Lustro ItalianoUltra 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.

works great you do have to work it on the stone

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.

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 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

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.

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.

Pros:- It should work if you have the proper equipment.Cons:- The smell, you should open your windows when doing this as the smell is really strong.- Unless you're dealing with a very small space, you will need a buffer to make this work.I used the etch remover from this brand and it worked really nicely and that's why I decided to buy the sealer from them to seal and protect my marble countertop.I followed the direction and used a brush to spread the sealer evening across the counter top and waited maybe 4 minutes before I started to wipe them off, but it left a trail. If I scratch the trail with my nails I can feel the sealer come off but its everywhere and will take a while for me to clean it all off now. I suspect that this will work if you buff it with a buffer but wish I knew that before using it.
