Miracle Sealant 511 Porcelain & Ceramic Tile Sealer – 16 oz. Spray Single

I’ve been searching for a long time to see if there was a product that could reseal my old porcelain sink. There’s no way to replace it unless I remodel the kitchen because it’s placed in concrete. Most of the products on the market are paint and scratches and doesn’t come off this product once you get your kitchen sink the bottom, clean, bleach, sustains out apply the coating effect I applied to let it dry for three days that time. No more stains. It’s been two months and I haven’t had any stains on the bottom of my sink. Fantastic product can save you lots of money.

I have a 20 yr old porcelain toilet that accumulates "film" (or whatever it is) in the bowl, necessitating a light/medium scrubbing with Barkeeper's Friend and the rough-side of a kitchen sponge, every week or 10 days. I thought that possibly "sealing" the porcelain would lengthen the time between needed cleanings.After thoroughly cleaning the bowl (making sure it was dry & kept dry), I applied the 511 Sealant and let it set for about 4-5 hours. (Granted, the instructions state it's best to leave it "cure" for 24-72 hours.) While it may have extended the time between necessary cleaning by a couple of days, I'm back to square-one. I will attempt to retry this product at a future date, when I can actually allow it to set/cure for a couple of days and see what happens (and will update my post if anything new/different occurs.)

We liked it

This sealant was recommended to me to seal the tiles after laboriously cleaning all the white hard water residue off the tiles I put on our fountain.Appears to do the job!

This product is supposed to be a tile sealant, so I purchased it to seal a tile that we decorated with inks. Upon reading the directions for this product, it is used to seal natural tiles and needs to be wiped off after it is placed on the tile(s). Obviously this is for a different use than the name implies. I also can't return this product because it is flammable. Quite disappointing.

Good product

Bleached the area thoroughly. Let it dry. Applied as directed. Grout started turning black in less than two weeks. It's far from a miracle. Very disappointed.

The clear coat on my old white porcelain kitchen sink had worn away, exposing the porous material underneath. The result was that every piece of food that sat in the sink for more than a few seconds left a stain that could only be removed with bleach. I was dubious that this sealant would help, but it helped immensely! No more stains from food and no more bleaching! The hard part was not using the sink for 3 days after application. But worth it.
