Review: Repels water somewhat. - My wife forced me to install unfilled travertine in our tub/shower walls and after grouting the tile and holes I sealed with this stuff. 2 coats. Grout and tiles darken but when the sealant dries/cures the grout color returns. Maybe overall a bit darker than before sealing but looks better, without looking rich like some sealers that "enhance" the tile and grout for that always wet look. I'll have to seal every 6 months or sooner but that's because of the tile choice we made. Good product. Review: Works on Kashmir White granite - 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. ## Features - SCS Certified INDOOR ADVANTAGE GOLD - Superior Stain Protection - Superior Coverage - Interior & Exterior Use - Weather Resistant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000VX97SM | | Best Sellers Rank | #19,559 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #70 in Hardware Sealers | | Brand | Miracle Sealants | | Brand Name | Miracle Sealants | | Color | Clear | | Compatible Material | Stone, Terracotta | | Customer Reviews | 4.5 out of 5 stars 1,327 Reviews | | Global Trade Identification Number | 00753927511264 | | Included Components | Penetrating Sealers | | Item Dimensions | 5.2 x 5.2 x 2.3 inches | | Item Form | Liquid | | Item Type Name | Penetrating Sealers | | Item Weight | 1.8 Pounds | | Item dimensions L x W x H | 5.2 x 5.2 x 2.3 inches | | Manufacturer | Rust-Oleum | | Material | Water | | Material Type | Water | | Model | PLUSQT6 | | Number of Items | 1 | | Part Number | PLUSQT6 | | Style | Sealant | | Style Name | Sealant | | Surface Recommendation | Tile | | UPC | 753927511264 | | Unit Count | 32.0 Fluid Ounces | | Warranty Description | Satisfaction guaranteed up to 20 years from the date of purchase to the original purchaser. | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Miracle Sealants - **Item Weight:** 1.8 Pounds - **Item dimensions L x W x H:** 5.2 x 5.2 x 2.3 inches - **Material:** Water - **Style:** Sealant ## Images ![Miracle Sealants 511 Porous Plus Premium Countertop, Stone, and Tile Sealer, Quart - Image 1](https://m.media-amazon.com/images/I/71tgck60erL.jpg) ## Available Options This product comes in different **Size** options. ## 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 ### ⭐⭐⭐⭐⭐ Repels water somewhat. *by B***L on March 28, 2026* My wife forced me to install unfilled travertine in our tub/shower walls and after grouting the tile and holes I sealed with this stuff. 2 coats.
