Stain free. Indestructible. Color fast. Absolutely the best.

Works great. Be aware it's a bit confusing the bright white color square, isn't the bright white ... it's completely white. watch the you tube videos and follow the advise and it will work out great. Slow shipping

Matches my bathroom white perfect

I thought this would be a smoother material when set. It seems to do the job, but I wish it were smoother

Ordered this twice and both times the carton came already open and used with product spilled into the bag it was in.

Grout should probably be reviewed after about ten years of service. I bought this to replace the traditional grout that I used when I installed a large built-in sink in my bathroom counter top. The traditional grout cracked relatively soon after installation, due to the mechanical and thermal stresses. (Yes, I am an engineer) I replaced that with some sanded caulk, which looks terrible but which was the best I could find at the time. When I found this epoxy grout, I figured it should be a much better match for the stresses it will face. So, I'll update this when it fails. Installation is a two person process IMHO. The mixed grout is a gummy mixture that had me worried as I started to do the installation. It was so gummy that I feared that it would set up too quickly and leave me with a big pot of waste. But, it stayed gummy for quite a while allowing me to work it into all of the tile in a small bathroom. The 2nd person is needed to wipe it down with the carefully prepared solutions while you continue to do the installation. Once done, it appears to be "tough" and for 3 months has done very well. But, time will tell.

Followed the directions for this Part C with Part A and Part B, and it applied well. I found that once I started to work the grout into the tile, it would stiffen fairly quickly (10 minutes), yet the grout in the pail remained very workable for an hour. Similarly, followed the directions closely on cleanup and I was very pleased with results. No third rinse with vinegar was needed. Time will tell on durability, but so far so good.FYI - I was regrouting 1930's era 4"x4" white tiles with very narrow grout lines (1/16"). Old grout cleaned out well into the grout gap, Done in December near Boston, where it was dry and 68 degrees in the house

This is a great and easy epoxy grout to use! Easy to mix, just follow the directions. Easy to apply. Just make sure to follow up with the cleanup rinses and your tile will not have residue. Absolutely waterproof and stain resistant.
