not necessary to use the primer if you are
installing the heaters on an insulated tile backer board.
If the heater is being fitted to a wooden floor, the floor
should be boarded over with tile backer board or plywood
as specified in the technical notes section.
Before applying the primer ensure that the floor surface is
smooth, dry and free from dust or grease.
If necessary, an appropriate smoothing compound should
be applied and allowed to cure.
If the heater is being fitted to a solid floor it is essential
that the concrete has been allowed to dry before the
primer is applied. This can take 8 weeks or more.
If tiling on existing ceramic or quarry floor tiles, clean
the floor with an appropriate floor-cleaning compound.
Do not
then apply the green Warmup
®
primer, go to step 2.
Using the roller supplied, apply the primer evenly to the
entire surface to be heated.
The primer must be allowed to dry for a minimum of
3 hours. The light green colour of the primer will change to
a darker green once dry.
Good ventilation must be provided, which along with
a higher ambient air temperature, will accelerate the
drying process.
Avoid traffic over the subfloor once the primer has
been applied.
*If any sort of sealant has been used on the base
DO NOT
use the primer contained in the kit.
