Junebug - Miracle 511 is one of the better sealers on the market - and I've used it on the granite and marble in the homes I've lived in. There are numerous reviews on GW regarding it so you can easily search for those.

I would definitely not strip it off, but would make sure that water beads on the surface of the counters. If it doesn't, it could likely use another coat or two of the same sealer.

Also remember, sealers don't last forever and depending on type of stone and frequency of use, will need to be resealed periodically. Luckily it's an easy process for the homeowner to do, and I'd also recommend doing it with Miracle 511.

And here's to hoping you really do have SW Quartizite - Most Super Whites are really a dolomitic marble and while they may be more resistant to staining with a sealer, no sealer on the market will protect from "etching".

Thanks kjo_tx. Very helpful. and yes, I hope we have the real thing too!

I use the miracle 511 porous plus on my Carrara. Three coats and nothing is sinking into that slab! No stains anything. I have many etches but don't care. Fingers crossed your SW is a quartzite for you tho and remains etch free.

I am assuming 511 porous plus cannot be used on top of 511 Tile, Stone and Grout cleaner--correct? Should I just apply additional layers of the same sealer the fabricator used? I would rather be safe than sorry,..

Would love to know what you did and how it held up. What sealant did you and do you use?
