Hi Baird, hope all is well in the "City of Brotherly Love". What type of
grout are we talking about sanded or unsanded? If they like color when it
was wet and the grout is porous try Aqua Mix Enrich N Seal (color enhancer).
Once Aqua Mix Enrich N Seal its down its not coming up, so test an area
first.

I had a shower/steam-room that the customer was complaining about stained
and dirty grout. The shower/steam-room was a 5 years old installation with a
stone floor and ceramic tile walls. The installer used Aqua Mix Enrich N
Seal on the stone floor and splashed the enhancer on the wall grout in the
lower portion of the shower/steam-room. The wall grout was a Polyblend
Mushroom that looked wet. I tried everything I could find to remove the
enhancer, with no success. I ended up re-grouting the shower.

I took a photo of a test I did for the customer this morning, please see
attached photo.

Keep in mind that if the grout IS NOT clean a color enhancer will enhance
the stains as well as the grout color. Also if the enhancer is absorbed by
the by the tile you could end up with a window frame. There are products
made to mix with penetrating grout sealer

e_start=20 I've never used any of the additives. I would be very careful
with concrete stains .... If you mix the stain with penetrating grout sealer
how will the pigment react with the solids in the sealer? Will the grout
evenly absorb the stain or will you end up with a splotchy mottled grout
color? Just some food for thought ....Good Luck.

Subject: [sccpartners] Darker Grout Lines?

Hi Everyone,
I have a client who recently had about 3000 sf of tile installed in his
house. Apparently they think that the grout is not dark enough for their
tastes (hydroment flash walnut) .  I inspected the floor and removed any
white efflourescent residue.  I then color enhanced a small strip of grout
with some impregnating sealer that they had around (I did not have a a
proper color enhancer on hand) and unfortunately it dried without darkening
the grout (although looked great when wet).  My plan was to go back and try
a solvent based color enhancer ( I have an old can of MB-? color enhancer).
But, was wondering if anyone has a good line on a decent color enhancing
product?  Would some dark concrete dye help if mixed with the enhancer?  It
would be great to find something that doesn't dry out too quickly or creates
a more or less permanent color enhancement/darkening.  Have thought about
color sealing with grout perfect color seal, but am concerned about the
color seal migrating beyon
 d the
grout line and wear and chipping down the line. It would seem to me that
color enhancer would be easier to apply and to touch up later.
Thanks so much.
