Hi guys , I've just laid patio with imported flags I've put a slurry under each flag and S B R in the pointing . To try and keep the patio clean is it any use treating with a sealant or would it come off with foot traffic , not trying to change colour just thinking of a clear silicone that you can use on stone and brick walls , thanks
