Stain Proof Premium Impregnating Sealer - 1 Quart, Protects Against Stains, Water Damage & Dissolved Salts, Sealer for Granite, Marble, Tile & Stone; for Indoor & Outdoor Application (1-Pack)

I finally bit the bullet and steam cleaned about 900 square feet of tile/grout. By using a rolling dispenser bottle the sealer went on easily. I rolled it on in sections so by the time I was done doing that I could go back and wipe it down with a clean white rag. The grout was several years past needing maintenance but looks like new now! Time will tell if it helps protect against stains and grime.

We used this on our honed marble counters. We've had marble before, but this particular slab seemed very porous compared to the counters we'd had in our previous place. Those were also polished, which I think helps with the staining. These new counters were showing every water spot, and every drip of oil was staining them! We wish we had ordered the sealer and sealed them immediately, but based on our prior experience we didn't expect them to be so porous! We cleaned the oil stains by letting a combination of hydrogen peroxide and backing soda sit on the stain for 24 hours. When we applied the sealer we had to be out of the house, with all door and windows open and fan on, because the fumes were very, very strong. We applied and re-applied per the directions, and now our staining issues are totally gone. The stone is not impervous (an unnoticed spill of coffee under our coffee maker created a stain, but it sat there for probably a week, and we were able to lighten it with the aforementioned strategy). 98% of spills, even if they sit for 24 hours, have come up with no staining which is quite an improvement and we are very pleased and relieved that this sealer works so well.

The best sealer. Lasts years. Easy to apply. The jar goes a long way. No residual effects to the finish. Vapors are probably very bad for you. So ventilate when using.

REALLY expensive, but it works better than anything else I've tried.... and protecting a large investment

Easy to apply and it works as specified.

Perfect sealer for our granite counters. The amount in the container is good for many recoatings.

Works great on flagstone coping around pool. Used standard spray bottle from HD. If you use a microfiber covered sponge you can spread the product around and get about 840lf of 12” cooing and the pool edge out of one quart. When pouring into the spray bottle, the product will foam so pour slowly and let it settle or you’ll be spilling $$ on the floor. Note: I sealed the coping before pool had water in it. You don’t want any overspray to get into the pool water due to contents of the chemical. Once pool has water you’ll need to sponge it on.

Works as expected.

It was all good

As advertized.

Doesn't work as described

Este es el mejor sellador , probé muchísimos y todos cambiaban el color del mármol donde lo apliqué y este dejaba exactamente el mismo tono blanco y además es muy resistente . El proveedor de este producto me atendió de una forma rápida y con ganas de ayudar ! Los felicito por el servicio al cliente que tienen !!!

Used it to apply on grout - floor and bathroom tiles. Application is tricky - it requires a squirt bottle with tiny hole. Excess will over flow on to the tiles - Use paper towel soaked in isopropyl alcohol to remove excess. Reapplication over itself will undo it or make a mess! Let it set/dry for more than a day!
