In the next few weeks I've got a job where it will be the first time I'm using a spec which recommends pinning render mesh to the existing render. Mostly all the jobs I've done up until now have been striped right back to the brick. Using my common sense I would reckon it should be pinned while the base coat is still wet but an older plasterer who is going to be on the job reckons it will be fine next day. My problem with that is it could possibly cause the new render to come loose with vibration. Just looking for any other opinions on this.
