and underneath tile in aforementioned bathroom will be one of those
heating-blanket-mat elements to keep the floor nice and toasty on those
chilly florida mornings. yes, there are some...about two a year.
anyway, anybody else do this? I've read the on-line manual
(buyfloorheat.com) and I'm cool with laying tile, but I've never put the
mat under it.
apparently, you roll out the mat and trowel-out the mortar and lay tile
like usual. but don't scrape the wire with the trowel. well, every other
floor I did, I scraped the floor with the trowel notches, leaving only the
mortar that squeezed through the notches. this is with tiny v-notched
trowels on 4 x 4 up to 1/4" x 1/4" square-notched trowels for honkin'-big
16" x 16" floor tiles.
so...have I been doing it wrong? the tile always held, some's been there
for almost 10 years without a problem. should I not be scraping the
floor? I tend to think not, as, though the mat is thin, the wire is still
thick enough that the coat of mortar I usually leave won't be thick enough
to cover and get the tiles to adhere. on the other hand, laying a big
thick layer of mortar is a good way to get uneven tiles, as well as a floor
a half-inch higher than it used to be.
any thoughts/advice/experience available?
thanks.
