Ok..so the tiles are in and the sealer on. the tiles are quite uneven due to varying tile depths and the actual natural slate texture. They will be a nightmare to clean I think but that will be up to the mrs as she chose them. Anyway. I could do with some advice if possible about the best way to get the grout onto the tiles then cleaned up to give me the best possible look .... I am using mapei grey flexible grout and a PVC BAL grout float. Im just off out to buy a sponge and a couple of new buckets....
