Ensure that the subfloor is smooth, dry and free from dust. Visually check that there are no
objects on the floor that might damage the heating mat.
The basic rule is that if the floor is ready for tile, it is ready for Warmup. Consider floor prep
with a qualified flooring installer. StickyMats can be installed on plywood, cement boards and
cement slabs.
Always let leveling compounds cure before installing your StickyMat system.
Over concrete slabs, consider the use of Warmup insulation boards for best results. Review
specific installation guidelines online or call Warmup at 1-888-927-6333.
Where necessary, an appropriate smoothing compound should be applied and allowed to cure.
If the cable is being fitted to a solid floor it is essential that the concrete slab has been allowed
to cure.
If using the Warmup insulation boards, use a suitable cement based adhesive or screws to fix
boards to the subfloor as per the instructions.
If installing in a wet room ensure a slope in the mortar bed is maintained in order to direct
water to the drain pipe.
You are now ready to lay the heating mat.
Anti-fracture Membrane
Warmup heating mats are to be installed UNDER anti-fracture membranes. Follow the
manufacturer’s guidelines and ensure the mats are covered with thin-set or self-leveling
compound before applying the membrane. Do not apply floor heating systems above the
membrane as air-pockets may develop in the thin set and cause the cable to overheat.
Anti-fracture membranes provide no insulation so it is perfectly fine to lay the product
underneath. Additionally, it will protect the heating system during any necessary tile repair.
