There are several other user friendly grouts available that are every bit as good as epoxy grout.
Besides, I'm not so sure you will ever get it to stay on the ceiling and once you mix it you are committed to work it. With out previous experience, EPOXY GROUT IS A BITTCH!!
what he said^
also wondering why 3/8" grout space on polished wall tile?
wall tile usually has smaller grout joint than floor.
polished tile usually has joint up to 1/8" while less than 1/16" is ideal.
if it is limestone, travertine or marble sanded grout will deffinately scratch it.
if it is really 3/8" you will have a very hard time trying to get un-sanded grout to stay in and finish well.
do you have any other pics that show grout joint better?
