Garbage! Do not buy!
Bought this per manufacturer’s recommendation to go over Schluter DITRA-HEAT. This meets ANSI A118.1. Next day the tile came off when lightly picked by a finger. I’ve been in construction for over 15 years and know a thing or two about laying tile.

    Tried and true
    Keep in mind, this is just plain old cement. it's evident by it only costing 5 bucks. If your sticking membrane to a wall, you need to use schluters own product, as this will turn sandy like cement. I used it in combination with schluters own product and it worked fine, but I recommend mapei mortar since it's made specifically for installation of tile and membranes on walls. At 5 bucks a bag, you get what you pay for

      This $6 bag is easier to work than the $12 bag. However I recommend a bonding agent. as sometimes does not stick as well ti very flat slick surface like smooth concrete
