My question is about which thinset to use. In my kitchen I'm installing a 1/8 " mesh mat of electric radiant heat flooring called "Thermasoft" over new cement board and underneath 18" porcelain tiles. My plan was to staple or tape the radiant mat to the cement board, then do a skim coat of mortar, let dry, install tile. The instructions suggest that I could just staple the mat and do the entire mortar job in one step. That seems iffy to me. It also suggests latex fortified or flex thinset. Anyway, is the ready mix thinset at Home Depot worth considering? If not, what is the best mortar to use for this project and where should I get it in the chicago area? thanks a lot
