The builder's sand I got from Bradfords seems quite coarse; I've used it to lay some 7N blocks, and although it doesn't feel as workable as finer sands I've used (quite a coarse surface and a few small stones) it all seems to go off OK.
Is there fundamentally a problem with using sharp sand for brick/block bonding?
Thanks
