Tenax Ager as grout sealer too?

Hello,

I have installed a soapStone (http://g603.net) floor in my bathroom using rand (http://maplered.com) om shaped pieces from the quarry.  I grouted the floor with portland (http://maplered.com) cement and (http://maplered.com) brick sand (http://maplered.com) , since the joints get pretty wide in places and (http://maplered.com) the Stone (http://g603.net) is 3/4" thick.

Tenax has been recommended to me (and (http://maplered.com) I've found some info here too) as a color enhancer for after we sand (http://maplered.com) and (http://maplered.com) buff the Stone (http://g603.net) .

My question is, will the Tenax color enhancer also serve as a grout sealer?  If not, have you any recommendations?

Thank you!
