Lustro Italianoウルトラプレミアムストーンシーラー、8-1/2オンス

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.

Mode d'emploi vraiment pas claire. Mais produit pas pire

Seemed to do the trick (after using etch remover), but is has very strong fumes that lasted over a day. Use in a well-ventilated area.

Pretty good. Has a strong smell until it dries, but restored the surface

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.
