Review: Excellent product - Purchased other sealers from other sellers, and they did not work on my sandstone table tops that I make and sell to furniture stores. This sealer works, only need 2 coats.
Review: Sealed natural stone. Water beads up now. - 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.

## Questions & Answers

**Q: What is the difference between 511 Porous Plus Penetrating Sealer and 511 Impregnator Penetrating Sealer? I need it for concrete kitchen countertops.**
A: I used two coats of the 511 Impregnator Sealer on the white grout between my porcelain floor tiles in my kitchen. Despite frequent cleaning,  it wasn't long before the grout became discolored, until now where it is black. Would the 511 Porous Plus be more effective in keeping the dirt out of the grout? If I should apply the Porous Plus, how do I prepare the grout after I clean it?

**Q: How many sq feet does a pint cover?**
A: It depends on what you are sealing. For slate, flagstone and Saltillo about 250-300   sq. ft.  per quart.  For polished stone--granite, marble --likely 1000 sq. ft. per quart. For slate I use about 1 Qt. per 300 sq. ft. A bit more with Travertine. It does a great job. I recommend their cleaner prior to sealing. A Pint of the cleaner goes a long way. Hope this helps.

**Q: How do you use this?**
A: I used this to seal marble tile and grout. I had used another product in my other shower which worked fine with my kitchen granite counter tops, but marble and grout are more porous. After applying this product two time with paintbrush and then wiping down five minutes afterwards with moist towel, my shower was sealed real nice. I even went back and re-did my other shower. I found it best to pour a little bit in cup and apply in uniform direction with brush and wiping down in same direction. This stuff is top notch, but open a window or turn on an exhaust fan as it has a potent smell.

**Q: Can this be used effectively on a slate floor?**
A: According to the instruction label on the back of the product, yes, it can be used on a slate floor.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product
*by V***Y on November 26, 2025*

Purchased other sealers from other sellers, and they did not work on my sandstone table tops that I make and sell to furniture stores. This sealer works, only need 2 coats.

### ⭐⭐⭐⭐⭐ Sealed natural stone. Water beads up now.
*by E***N on July 2, 2025*

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.

### ⭐⭐⭐⭐⭐ Works on Kashmir White granite
*by C***E on April 10, 2021*

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.
