I love finding new products that make your life easier. Using Laticrete's epoxy grout was the only way to have a stain resistant grout and generally no need to re-seal, bad news was that it is gritty and clean up with vinegar made it impossible to use on marble or travertine and it's inflexibility ruled out using it with glass. That leaves ceramic, porcelains and some granite tiles. Now there appears to be a new product that is a lot more versatile.
Doing some research into GroutBoost and would like some feedback, especially with my Facebook friends who are in the stone business. I know everyone has a favorite brand of grout and this is an additive that you use instead of water and can be mixed with Laticrete, Custom, Mapei or Tec. Do you get the consistency that you want when it's mixed? Does it clean up with water well? Has anyone used it with slate or sandstone? My favorite sealer is Bulletproof by StoneTech but it's not on GroutBoost's approved list so I'm wondering why. I prefer to use products that I know won't change the look of the stone and that one is a personal favorite. Hopefully GroutBoost has been out long enough that someone is a real fan or did you try it once and decide it's not for you? Please let me know.
