What is the best render for a house?
Lime plaster is a great option for those looking for a breathable house rendering system. The advantages of lime render in include: It is more flexible than cement. It is breathable so prevents problems with moisture getting trapped within the wall — a common problem where cement renders are applied to old walls.

Is rendering messy?
The mess from rendering comes down to two things – Workmanship and the system itself. For example: the render removal process may just require removing lumps of render whereas the scratching process of a scraped texture system will require removing the dust left behind, hence more mess.
