At a recent project we were contracted to complete some interior exterior painting works. As time goes on building crack due to movement/settlement. Most painting companies will complete a quick and cheap methods of hiding the cracks prior to painting (if anything).
Whereas we prefer to bring in our rendering team and complete the best available repairs. Which usually encompasses removing all loose and drummy render, follow by several coats of strong patches and renders over days.
In one of the photos you will see a covered in orange, this is a wall that the clients decided to render entirely, the mesh we have applied prior to rendering will help to discourage cracking in the future.
