Hi im a trying to render some walls in my house and ive helped on a few jobs and it looks so easy (how fooled was I ) anyway ive got my mix done and the render on the wall but in some areas it seems to crack and then fall off the wall.
I have pva'd the wall but this has not helped so any help would be good. Also could I be pushing the trowl to hard against the wall i.e do you just lightly put the mix on then flatten after????????
About 6 of my neighbours had a firm do this task, but in all cases the walls were jet-washed first to remove lichen, at a cost of about Â£100. The first coat of mortar went on over metal corner-strips, and edging between semi-detached houses. The jet-wash machine was a professional unit-- petrol powered, with a large carbuoy of water in the same trailer as the pump, but I don't think grit was used.
