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

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.

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.

Follow directions. Best on the market

I hope that this product works as advertised. I use part of it on my new kitchen granite countertops. I didn't like the fact that the product was not sealed when I received it and no way to know what is inside.

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.

A key product if you are redoing your tile.

This stuff sure is stinky but once it’s set it’s amazing! I highly recommend sealing countertops and backsplashes if you have granite before you use the kitchen for good.

Followed directions perfectly. A few months after applying an energy drink was splilled and it left my countertop dull and rough. I have noticed many other water rings and etching. I take very good care of my countertops and do not let anything sit on them long that could cause damage. Too late to get a refund. Waste of money.
