what warrior said.. thats exactly what i was taught.. always lay into itself..
thing is... skimming is laid onto a flat surface and feathering it out is easy and preferable to building up a thickness..
render (forget hardwall for the minute) is a different ballgame imo.. starting with a full trowel and feathering out onto a rough dry surface has got to be more difficult than feathering out into already laid on mix... plus laying into it your compacting it as you go... therefore stronger... feathering out render is encouraging it to fail...
maybe youd rulle back into it right to left to alleviate this?
either way, the reason i do hardwall same way is cos its the way ive always done render, and i was rendering before i was hardwalling..
i dont suppose it does matter too much with hardwall on a flatish surface...
but sharpish sand and cement on old bricks.... different ballgame??
no?
