so why did you use sand and cement as a scratch coat and then lime render. you shoot people down and then say you did that. I personally don't care how you do things, Like Steve said, he has been around a long time and I only met him about 3 years ago at Lord and Downings but sense then I have heard nothing but good about his workmanship. I have also been plastering and still am for over 25 years and spent my time with my father who used to do all lime work but neither of us constantly post vids of our lastest jobs or boost about where are last job was. and to answer another question you keep asking, no I'm not a saleman, I'm a spread.
Back to the question, if your an expert in lime renders why did you use a cement scratch. I presume you used lime so the block or brickwork can breath, as you well know, lime render helps the building dry out after a very wet spell as it does not retain the water in the blocks or bricks, if your an expert like you claim you will know that putting a cement and sand scratch coat behind the lime render will have the reverse as cement renders will not let the drying out period as fast and as well as lime would, this will in time cause trapped water to be drawn to the internal walls of the building. You did say that the reason you used lime on that farmhouse and not mono was because it was single skin brick so by putting the sand and cement render on first you are going to create all sorts of damp problems.
