This is a great product. If you simply follow the directions, the product is very easy to install. I am not a professional a very experienced DIY'er and found this product easier to install than cement grout. The key is to follow the directions provided with the product. Here are some tips and tricks for a successful installation but beware, it's very long. Don't be put off though, installation is very simple and easy. First off this is not a cement grout and the working time is about 30 minutes, not several hours like you have with cement grout. After reading all the bad reviews it's obvious that they did not read the instructions and tried to use the same methods as cement based grout to install which resulted in a huge fail. Unlike cement grout, you don't need to worry about color matching when doing multiple batches because the color is in the Part C colorized sand which has consistent color. You don't have to worry that multiple batches will have different shades because the color always matches exactly with every other batch. Never mix more than you can install in 30 minutes!!! Once Part A and B are mixed the clock start ticking and the product starts to set. After about 40 minutes it's not fluid enough to work into joints effectively, in 3 hours the grout is very hard, and cured in 24 hours. (7 days for full stain resistance though) In contrast, cement based grout has a working time of many hours and takes 27 days to fully cure. This is an epoxy which has three parts, A, B and C. Part A is the hardener, Part B is the epoxy, and Part C is the colorized sand which is the fill and provides the color This kit includes Part A and B, but you need to purchase Part C separately. Parts A and B must be mixed exactly 1 to 1 plus up to 6.6 parts of Part C. The ratio of A, B and C is 1 to 1 to 6.666 for floors and 1 to 1 to 6 for walls. For walls you want to use less sand (10%) to make the mixture less firm and more sticky to make it easer to install on a vertical surface. Part A and B must be mixed 1 to 1 EXACTLY! Buy a cheap kitchen digital scale to mix everything together. A mini unit has 150 grams of Part A and B, and Part C is sold separately in a 1 kg package. If you need more than 2 mini units, buy a Full unit instead which is the same a 4 mini units but only slightly more than 2 mini units. Always work with small batches, just enough to that you can install the grout in about 30 minutes. A mini unit will do approximately 45 sq ft of 12 x 12 with a 1/8 grout line and you want to this in TWO batches. For a mini unit this would be 75 grams of Part A and B, and 500 grams of the part C sand. Walls are harder to grout and take more time and I would recommend doing at least 3 batches with 50 grams of Parts A and B, and 300 grams of Part C. (Remember use less Part C when doing walls!!) Larger grout lines means you use more product in less area which means it installs faster.so you can mix bigger batches and get it installed in less time. Smaller grout lines use less product but take much longer to install so you want to use smaller batches for grout lines less than 1/8 inch. I used this product on a bathroom remodel and used this on the floor and shower with a total of about 100 sq ft of tile. I purchase a full unit and did the install in 10 batches, 2 for the floor, and 8 for the shower. The shower walls are 12 x 12 on the bottom half and 3 x 5 tiles on the upper half. I did each wall half in a batch (6 batches), then the floor, and then the shower entry. There is zero color difference in any batch and it's impossible to see where one batch ended an the other began. I know exactly where to look and I can't see any difference or even tell that the grout was installed in multiple installs. It took more time (3 weekends) only because I didn't want to do multiple batches in a single day because of all the horror stories I read about using it. After the third batch and I got more comfortable with the product and did two to three batches each day and realized all the horror stories were from people that did not read the instructions. Here is a foolproof method for installation. Things you will need: stiff plastic brush, vacuum, kitchen digital scale, white vinegar, several sponges, hard rubber grout float, disposable mixing container (16 oz plastic cups work great for mixing a half mini unit or less), wood mixing sticks, two large buckets, two medium size binder clips (to seal the bags of Part A and B after opening them), latex gloves, white scrub pads, terry cloth or micro fiber towels (washed if brand new) Success is very simple: be prepared, mix only the amount you can install in less than 30 minutes, and proper cleaning. Figure out your batch size and how much Part A, B and C you will need. Remember never mix more grout than you can install in 30 minutes which for most installs is no more than a HALF a