I may be the only one that didn’t know this when Summer and I bought the marble for our master bathroom and kitchen, but you can’t just set (install) marble tile/slab with regular old grout. Certain colors of marble (Green and Black) will actually have a chemical reaction to regular old mortar and could cause discoloration and cracking. Also, marble is much heavier than tiles and some sort of adhesive should be used when stacking them up your wall (like in our bathroom). Because of all these reasons (and probably more that I don’t know about), it is recommended that you use Epoxy Mortar to install marble tiles.

Finding Epoxy Mortar to install marble tiles in Puerto Rico has been nearly impossible. I have called around and driven around to every store that sells marble for the past two weeks and either no one has any epoxy mortar in stock or they tell me that no one uses that in Puerto Rico, I’d be fine with normal mortar. Still looking.

I have even found it difficult to find suppliers of epoxy grout on the Internet. Hopefully, my phone calls to some suppliers around the mainland will be successful and we’ll be able to start our master bath and kitchen ASAP. If and when I find a supplier, I will post their name and number here for you…just in case you have a Puerto Rico construction project that involves marble.
