Lustro Italiano Ultra Premium Stone Sealer, Clear

I've not found a stone sealer I like while doesn't use strong solvent/VOCs. This is one of those. Good sealers will cover porous surfaces easily, with a slightly wet look, won't appear as a "layer", and will LAST. This is one of those. However, if you have any respect for your health, use a respirator. The 3M type for $35 will last you many years and is great for paint projects too. Do not try to get by with open windows. If you can't be bothered, use a typical low-VOC poly sealer. Which will sit as a layer until it eventually flakes away. I use this because it simply looks better. Also, the tin is over-sized so it will seem half-empty. That's normal.

This is a fabulous sealer. I used this on our marble bathroom (shower tile, counter top and marble floor) and it holds up very well. Easy to apply with a natural hair paint brush. Water drops bead and are easily wiped off.

I found a nice piece of furniture with a beautiful black marble top, but it had a lot of water marks and other etching. I looked around for various solutions, tried the baking soda approach with no effect, but decided to try the Lustro etch remover. I saw that it had mixed reviews, but was willing to give it a go.I found that even with half of hour of work in a small area it had virtually no effect. I tried 30 minutes twice in two different areas, but neither area was improved. It was also difficult to use, since it will make any part of the marble it contacts hazy. I figured I would try a light cleaning of the entire surface at once at the very end to remove the haziness, but since it wasn't removing any etching I gave up on it. I had also gotten the Lustro stone sealer, so I tried that in a small area to see if might cover the etching at all. It apparently sealed, but had no visible effect on the etching. I also tried using light oil in a small spot, which did help a little from some angles. A good paste wax also had no effect on the etching.Not wanting to invest many hundreds of dollars for professional polishing, I tried various other approaches and finally settled on polishing the entire surface with a 3M ultra-fine (7448) hand pad. This removed the polished surface completely, leaving a honed or matt surface. To do this, I used the 3M hand pad wet, first going in one direction (since that's easier) to remove all the polish. I then went over the entire surface with a circular pattern, to provide a more uniform surface. As you go, occasionally clean the entire surface and dry it completely to check on the progress. Overall, it took about 2 hours with the hand pad to do the entire 8 square foot top. One hand pad should do around 12~15 square feet. After thoroughly cleaning and drying, I let it sit for a day to completely dry. (marble is porous) I then put on a coating of the Lustro sealer, letting it soak in for five minutes before buffing it off. I did find that if the sealer dries too much, then you can't cleanly buff off the surface, leaving a very mottled and smeared finish. This happened to me, (and other reviewers) but I found that re-applying the sealer, letting it sit a minute, and then buffing it off fixed it. Use in a well ventilated area, the VOCs in this are pretty nasty. After it was sealed, I tried the paste wax again, which did bring up the shine. The photos (taken from the same area, 3 with the same lighting) show the progress. The last photo shows how it generally looks in real life. Not as dark or vibrant as polished, but now that it is uniform soft finish it looks much better than all the water stains and etching.Hopefully this report gives others some ideas of how to proceed with their projects. My suggestions- if you love the polished look, and have anything other than very minor etching, call in the professionals. If you want to switch to a honed look, that is relatively easy to do yourself.

I like it because it does seal whatever you put it on. I used it on some ruined Corian sink and on a Marble cutting board. It sealed the pores and gave it a satin finish. Nothing shiny, but soo much better and it now prevents those horrible stains I was fighting every time some water got on those porous surfaces. I am very pleased! I did not use the etch remover, the chemical composition of the etch remover scared me and I sent it back. Just using this product worked just fine for me.

I used a foam roller to apply. Waited the instructed 5 minutes and went to wile it off. It left spots. I dried it as dry as I could, thinking a second coat would help. Nope, it is now shiny, but spotted. Grrr

works great you do have to work it on the stone

Why did you pick this product vs others?:Description on website.Functionality:Total waste of money and the smell is horrendous.

We got a new kitchen island from a ~10 year old piece of granite that had been in a showroom. We had the installer polish it and got this stuff to seal it once installed. We applied as directed, made sure the granite was clean and dry, I bought a small spray bottle and poured this into it and sprayed it on. Waited a few minutes and wiped off the excess with paper towels. I was not sure if it was really penetrating. I read some reviews that said to apply two coats so I waited a few more minutes and did it again. This time I don't think it penetrated at all. I wiped and wiped but a white film was left behind. My wife and I took turns rubbing "assertively" for a few minutes at a time and it just seemed like we were smearing it around. The granite had a slight but unmistakeable stickiness that we couldn't get rid of. Finally the next morning I cleaned it with Windex and it seemed to clean up ok. It had an ok shine but after all that I don't think we really changed it at all.Maybe this stuff is intended for marble or more porous types of stone, perhaps the granite is too hard or impermeable to seal. I have read a fair amount about all of the liquids sold to polish and seal marble and granite and many people think these are ineffective and a waste of money. Not saying that this stuff is worthless but in our case it did not seem to do any good.
