I have laid some natural limestone floor tiles, very pale, porous and open grained. I haven't grouted yet and I am thinking I should treat them with something before I drag coloured grout across them, which is the recommended procedure. I left topps tiles without buying their sealant already shocked at the price of all the 'extras' . I wondered if I might use something cheaper, since this is only a little patch of stone floor in an outbuilding and not an area of heave wear.
So what is a stone sealer? like a varnish? synthetic? oil? PVA? Acrylic? wax? What would enhance the appearance of my limestone and make it easier to clean? preventing the grout from staining it while allowing the grout to stick itself in the joins?
