Laticrete grout and also sealer-for-marble questions
We are redoing two bathrooms and I'm looking for some advice regarding grout and sealers.
The first bathroom floor will be honed carrera marble basket-weave with bardiglio dots. The second bathroom floor will be 2 inch carrera marble hexagons. The walls in both bathrooms will be 3X6 white subway tiles.
In terms of products, we're going with Laticrete. So based on everything I've read so far, is our understanding below correct?
-Use UNSANDED grout on the floors (because they are marble AND I expect the grout lines to be less than 1/8 inch).
-If this is correct, then Laticrete permacolor grout is the one to use and not spectralock.
Regarding sealing the marble tile on the floors (both the hex's and the basket-weave), should we:
-Seal BOTH before it is grouted AND after grouting as well?
-Use a solvent-based sealer (as opposed to a water-based one)?
Thanks in advance for your thoughts,
