Lustro Italiano Ultra Premium Stone Sealer, Clear, 8 1/2 oz. (Packaging May Vary)

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.

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 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.

Used this on my carrara marble kitchen table that is several years old and the sealer must have worn off because it started to get scratches and began getting water stains from glasses. I used the etch remover to remove those as best as I could and then sealed it with the sealer. The sealer really worked well to hide everything and really does seal the table! If you put water droplets on it now you can clearly see it bead. I honestly don't understand how others can say it doesn't work. Have you tried the bead test? You are not suppose to notice a plastic coating on the top of the table or counter! It is a natural stone and a natural sealer. You aren't suppose to see anything. The product is suppose to penetrate the stone and protect it, which it does.

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

DO NOT USE ON YOUR MARBLE!!!!!! DO NOT MAKE THE VERY EXPENSIVE MISTAKE I MADE!!!!! I hand polished our marble with a different etch removing product. It restored it to a great gloss finish that I was very happy with. It was recommended that I seal the marble to prevent etching, water marks, and damage. I purchased this and their etch remover in a package on Amazon. i deeply regret using the sealant. It would foam with 4 different clean new application methods (foam brush, cloth, paper towel, microfiber). I kept re applying in hopes that it just needed some more to create a clean smooth finish. It never did. I followed instructions on the container. Researched online. And did everything I could find. Nothing worked. Now I can’t return the item because it’s a non-returnable chemical. And my marble is severely damaged and will need professional cleaning/resurfacing/polishing/resealing. Which as you may know, can cost hundreds and even thousands of dollars. Never buy this product. Please. Don’t be like me.

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 chose this product because it was a recommended by a home improvement sight that I trust. It also comes in a small quantity and my job was just a small one. It applied easily and dried as described. It is protecting my marble well but it is too soon to make a prediction about it's longevity. It had a quite strong odor when applied and needs to be used in a well-ventilated area. Once dry there is no lingering odor. I recommend this product.

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.

does not do what it is supposed to do. messy and ineffective

After applying the sealer with a brush following the etch removal step with the same product, the sealer has left streaks on my marble table. It is very disappointing.
