Ok so I am still a novice when it comes to tile work. I’ve messed around with bagged grout mix before when doing my old bathroom and had no luck with it not flaking apart over time. I decided to go with an epoxy grout this time around thinking this is going to hold up against the foot traffic in and out of my front doorway. To my surprise, it’s been almost 4 days and the grout mixture has not set up yet. It’s actually just as pliable as it was during application. If any of you guys can give me some insight on what I may have done wrong or how to correct this, that would be fantastic. Thanks in advance! *edit: please don’t treat this site like it’s Facebook. I’m just a fellow contractor looking for some insight to hone my skills and better my career.
