Subject: Dolomite tile shower with epoxy grout

Partners,

Got called to this job about a month ago to resolve the staining issue in
this steam shower. I tried using a poultice with TSP and another section I
used 40 volume peroxide cream.
Both products worked but the peroxide cream was much quicker and easier to
use. Also the poultice left the area stained for more than a week while the
cream dried up within a day.
Over a few weeks we did about 3 to 4 Applications removing all the staining
and then we sealed everything with an impregnating sealer from M3.
I just got a text from the homeowner and the staining has reappeared. I know
that dolomite is a very sensitive material and probably should not be used
in a shower setting. Not sure if the epoxy grout is the problem.
Any thoughts from anybody?
Thank you,
Chris Santospago
