Thoroseal mixed with Acryl60 is a very good concrete waterproofing product. I've used it in foundation work for years.
However, I've never been able to get a response from the company when I've emailed asking if the product was a suitable substrate for a ceramic tile installation using thinset mortar.
We've had a couple situations here on the forums where I thought it would have been a good product for the particular application, but can't determine if it's actually suitable.
Perhaps you'll have better luck. They're here.
My opinion; worth price charged.
