Confession time ... several years ago I laid a 40 sq.m. patio using
600x600 slabs and thought it would be a good idea to fill the 12mm gaps with pea shingle rather than mortar. History has shown the pea shingle to be a bad idea so I've finally decided to point the slabs with mortar.What's the best/fastest pointing method? There seem to be two types of manual mortar guns, one type is like a mastic gun (with either metal or plastic nozzles) the other is just a plunger in a tube - are they any good?
Seems to be a debate about sharp or soft sand - advice?
