It's a Floor!

Yes! It’s a floor, in a living room. Perhaps not the most exciting pictures to look at, but did I mention it’s 320 square feet of slate and it’s heated.

I stripped out the old carpeting, removed the old baseboard heaters, and then pulled the padding and all of the staples.

Next step, lay out the 240V heat cable, wire it up. I used the type that comes on a spool, not the stuff pre-installed in a mat.
I zigged and zagged several hundred feet of cable 3” apart, taped it down to the floor with heat tape and then bedded it into self leveling mortar to a thickness of 1/4”. With natural slate the tiles are different thicknesses, so sorting by thickness and blending colors from different packs was in order. The rest of the job was just laying tile, mix thinset, lay tile, wait, grout, wipe floor (over and over).

Radiant heat floors are so nice, especially here in the cold, rainy northwest.
