Sandstone floor flag sealer

lyndytes

Hello
I have sandstone floor flags in my cellar, i want to seal the flags but i don't know what with, i was looking at Thompson's sealer ( they do a water or a solvent one)or PVA mixed with water. Note: when i leave anything on the floor it seems to draw the moisture to the surface.

Thanks

You can get a special sealer for sandstone- sealer

PVA is definately no good for sealing- Pva

Errata

Are the flags laid straight on top of the earth ? If so it might be best not to seal them so they can continue to 'breathe'.
