I know it would be something 'off label' to use the product for what I am thinking.
I would like to warm a section of granite countertop and wondering if a 1x5.5 warming mat could work.
Was thinking of fixing it to the underside with thinset or similar , the directions talk about leaving a 2 inch space when using under floors. wondering if even without that space the product would still warm the area in question.

The UnderFloor mat you're talking about wouldn't need to go in mortar, and in fact the mortar wouldn't stick to the foil on either side of it anyway. It would just staple to some nailers that were 1' on center. Without that 2" air gap, though, it will have a hard time heating the countertop. The way these work is to actually heat that gap, which then heats the floor (or whatever you have). If there is no gap, there is no air to heat, and it will do much much worse. You'll also lose heat downwards, since I imagine you couldn't insulate under it. My guess is that the mat wouldn't do so great in that situation.

thanks, that makes some more sense. If mats can't be cut only way to get a specific size is custom order correct (expensive to an already semi silly project)
proof of concept with a heating pad worked well....duck tape kind of ugly however. (its going on the overhang of an island seating area, that gets very cold when cheap skates like me turn the heat down to 50 at night)

The UnderFloor, with the foil, can't be cut, correct. We don't do custom sizes of those either, or really of any mat. The regular TapeMats can be rearranged however you want, and the WarmWire is already just a loose wire, but the UnderFloor can't be changed.

For the record, I purchased 10sq. feet of warmwire and installed it under a granite bar top counter in our kitchen, works great. Not very practicle but makes for a comfortable cup of coffee in the morning. (havent gotten the electric bill yet)
