Despite careful preparation and sticking to the "rules" my stone slabs, bedded on 50mm of 7:1 sand cement mix, have not "stuck" down. They can mostly be lifted. Fortunately they are bedded on a continuous pad of cement so they don't rock and remain nicely level. My question is: should I rely on the pointing in the cracks to lock them in place or should I think about an adhesive on the undersurface?
Thanks for any thoughts
