Anyone recommend York stone flag sealant?

Moved the flags out of the garage into the kitchen extension last week. They're nicely old & pretty rough in places but cleaned up before laying. Realise they'll never match the smoothed-with-age flags in the original bit of the kitchen but need to seal the flags (and mortar) before applying a polish.

Any recommendations? Used HG products in the past but not really had the best results.

Advice appreciated.

Does it have much effect on algae or lichen growth? Particularly black-spot.

Thanks for the reply. Have you used it? Was it easy to apply? Has it worn well? Did it darken the flags?

Also interested in coverage, looks like £35 for just one litre, more than a decent scotch!

We generally use the stainstop internally on stone, doesn't change the appearance at all

I have just done 70sqm of Indian sandstone and purely based on cost I used LTP mattstone, 5L can be had for around £55. Has darkened it ever so slightly
