511 Porous Plus 473ml (US PINT) The Best Performing Penetrating Sealer on the Planet

Good product although expensive

it does what it says

2/2022: my shower and bathroom are still well sealed. I still haven't gotten around to the kitchen grout yet but I will definitely be using this product. The water still beads up on the bathroom grouts. 2019: I bought a pint to use for my shower tile, floor in the bathroom, and my kitchen backsplash and window sills. I finally got around to the shower yesterday. I used a foam craft brush to apply to sealant. I don't recommend that form of application because it caused a lot of foaming. However, since I didn't have anything else to use I continued with it. I applied the sealant as per the directions. Let it sit about 3 - 5 minutes and wiped it off the tiles. I only needed to seal the grout as the tiles didn't need to be sealed. After I sealed the grout in the walls I sealed the floor grout. I have a pebbled floor and again, just needed to seal the grout. After I completed the floor and wiped up the excess I waited about 2 hours and repeated the process. The smell didn't bother me until I sat in the living room after completing the task. I got a sore throat and my nose became plugged. I closed the bathroom door and lit a candle in the living room. That took away the odor. This morning I couldn't smell it at all. I dripped a little water on the shower floor and wall and it beaded up perfectly. I had to order a quart more so I can do the remaining grout areas. As soon as it arrives I'll finish the bathroom floor, kitchen backsplash and window sills. Ok, it's been five days since I sealed my shower and I STRONGLY RECOMMEND TO WEAR A MASK. I have had a sore throat and nasal passages since about 6 hours after using the product. Now, that's completely my fault because I read the directions and they clearly say to wear a mask and open windows and doors and use the fan if you have one. I sealed the bathroom floor grout yesterday. I really like how the water beads up now! Next will be the kitchen grout! I highly recommend this product. Other than needing a face mask and opening windows and turning on the fan, it's a wonderful product.

No protege..está muy caro....

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.

Really like the product. Water pills and rolls right off.

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.
