I have a chalet which I have Part Roughcasted myself but as the ready made material to do this is so costly I decided to try and mix the next batch myself - - I was told that to do this I would need to Mix Rendabond with water and a handful of sand to make a slurry then paint on with a roller -- as I have never done anything like this before could anyone tell me what ratio of each IE: Rendabond and water I would need?
