Kilkenny Honed Limestone Sealer question - TilersForums.com

[Barnjet]

Hi Guys

Newbie here, hope you can help. I’m helping my son on his building project. He is getting his builder to install 45sqm of Kilkenny Stone Washed Light limestone tiles ( 600 x 400 x 20). The builder has laid lots of stone before and has recommended Lithofin Stain Stop MN as the sealer.

We have experimented on a scrap piece and are worried that after 2 coats, the tiles are significantly darker. I have read on this forum and elsewhere that Lithofin is neutral so have we misapplied the Lithofin on the test piece? Hopefully I have managed to insert a copy photo of the test piece. Don’t worry about the other Topps sealer on the left, we won’t be using that one.
Any advice much appreciated. Thanks in advance

IMHO Lithofin stain stop is the best but I see your issue.
Does it not lighten up after a 24hr period.

Have you tried wiping a stone with a clean damp cloth to see how it reacts.

We will try another test piece and make sure there’s no residue left on the surface. I’ll post this later. Thanks for help so far

I’d rather have it a shade of grey ( pun intended) than not sealed.

Test No 2 completed using the Lithofin and some LTP Mattstone. Photos below

And from a different angle


In all tests so far the Lithofin has been the darkest shade and left streaky marks. The LTP is less dark, and streak free but is it as good as the Lithofin?

One thing I notice is the Lithofin has a shelf life of 3 years and this tin looks like it’s been knocking around ever since Shades of Grey was written Would that cause this issue?

Thanks for advice so far.

Yes TJ
The builder definitely wants to seal before grouting and seal again. He finished laying them today and protected them. Plans to grout and seal next week
