I'm fitting a smaller door in my porch and making up the 8 inches either side in studwork. Instead of using eml or riblath I'm thinking of using something like aqua panel on the outside. Screwing to timber and hammer fix over existing render. That way I've only one backing to render on. Plan is aqua Panel and maybe rend aid bed some mesh in then top with ocr. I'm a bid old school but I'm fed up with cracks using riblath.
What people think. does rendaid stick to cement boards
