Tile Floor / Electrical Radiant Heat / Mortar Not Setting

aaldrich55443 · 01-07-2013, 12:55 PM

I installed a tile floor in a lower level bathroom. The tile is 6" * 24". I purchased the tile and the "premium mortar" from Menards. I laid the electric matting, mortared over the mat. For areas where I mortared over the mat - had good success with the tiles setting. For areas where there was no matting, and required a thicker mortar base, the mortar is not hardening. It's about 3/4" thick. I have placed a heater in the bathroom to try to warm the space.

My question is: will this mortar eventually set? or do i need to remove and redo with powder mortar that can set in cold spaces and not have as much water content?

Something tells me you did not use real mortar, but something pre-mixed. How about you tell us what mortar you used?

This is the link to the product that used ... Thanks for your help. By the way, I laid this on a concrete basement floor in Minnesota ( it's a little cold at this time of the year)

There's only one good thing about that product for what you used it for. The empty bucket.

You chose the wrong product-----You need a powdered modified thinset----

That product requires air to dry----no air under a tile----You may have installed the mat incorrectly also---What did the manufacturer ask for as a setting material----

Looks like a scraper night ...! Complete bummer. I chose this product to save me some time - looks like it's only costing me time now. As for the heat matting, I thought I followed the directions - laid flat on the floor, taped / glued where I was suppose to do so, and applied the "mortar" which obviously isn't mortar over the mat. I hope I didn't lose the mat in the process - the darn thing isn't cheap. I'll let you know how this shakes out.
