Power Grout Dove Gray

I have used this product on 5 projects now. The first time I used it I didn't follow the directions; I am used to working with mortar and grout and have always been good at judging when enough water has been applied during mixing... You can't do that with this product. DO NOT ADD MORE THAN THE RECOMMENDED WATER VOLUME! If you add more than the recommended volume of water the grout will not harden completely. It will look hard, but as soon as it gets wet it will wash away... Not fun, I removed grout for 16 hours. After talking with my local supplier I decided to try again, but this time I follow the directions on the bag exactly. I have been very happy with the results, enough so that I have used it on four more projects. I'm not convinced that it doesn't require sealing, but it is highly crack resistant and that is what I needed more than anything.I'm giving it 3 stars, not because it isn't a great product, but because the product is very unforgiving when not mixed to very exact specifications.

I'm providing this review after using the product on 600 sq ft+ of 12x20 floor tile and stone mosaic shower tile. I appreciate the frustrations and disappointment expressed by other reviewers and how hard a redo of a job that must have been, but my experience is not the same.I bought this product elsewhere and it worked well - it does set up fast, the color is uniform throughout, and it's a bit harder to clean up compared to "regular" grout. I am a DIYer but I had some training from the pros (hopefully I remembered most of what they taught me).My grout set up in an hour and you could walk on in a 4-5 hours for both jobs. I just did the shower floor yesterday, finishing up in the afternoon and its hard as a rock the following morning. The 600 sq ft living room job was completed a few months ago and looks great.The ONE DETRACTION I experienced is that the grout requires sealant. The living room grout will absorb water (and stains), so I sealed it.The pic below is the 3x5 shower floor after 12 hours. Take note that the tile is still "dirty" as I didnt clean it promptly. Im going to wait a few days then use a gentle-ish tile cleaner and seal it. Should be fine.

This is a terrible product and I strongly caution anyone against wasting their money on it!First, the color did NOT match the color sample I chose it off of! I also purchased a tube of sanded caulking by TEC to match the color I had chosen (which was Sable) and the caulking is SEVERAL shades darker then the grout!!! Both have had adequate time to cure. You can see the significant contrast in the photo I added. Caulking is the darker, horizontal line between the granite and the travertine mosaic. The caulk matches the color I chose!Second, this grout was nearly impossible to work with! I am a DIY homeowner, maybe the pros know tricks, but this grout began to set up in my bucket within 45 minutes of mixing it! It sets FAST once it starts and I could hardly work it into my grout lines at all! I mixed only a portion of the bag at a time; I had to continue adding water to be able to manipulate the material at all; and I had to entirely dump one of my batches after fighting to get it applied fast enough!Third, it DOES require sealing! After 3 weeks, I was still able to wipe off significant amounts of grout from the lines with a damp towel, and it was soaking up everything it came in contact with! I gave it 48 hours to cure before I used the surface, and it began showing lighter colored stains throughout the applied area within a few days!I used this grout on a granite tile counter top and am SO frustrated with this product! It was extremely expensive. I knew I needed to invest in a good grout, but this material is a SCAM! I purchased it from a local flooring retailer at the recommendation of the staff, AND STRONGLY REGRET my choice! None of the promises made by this manufacturer on their label were delivered!

Where do I begin?Everything advertised about this product is not an exaggeration, but an outright lie! I had 800 square feet installed (instructions followed to a "T") -- two different areas with two different colors. The first installation -- the grout color came out pink instead of the purchased light smoke. Upon closer inspection of the original bagged cement powder and contrasting it with the TEC color stick as well as light smoke regular TEC grout -- it was indeed pink and not the needed color. So a call was made to HB Fuller who told me that they would send me both an acrylic bonding agent (which turned out to be in fact an acrylic sealer) and a color sealer product -- thereby negating any advertised benefits of using their product in the first place and causing extensive rework. Upon talking to the color sealer manufacturer, I found out that it would be disastrous to apply the acrylic sealant (sent to supposedly seal in the bleeding color) before using the color sealer product. Fortunately, I investigated this beforehand. Note: This product when dampened even with a drip of water causes efflorescence if it is not wiped up immediately. The grout is extremely porous - water bead doesn't just absorb but any water will run the length of the grout and soak in.So, onto the second application. Same problems except the color was as described. For added protection and after a week's curing time, 511 impregnator sealer was applied (one of TEC's recommended compatible sealers) -- three coats and it still continued to fully penetrate the grout so in all likelihood it just sealed the subfloor! The grout still bled color and showed efflorescence from minute drips of water after 96 hours. Now I applied the acrylic sealer (as a water-based sealer can be applied atop a solvent-based sealer). Two coats later, it adhered well -- HOWEVER, water could still penetrate and the grout still bleed color. Now I have to attempt to strip all and do another color seal job.It's said that a good tiling job is 5% the tile and 95% the grout -- well, the opposite is true in terms of cost. Over $7000 worth of material and even more in labor ruined by $180 worth of the WORST GROUT PRODUCT EVER!
