Stain-Proof Plus Premium Impregnating Sealer for Natural Stone and Concrete Countertops

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.

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!

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.
