Depends on the substrate lad.on new build I mesh stress area's,on renovation jobs ,eg dodgy bricks,stonework I will use it for sure.although I will offer it to who ever is paying and give them the choice with the the cost difference.a couple quid a m2 will make a difference if tendering with others not using.
I use 10mm beads dabbed on giving about a 12mm coat in 2 passes.will possibly slump/crack if put on in one go.