mini unit. Use a stiff brush on all the grout lines to remove any mortar from the tile edges to at least 1/8" below the tile surface. You can use a small file to scrape it out if necessary. Vacuum the grout lines and wipe down the entire area you are grouting with a clean sponge and plain water. The tile surface must be clean and all debris remove from the joints prior to grouting. To clean the grout residue from the tile you can use the cleaning agents included in the kit or white vinegar. Mix one packet of the cleaning agent in two gallons of water in one of the big buckets and toss in a sponge. It doesn't matter how big your batch is, you need to mix the ENTIRE cleaning agent packet or 1/2 cup of vinegar in two gallons of water. Put the bucket of cleaning agent and your grout float near the area you will be grouting. You want the first cleaning agent bucket ready BEFORE mixing the grout. First, weigh out the amount of Part C you will need put this aside. If mixing a half mini unit this would be either 500 grams (floor) or 450 grams (wall). Put on the latex gloves!. This stuff is sticky and while it's easy to remove with the cleaning agent, it sticks to your hands and fingers like peanut butter but doesn't stick to as well to the latex. Put the mixing container on the scale and zero it. Cut off a small corner on the Part A bag and squeeze it into the mixing container while it's on the scale until you have added exactly the correct amount of Part A. For a half mini unit this is 75 grams. Fold over the cut edge of the bag several times and use the binder clip to secure it. Zero the scale again. Cut off a small corner of the Part B bag and squeeze into the mixing container until you have added the same amount of Part B. (Fold over and secure with a binder clip) With the wooden stick mix the Parts A and B thoroughly scraping the sides and bottom to ensure that it is well mixed Part A is a clear yellow liquid and Part B is a pure white cream. You know it's mixed when it's a consistent yellowish off-white. This takes only a minute or two. Add about 75% of the Part C you measured out earlier and thoroughly mix. If you add all of the Part C now it will make mixing it in much more difficult. Add the remainder of the Part C and mix with the stick until consistent. This only takes a minute or two. Mark the time!!! Very important because you want to start the first cleaning in about 40 to 50 minutes from this time. Start applying the grout IMMEDIATELY!! After doing a small area, use the edge of float at a 90 degree angle to scrape as much excess grout off the tile as you can. Use the scrapings for the next section. The more you get off now, the easier the clean up in the next stage! This is where the working time of the grout is important. As the grout sets and gets stiffer, the grout will start to pull from the joints when you scrape. When this starts to happen your DONE with this batch! The warmer the room, the faster it will set up. You might have 45 minutes working time if is cool (less than 70 degrees) or less than 30 minutes if its warmer (more than 80 degrees). Don't use every last drop of grout, keep a very small amount to fill in missing spots you find during the first cleaning pass. Put the float off to the side for now. You can save some of the mixed grout for use later if you put it in zip lock bag (flatten and squeeze out all the air) and stick in the freezer. The freezer will significantly slow the curing time of the epoxy and it will stay good for about a week. After you have finished, check the time. You want to start the first cleaning pass after about 45 minutes from the mixing time. Usually this about 10 to 15 minutes after the batch has gotten too firm and starts pulling from the joints when your scrape with the float. The grout needs to firm but still very soft for the first cleaning. Mark the time when you start the first cleaning because you want to start the second cleaning pass about an hour after the start of the first. Wear latex gloves while cleaning with the sponge! The grout is pretty sticky and gloves make smoothing the joints with your finger very easy. Starting with the area grouted first, use the wrung out sponge to quickly wipe down a small area. The cleaning agent takes a few seconds to loosen the grout so you first just want to quickly wipe down the area you are about to clean and this makes the process faster. Use the sponge in a circular pattern to clean the grout from the tiles. Clean the sponge frequently in the cleaning agent until the entire area you grouted is clean. It doesn't have to be perfect, but you need to get the epoxy off the tiles and the grout lines looking almost perfect. Use the leftover grout to fill in any areas as required. Once the area has been cleaned, rinse the sponge in the cleaning agent and now your going to wipe down the entire area. One pass