To add to my last question�can this sealer be used to seal Mapei Ultracolor Plus Max high performance, rapid setting grout? The grout says it has bio block technology but I don't know what that means. I want to make sure it can be used over the grout I used. Thank you!!

If it is a standard sanded or unsanded grout and not a urethane or epoxy grout, then yes. The real test is whether the mortar is porous enough to accept the sealer. Test first with some droplets of water and if it penetrates, then this will work well.
