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

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!

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.

I just used this product with great results. I have never grouted anything before but I would imagine this can be more difficult than traditional grout. Seriously read the directions and have a step by step plan ready. I used it for an existing shower floor about 12 years old, 3 x 3 inch non slip type tiles, 1/8th inch spacing, about 15 Sq Ft. total, and it just looked bad, moldy hard to keep clean. Rather than rip the shower apart I used a hand grout saw/razor blades and removed old grout and caulk, cleaned it up and sealed the tile with miracle 511 impregnator sealer. Try to work on a cool day it will extend working time. Highly recommend Proplus Epoxy Prewipe sponge (green). Make sure your rubber grout float doesn't shed or rub off I found a good one at HD, that M-D building products green epoxy float had trouble written all over it. I took out 10% by weight of part C and the consistency was good. To do the vertical corner wall seam where the tiles meet, I stuck my hand in a bag and grabbed a bunch out of the bucket, turned the bag inside out and cut a hole in the corner like I was decorating a cake. If you order the Full Parts A&B then you need the 9lb Part C, If you order the mini Parts A&B you need the 2.25lb Part C. I used about half of the Full size for my project. Thanks to the other reviewers for the tips, I will try and write a follow up after a while.

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.

Excellent grout system which i used in my walk-in shower.This was so easy to apply on my polished porcelain tile. Using an epoxy grout specific float, application was super easy and clean, with no excess grout remaining after scraping at 90degrees. Only the epoxy film was left behind that was completely removed without any haze using cleaning solution packets in the part a and b of the system.This was my first time using epoxy grout and i thought it was very easy to handle. As per the advice of others, i split the work into manageable parts and used a digital balance to weight out a 1:1:6 by weight of a:b:c components, and only mixed what i needed for each section.Color stable, water proof, low (no?) maintenance, the perfect grout! Incredibly easy with polished porcelain tile.
