Stain Proof Dense Stone Impregnating Sealer - 1 Pint, Protects Against Water and Salt Damage and Oil-Based Stains, Sealer for Granite, Marble, Tile & Natural Stone; For Indoor & Outdoor Application

Second update Dec 2022: Water still beads. Did not expect this. No coffee, soy sauce or or ketchup stains. Hope it stays this way! Update Dec 2020: Three months later, the coating still beads up water on our marble countertops. Stains such as ketchup, oil, soy sauce wipe away easily, even after leaving it on overnight. Original review: Bought this to seal our super white marble kitchen countertop. We like the look and feel of natural stone formed over many years (or million of years) - the marbling and patterns cannot be matched by quartz or porcelain. We were aware that marble will stain and etch but still decided that the trade off were worth it (for us). To reduce visible etching, we honed our marble - this first step reduces the visibility of etches. If you have marble- no sealant can prevent etching - a chemical reaction. These sealants help against stains such as oil and water. Acids will still etch a marble countertop. If you cannot bear to see etch marks- either use a different stone or have a contractor rehone or re-polish the surface every few years . Our installer applied a generic sealant when they installed our marble countertops. Told us that we should continue to seal the countertops everyone 6months to a year - or when water stops to bead on surface. This seems like a lot of maintenance. Found this product on Amazon and looked up reviews. The company have been around for a long time and their products were used to seal surfaces (mostly marble or concrete) such as in the Sydney Opera House and Dallas Cowboy Stadium - I guess, if it’s good enough for these world class commercial venues , maybe it would work in our kitchen. I found a 2 hour long video where their sales rep demonstrated their products to contractors on YouTube explaining how it works and why it is supposed to last many years . I also found a review on a British site on the “non plus” version of this sealant - they did a test on stone flooring with follow up after 4 months - their verdict was that while it was very good - there were still visible stains. I carefully read the instructions and applied using lambs wool pad waiting for it to slightly dry in between the first and second application - about 15 minutes. It does smell as the solvent is strong . How bearable it is - depends on who you are. If you have used solvents to clean your paint brushes or rollers- . it smells about the same. We opened our windows and ran our range hood for a few hours. Smell seemed to clear after an hour or so. After 12 hours, smell seems to have gone.. I would hesitate applying this in winter without adequate ventilation due to smell/ high VOC content. We did two applications and buffed it after the second application. From one of the YouTube videos, the manufacturer sales rep mentioned to use a microfiber cloth for the final buff - seems to be a “secret” to removing the solvent. Another video mentioned that it dries to touch after 2 hours , and not to wet the surface for at least 6 hours. The surface can be used after 12 hours . The solvent acts as a carrier to allow the sealant to penetrate into the stone to protect it. So after the product is applied, most of the work is actually inside the pores of the stone . Attached is a photo of our countertop after 12 hours of drying time. Left a few drops of water on countertop and it beaded up, more important, the marble did not darken , showing that it is already working after 12 hours. The actual curing time is supposed to be a few days. Will see if it really works after a few months. All in, it is easy enough for a DIY application, just read the instructions carefully and be prepared to ventilate. Seems expensive for a small bottle but if we only have to do it once every 5 to 10 years or longer - worth the trade off.

I just sealed about 70 sq ft of leathered quartzite in a couple of hours. It was much easier to use than I expected. I got it fairly wet on both applications and it only used about one fourth of the container. I guess marble and granite soak up a lot more than quartzite. It leaves a matte appearance that looks like bare stone with nothing on the surface. If that's the look you want this sealer is for you.

Only product I use on my Granite and other natural stone products.

