Sorry for being a bit vauge (I am new) my job is a terrace in spain, on three sides of the house, the reasons for replacing, there are four different size and shades as all were done at different times, and the edge is bricked and I want to take the tiles right up to the edge, with an edging tile. The exsisting tiles are are sound and firm, my question boils down to what adhisive would be suitable for sticking to the existing tiles. I'd be greatfull for any advice.
Ken.
