Lustro ItalianoUltra Premium Stone Sealer, 8-1/2-Ounce

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.

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.

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.

After I removed the stains and buffed out the etched marks I used this sealer on my marble countertop in my master bath. Marble is porous so it took 3 or 4 applications to seal it well but it's sealed. In my opinion the best way to apply the sealer is to pour a small amount on to the counter and use a soft rag (I save old undershirts for this) to wipe the counter with the sealer. Wait 5 to 10 minutes and wipe off the excess or if you see streaking, apply another coat. 6 hours later your counter is ready to be used. I tried apply I got the sealer with a foam brush but that didn't work well for me.The sealer was easy to apply as any other I've used. I hope that it lasts as long or longer than others I've tried in the past.

Takes a lot if work, but it looks great.
