Just built a doorstep over Easter and want to finish the job with some nice quarry tiles. The step finish at present is mortar and I'm unsure what to use to fix the tiles with.
What would be best bearing in mind that the surface to be tiled onto is somewhat undulating so will need to be approx 7-10mm bed?
A) An exterior floor tile adhesive and grout B) A mortar mix like I've used in the step construction
Cheers,
Dave
