We had thus house newly rendered 10 years ago with traditional sand and cement render. Since then the front of it which is North facing so therefore doesn't get a lot of sun has needed yearly painting. Mostly we don't get it painted yearly and the side and back could last two years or more. The front looks horrendous, loads of flaking patches. The last time it only took 6 months before the front was peeling off.
Someone must have a solution to this. I've just had another 1k quote to get it painted again, not including the paint or primer.
