LATICRETE SPECTRALOCK PRO Premium® Durable Stain Proof High Performance East to Use Non Sag Epoxy Tile Grout AB Full Unit/Requires 9 LB Part C Carton

As the pic shows, I had a large project. The kits are easy to mix and I'll assume all the colors will match as perfect as mine did. I had to do several different applications with several kits. It's not cheap but a shower is no place to pinch pennies (dollars!). First the bad. Once you mix you better be ready. You have about 20 minutes of smooth application before it gets real thick. It will wear you out pressing into 1/8 inch joints. Be quick and messy to get it down. Next, its work to wipe down and level out grout lines. The good: the hard work is worth the results. There is no worries about washing out the grout with too much water. It doesn't mix so you can use all the water you want. Next, the kits can easily be added after a previous application has dried. I can't even find "cold" joints in my job. It's been down about a year and still looks great. Helpful hint. When doing final rinse make certain no grout is stuck on walls, fixtures or on tile top. Once it drys, it will have to be grinded off. Don't be afraid to try the epoxy grout, it's worth the effort and money.

I bought a full unit, and split it into 8 separate parts (Part A, Part B, & Part C colored sand) as per users recommendations. Get a cheap food scale for $20. You can't split it equally by eye because Part B is like pudding and won't level. Reviewers were spot on; don't try to do any more than you can set in 30 minutes; a half mini or an eighth of a full unit. The mix is 1 (Part A):1 (Part B): 6 (Part C Sand). For a mini, it's 150 grams, 150 grams, 900 grams. For a full unit, it's 600 g, 600 g, 3600 g. I divided my full unit into 75 g, 75g, & 450 g. It took me 30 minutes to grout 1/8" lines on a countertop, and I started to clean up immediately upon finishing. Run a light sponge over the tile and grout lines, then spend the next 10 minutes cleaning up the wet grount lines with your finger making them perfect. Water won't pull the grout out. You can fill in any voids and smooth very easily while it's soft. The earlier you start the cleanup, the more easily everything is cleaned. Put a small amount in the freezer to use later for touchup. It slows the curing down so you can even use it the next day as soon as it warms. As soon as cleanup is done, I start the next batch. I did one batch per hour for 5 hours to finish, and I never felt pressed for time on either setting the grout or cleanup. If you do too much, you won't pay attention to detail or your cleanup won't go smooth. For large tiles I used a frosting bag to spread the grout before striking them in with a hard rubber float. This saves some cleanup, but isn't really too much faster.

Love this epoxy grout. I bought the 9 lb set. I divied it up into 4 parts and did it in four separate sessions. If I had not done this I would have been screwed. The grout sets up quickly and I needed to start cleaning as soon as I completed working in the first 1/4. I also used "Grout Release" product pre-applied to the tile. If I had not done both these things I would have a bunch of hardened grout all over the tiles without the possibility of cleaning it quickly enough (totally screwed, tear up the floor is the only solution). Use a scale to measure part C and divide the parts carefully. Also I just stirred it with a spoon, not a drill/mixer. (huge mistake, it hardens the grout prematurely). Good luck. End result worth it. Takes 7 days to fully cure, keep it clean for seven days. (hard with dogs on the kitchen floor.)

The description is very poor, and the instructions don’t say anything. This is 4 full units of part A and B. That equivilates to 16 mini units. You need 4 - 9lb part C bags to acompany this product. Excellent grout, just clean thoughroughly.

I've had a lot of issues with regular sanded grout over the years. Wash outs, cracks, degredation over time, staining.... I was nervious to order this because I had heard how hard it was to work with. Ignore that. I am pretty bad at most things in life and certainly no handy man.... and this went on just fine. I had plenty of working time before it firmed up. Clean up was a little more arduous than sanded grout, but it was fine. Just a few rounds of cleaning with a wet sponge. My only advice is to let it set up pretty good before you start cleaning. I was so nervious it would not be removable from the tile that I started scrubbing earlier than I should have and wound up pulling the smallest ammount out of the joints. End result is fantastic. A super solid barrier that I can tell is going to stand the test of time!

Like many DIYers easily swayed into bad ideas, I watched a lot of YouTube videos on tiling. I wanted my floor impervious to pet stains. So epoxy grout was the way to go. But there is so much nonsense out there about epoxy grout. And some may be legit for other brands. But I just followed the instructions and it turned out great. No dishwasher soap trick, no special cleanup chemical. Just the instructions in the box. After application, the floor looked like a real mess. After the first cleanup pass, it looked great. Not even sure I needed the second but did it anyway. So the one part of my first time tile attempt that I worried about the most was also the easiest. I did use it on porcelain tile. So that certainly helped too.
