I'm thinking of having vinyl floor tiles in my kitchen and conservatory but I cannot afford amtico or karndean etc. I've found some cheaper slate effect tiles that I like but I think they would look more authentic if the was a "grout line" between the tiles rather than butted up together. Amtico sell strips to give a grout affect but does anyone know if there is another way of achieving this affect? Would it be possible to use any type of flexible grout? thanks for any ideas.
