This will seal Kashmir White Granite when nothing else will. I’ve tried a number of “good†sealants on our bathroom counters, yet the counters continued to stain with anything that wasn’t pure water hitting them. I was almost to the point of pulling the counters in favor of quartz, but searched many stone forums and read reviews here on this product. Other reviewers here proclaimed success and their pictures showed they had this particular stone too. So I decided one last try was in order.I bought a stone poultice and went to the lengthy trouble of removing all the soap and lotion stains first (after using denatured alcohol to remove previous sealers), then treated the granite THREE times with this 511 Porous Plus sealer. It took three tries to get water to bead up. It was the first time water had ever beaded up on that stone! I poured some in a plastic cup and brushed it on with an old paint brush, waited the recommended time (maybe a little more), wiped up the excess with paper towels, and buffed dry with an old washcloth.As another reviewer mentioned, the sealer does bring out pale mica flecks inherent to this stone. 511 PP seems to not only soak into the stone, but also leaves a clear barrier on top. To my eyes this gives the stone more dimension, sort of like what happens when you put a worn stone into water to bring out its beauty. Use this one, not the regular 511 sealer available in your local big box hardware store.Anyway, it’s been a year since this adventure and I’m back buying another bottle to retreat my counters. This will be a yearly to-do in this house. The water is still beading up in most places, but there’s no way I want to go through the hassle of my initial poultice procedure. We were out of that bathroom for a couple weeks while that was going on. BTW, if you have a granite choice, NEVER choose this particular granite. It’s basically super-compressed limestone and as naturally porous as your concrete garage floor. Evidently with granite, the darker the better for resistance to staining.

I'm not going to lie, this product definitely smells like it is giving you cancer, but wear a bandana, open all the windows, and do as your told. Follow the directions on the product, and you'll be just fine. I'm no pro, and I wanted a lot more context before I got started, so I youtube'd a few tutorials for tips and considerations before I got started. Let me sum up what I learned from the process here:0. Open windows! Turn on fans! Wear gloves, safety glasses, and a bandana. Don't be a dim wit and just take in those chemicals like they're nothing. It's awful stuff.1. Make sure the surface is clean to start. Vaccuum, wipe down with a clean rag, brush or other, and make sure there's no leftover grout residue dried on the stone.2. Apply before or after grout. I was mortified to find advise online that you should only use sealer before grout. Not so! I consulted my tiler, and went ahead, and my job turned out fine. The tiler used an epoxy grout that doesn't require grout sealant, and maybe that's more resistant to discoloration or whatever the concern might be for not sealing post-grout.3. Just make sure to TEST the sealant on your tile and/or grout first, per application instructions, to ensure you want to use this product on your surface. There may be some color shift, darkening or other depending on the material, and you just don't know, so TEST.4. Because you need to wipe up 3-5 minutes after applying, I took small square sections at a time that I knew I could cover consistently within that time frame. I set the clock after one section, moved onto the next, and when the timer went off, I reset it for the new section I'd just finished, backtracked to the previous section to wipe up, and repeated that process until I finished the first coat.5. After 1-3 hours, repeat step 4 for a second coat. It was an entire evening's worth of work, but the result is awesome. I have a white marble backsplash that I hadn't sealed for the first few months after my kitchen remodel, and I was constantly nervous about staining it. Now I'm worry free! No filmy residue, just my beautiful, stain resistant tile.6. Finally, throw out any rags you use after the fact. The packaging suggests washing brushes with mineral spirits when done. Double scrub your countertops and anything you touched with the stuff after the fact (except of course your tile surface).

Follow all the directions to be sure it covers evenly and thoroughly. Have had several rains and it actually beads up. Used it on silver travertine pavers around my pool. No change in appearance. This is expensive stuff but it works. Measure accurately. Two coats. Hope it last years as label states.

Purchased for use on travertine shower floor tiles. The tiles were put in 4 years earlier and were sealed with a different product from the same company. Results with this product are night and day. Absolutely no water is absorbed into the grout or tile and the water beads. I used to need to deep clean about every two weeks, now a light cleaning along with a quick squeegee after use keeps them looking great. 100% will use again and will use as a grout sealer for my other bathrooms also.

We bought a new house and it was recommended that we seal it. We tried the miracle sealant, and it worked wonders! It was super easy to apply, and it gave our countertop a nice, fresh look. It’s been a few weeks, and it’s holding up great against spills and stains. I’ve noticed it makes cleaning up so much easier too, spills just wipe right off. The sealant feels like it’s giving extra protection. So if you’re looking to protect your countertops and keep them looking good, I definitely recommend this stuff. It’s worth every penny!

It is indeed very good sealant.Application is easy and quick. Gets quickly absorbed. Therefore, surface can be used pretty soon. It did make the old concrete blocks look much better.It is a little expensive for the quantity you get.

I have natural stone tiles on my kitchen wall, behind the stove as a backslash as well. The contractor was just not professional enough to know that this was supposed to be treated with sealant to prevent the oil and other stains being sucked up by the stone what ended up on the wall while cooking. I have not spilled anything directly on it but it is normal when food is boiling on the stove to have humidity and stuff evaporate...A have suffered removing the residue. Didn't dare to cook again and ruin the wall again.After I have treated the tiles with this product nothing sticks in/on the tiles any more. I can truly recommend. Would do the job with paint and kitchen counter as well. However it made the color slightly darker, which I do not mind. Its nice and even.
