I sooo want to use colored grout in the art room this year for the kids mosaic lesson - I'm usually hooked on black...use it all the time and lament the fact that I lost all contrast with the tiles - so I tried tinting the grout with acrylic paint - AND IT WAS AWESOME!
used the paintbrush to 'sniggle' it (all technical artist terms) in the nooks and crannies
TIP : the paint thins the grout so the set up time is a bit longer
the grout needs to 'rest' for a bit longer - so 10 minutes or so
then you can do the first wipe off of the colored grout with a super dry sponge - always use a clean part of sponge or you'll just smudge the grout instead of removing it -and clean your sponge A LOT in-between! then let it 'rest' again - 15 minutes - then polish each tile....
