I have a couple of jobs coming up with thermalite/celcon blocks that are to be float rendered and set. Trouble is, it's very unusual to come across these blocks in Australia.
we normally work on a fastwall maxi brick(clay pot type block). English brickies like to use them here(they are used to laying them and prefer them). I know in the UK you have materials that can cover them, however we don't have your wonderful thistle/bg etc stuff. we just have basic lime/cement/sand for render(float) and lime putty/hardwall for skim(white set). I have done a little external sand finish render on thermalites a couple of years back but it cracked to buggery. any advice is appreciated.
