   Thorocrete makes Wilbond or someone makes something like that.

   It's a bonding agent.

   There is so much sticky stuff in thinset you do NOT need this.

   What's next?

   Theee is a product called Red Guard, used for waterproofing.  I have used one from MerKrete ... it's a semi-thick black goop that you can roll or trowel onto a surface for waterproofing.  It sets up like a sheet of rubber.  Both of those are sold at my tile place.

   But if you're going over cement board or hardiebacker, you don't need it to make the tiles stick better.  Just wipe it off with a damp cloth to get the dust and dirt off.

   Thanks for the info. That saves me worry I'm forgetting a step.

   Can you tell me with Hardiboard do you have to use a screw in every hole marked on the board or can I use maybe just 10 or 12?

   I always trowel on a thinned layer of thinset, then set the hardie, then screw it about every 6-8 inches, so I guess that means most of the printed dots.  Screws are cheap, and once I get to screwing around it's hard to stop.   :)

   i use coil roofers on every dot. way faster than screwing, and i've never had a pop. those screws never seems to set flush. either fastener you use, yes, every dot. they keep the hardibacker in tight contact with the thinset until it sets up.