We installed a marble top vanity when we redid our bathroom. It's a beautiful vanity, but we found out the hard way the marble top wasn't sealed, if at all. My husband also sprayed some harsh cleaner on the top, unintentionally, which naturally caused a mild meltdown since I thought this ruined our new vanity. For pete's sake, we only had this vanity for 2 months! and it wasn't cheap! My oil free face soap even stained the top! It was the last straw when I applied lotion to my hands in the bathroom several minutes before and TOUCHED my counter top and left four finger marks on the top. I researched and researched, and spent a good amount on products that removed the existing stains and etch marks from the abrasive cleaner (0000 steel wool and elbow grease will remove those light etch marks, if you're looking for an easy fix). Before sealing I removed the stains and etch marks (this is a must otherwise you will seal in your stains/marks). Anyway, onto this sealer! You need a not harsh spray top to attach to the bottle to apply. It has a strong scent it's very citrus-masking-chemical-smelling, so I used a mask and had our vent on full blast with the window open. It's very easy to apply, I used gloves and a clean lambskin rag. I followed the instructions, liberally spraying it in one area, wiping it to spread evenly across each area at a time. When finished, I set a ten minute timer and repeated the process the second time, set another ten minute timer and removed any excess. We did not touch the counter top for 24 hours. At the end of the 24 hours, to be extra sure it was sealed, I applied two more additional coats and removed any excess again. We waited an additional 24 hours before using the vanity (48 hours total). So far, after sealing, we haven't used our counter top much (but invested in a good marble safe cleaner). I've noticed water beads up on the surface now, which it didn't do prior. I'm hopeful it will keep minor oil/cosmetics from being absorbed into the surface as well. I'm thankful for a somewhat cheap and easy product to help save my marble top! I plan to reapply this yearly to maintain our marble counter top. I'll try to update this review in a few months and see how this sealer really holds up and protects over time.

this was recommended by my countertop installer. this is the best way to seal your countertops. it will last for years. you just need to clean your countertops every now and than to keep the counters clean,

The most long lasting and effective sealer of at least a half a dozen that I've tried. Open all the windows before you open the bottle.

My cabinets had a little sealant left in them, but were absorbing water (I especially noticed it under my rubber dishmat - the granite was quite a bit darker). To find out if your cabinets need to be sealed, you can do a water test (Googling will tell you how to do it). Sealing your cabinets when they don't really need it, could give you a streaky mess. Two of my cabinets needed less sealant than the others. The ones that didn't need as much sealant were harder to buff clean / streak-free. I did quite a bit of research to find out what the pros use to seal granite and this was hands-down the top choice. What sold me was that it would last 15 years—I have no desire to seal my cabinets every year. I measured the square footage of my cabinets and, based on what the bottle said, 1 quart would be enough. It was actually more than enough (my kitchen is pretty big) and I'm using the extra to seal the grout in my kitchen and laundry room. How much your granite absorbs will probably depend on its density and how much sealant it already has on it, but I had about half a bottle left over. The sealant was easy to apply—I degreased my counters first with a mix of distilled water and denatured alcohol (50-50). I applied three coats of the Stain-Proof with a handiwipe, waited 10+ minutes between each coat and then buffed the excess off with a lint-free dish-towel. I let the cabinets cure for 6 hours without getting water on them (covered the counters with dishtowels to make dinner)—the bottle says they're fully cured in 24 hours. I've noticed a big reduction in the amount of water the cabinets absorb (they don't even get dark under my dishmat anymore) and they are very easy to clean (I've been using a 30-70 mix of denatured alcohol and distilled water in a spray bottle + paper towel)—no streaks, no residue. I've added a picture of water poured on the surface. I sealed my cabinets 1-2 months ago.

I have a renovated bathroom with white honed granite (unpolished) that needed to be sealed. This sealant went on well with a brush but in seconds, began turning the granite a deep but pale yellow. I immediately panicked but fortunately after the 12 hour set time, it dried and sealed back to nearly its original color. It did make the granite a slightly darker hue of white, but looks great and water now beads off instead of soaking into the stone. Make sure to test in inconspicuous area, especially for honed stone to make sure results are satisfactory.

Easy to use and excellent results

Great thanks. Looks heaps better. The marble restorer should have given the marble another couple of coats in the first place for a maximum improvement ! The product was easy to use. Pity I couldn’t apply it earlier!
