    Good day everyone,

    I've been lurking the forums for a bit now but this is the first time I've needed to ask a question!

    12x12 Cermaic tile on gypsum floor in a condo. Is there a suggested mortar and grout that one should use on gypsum?

    Also thanks to you all for compiling such a amazing source of information!

    There are requirements for gypsum minimum standards, is it cracking? I think it’s a gamble each job. Schonox seems to take the lead, may need primer to isolate, I know it causes reaction between the Portland. I believe Mapei May have come out with proper thinset recently.
