Drytreat 110712 Stain-proof Plus, 16 fl. oz. by Drytreat

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

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,

Purchased this at the recommendation of an expert with the manufacturer who talked me through applying it to our Quartzite countertops. It's important to get the right sealer. Some contain color enhancers which you do not want with Quartzite. They have an instructional video online-Dry Treat Stain Proof Application Instructions by Chemical Concept. I poured the sealer a little at a time into a 12 in. Plastic Mud Pan with Steel Edges then dipped a 10 in. Lambskin Stain Pad and moved it smoothly in one direction across my countertops, let it almost dry, then at a 90 degree direction. After 2 applications in most areas, 3 in high usage areas, we let it dry for 15 minutes to a haze then wiped with Microfiber cloth. We waited another 24-48 hours before using the countertops. We tested before and after with water and after, the water just sat on the surface. After applying it to 70 Sq Ft of Stone, I still have quite a bit left over for a future re-treatment. Very pleased.

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.
