Miracle Sealants511 Porous Plus Premium Countertop, Stone, and Tile Sealer, Quart

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.

This product works well. It is not cheap, but was necessary to protect my new travertine pavers by my pool. I ended up purchasing (5) bottles to cover all of the pavers twice. The manufacturer’s directions call for wiping excess off the surface after 3-5 minutes. Considering the price, I wasn’t about to wipe any of it off. After a moderate rain, water was clearly beading nicely.

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).

Very durable, quick drying, easy to useWorks great on ALL my tile. especially in shower “ pebble stone” floor- Odor not bad & goes away quickly

We have soft natural stone in our shower, and this product creates a great water seal. We tried other products and they did not last long. Three coats of this and water naturally beads on the surface. Easy to apply. After six months the stone does not absorb water. Excellent.

Great product that just works. Wanted a porous sealer for our arctic white marble pool deck. Seems like we just look at these pavers and they stain from everything from just dirt to pine needles. Did not want to change the appearance to have any gloss or darkening. Applied yesterday and completely satisfied with results See before and after photos of water sealing after first coat and plan to do 2 as instructed. Only need to see if this product lasts

Disappointed in the product. I have used the regular 511 and contacted the company as to whether this would be a better choice for my natural stone tile shower and was told it would. I applied 3 coats while letting dry in between for maximum benefit but wasn't impressed. The regular 511 was far better at preventing staining and keeping the shower cleaner much longer. It was very expensive for a small container and not impressed.
