Sealer for black limestone

[dpmiller]

So I've got some nice black limetone slabs that will be used as a hearth. Looking to get at least one coat of sealant on before laying, but does anyone have any recommendations for a really glossy wet-look finish?

 

Thompsons Wet Look paving seal seems like a possibility (supplier-recommended) tho in the past I'd probably have ladled on good old Klear. Any other thoughts?

 

edit: Should add, it's a riven surface, not smooth

I like LTP Mattstone, but its a matt finish and I don't recall seeing a gloss equivalent

One of the great things about this site is saying nothing if we can't contribute. At least you know you aren't missing anything you could have done knowing.

Bu here goes..Stone tiles for bathrooms get treated with a special liquid. Is it right for you? I don't know.

LTP is very good 

Two coats using a sponge 24 hours apart

thanks guys.

@nod Blackstone or Ironwax Gloss?

[PeterW]

Iron wax gloss is good but not sure how it will like the heat of the stove but if it’s only a small amount you can always redo it regularly

No

The gloss finish looks terrible
