My buddy installed a new tile floor in his bathroom - Mannington
Perugia porcelian tile.
It's a very hard surface porcelain tile. Home Depot book on laying
tile states porcelain
tiles needs to be coated with a penetrating sealer before applying
grout. He called the
mfgr, Manninton, but did not get a direct answer.

Why not? They would be the authority on installing their product. Sounds
odd...

The Mannington
website did not have
any information on applying grout. Should he apply sealer to the
tiles before applying grout?
Should I post this message to another newsgroup?

Thanks,

Mike