on each side the sponge and rinse in the cleaning agent. Overlap each pass. Very, important that you do only pass one each side of the sponge. Wring out the sponge as much as you can during this phase. The first cleaning is to smooth out the grout joints, get all the epoxy off the tiles, and remove most of the residue. About 1 hour after you started the first cleaning pass you will do the second cleaning. The first cleaning should take about 30 minutes so you will have some time to clean the float and mix up a second batch of the second cleaning agent. Throw the float into the dirty cleaning agent bucket and clean the float before disposing of the dirty cleaning water. Clean the bucket and mix a fresh bucket of cleaning agent with a clean sponge One full cleaning agent packet or 1/2 cup of white vinegar in two gallons of water. Fill a second bucket with just clean water and throw in third clean sponge. The sponge from the first cleaning might feel a little sticky which is ok and you can use it again as the first pass cleaning sponge for the next batch. When it feels gummy throw it away. I used the same sponges for same passes of each batch until the first cleaning sponge got gummy. The second cleaning sponge then became the first, and water wipe down sponge became the second pass sponge and the new sponge was for the final water cleaning. I ended up using 5 sponges for the 10 batches Wait until an hour has passed since you started the first cleaning pass before starting the second. By this time the grout should be very firm but still workable with the cleaning agent and sponge. Again do a quick cleaning with the wrung out sponge (wearing latex gloves). After this cleaning the grout lines must be to your satisfaction and all grout residue removed from the tile. You shouldn't have much to do during this stage but if you still have epoxy on the tile, you can use a white scrub pad to remove it. After the quick cleaning, Rinse the sponge thoroughly and begin the wipe down. Again, only one pass on each side of the sponge before cleaning it in the cleaning agent and overlapping the wiping passes. You want the sponge as dry as you can. Once this is done, immediately use a fresh sponge and the clean water to go over the tile again just doing a wipe down (wearing latex gloves). The goal hear is to wipe off the cleaning agent and any remaining epoxy residue and you want the tile as dry as you can. Again ONLY one pass per sponge side before rinsing the sponge. If your tile is highly polished with a mirror finish use a terry cloth or micro fiber rag to wipe off any excess water from the tile. Highly polished tile will show even the smallest amounts of epoxy residue and wiping off the water will remove any epoxy residue that might be suspended in the water. This will also remove any left over cleaning agent. Calcium based natural stones such as marble, travertine and some granite could etch if the cleaning agent is left on for long period and is not fully removed because it is slightly acidic. Sealers will prevent staining but are much less effective preventing etching which is a chemical reaction. No sealer can prevent etching. After about an hour and the water has dried from the tile you want to check to see if you have any epoxy residue left on the tile. Wipe your finger across the tile and check for residue, If you can't tell (which is especially true if you are using light colored grout) get very close to the tile and use a light at various angels to see if you can see a haze on the tile. If you there is residue use a clean micro fiber or terry cloth towel to see if it wipes off. If it doesn't use a white scrub pad and sponge with new bucket of cleaning agent and water and do another wipe down with clean water. If you have residue, you aren't cleaning properly and need to do a better job wiping with the sponge. One pass on each side of the sponge and rinse!!! Check for residue again in an hour. Residue will create a haze on the tile that is extremely difficult to remove after about 12 hours so it's very important to check for residue or haze before the epoxy cures. If you need to fix a spot you can use your cache of frozen grout. Freezing it doesn't reverse or stop the curing process, it just slows it down significantly. To see if your frozen grout is still good, break off a small piece and rub it between your fingers or hand until it warms up If it becomes sticky it's still good, but if it crumbles its cured and not any good. Keep in mind you only slowed the cure time so the working time of the warmed epoxy is only a few minutes. It's really only good for filling small areas. This stuff is water proof, virtually stain proof, much more durable and harder than cement grout. Yes it's more expensive but in my opinion worth it. The grout looks perfect and looks much better than any cement grout installation.
