Thanks, I will definitely try the grout sealer, will post. On the
subject of cold, I was told by one and all, DONT install the electric
mesh underneath, it's way too expensive, and that the tiles will just
take on the house temperature. Well, not quite true, I think an
electric mesh would have been a good idea. But, is it too late even now
to do something about it? Maybe not. How about gouging out the grout,
that will leave a gap of about 1/4" between tiles. Lay out wiring in
the inter-tile space, then put grout back, maybe mixed with cement to
withstand the heat (it's low volatge anyway). But then the question is,
will a sparse wire mesh (tiles are 12" x 12") heat up the surface?
Maybe so, if we kick up the power a little... Any thoughts on this?
Thanks and regards!
P.S A carpet under the kitchen dinette and a couple of other mats
thrown around definitely help for now
