Hello Maurizio, I have purchased tumbled marble for the backsplash. I want to install this myself. I have a couple of questions, I was sold the Flextile 200 for the adhesive is this sufficient for the backsplash? Also, should I grout before sealing? or seal then grout? Please advise... Ellen
Dear Ellen:
Flextile 200 is fine.
You install, grout and then - after at least a couple of weeks to allow for proper curing - you apply the impregnator.
Considering that you probably have large gout lines, one week of curing period should probably do.
