Hello again ..

Believe it or not - I have started laying tile in my bathroom. It is going pretty well. Recently the wife and I decided to change materials - again - and use a pebble mosaic on the floor.

I am going to assume they are natural stone - I was hoping for some info from the pros.

1) Do I need to seal the tiles before or after they are set?

2) I am going to assume Flexbond Polymer modified thinset is good for setting mosaic over mud?

3) I have a grout additive, that is expensive by the way, that I've seen used on job sites, and the salesman of course swears by. It is called Grout Boost and claims to protect grout from stains and you never have to seal .. blah blah blah. I also have Tec acrylic grout additive. Does anyone have a preference - the grout will most likely be bright white.

Any advice is appreciated.

Thanks again for all your help..one of these days I'll post some pictures...

Thanks..

Dougie
