Not sure mate, it's been spec'd in a job i've to do in a few weeks and never done it before.
Apply polymer modified basecoat, bed in alkali resistant reinforcing mesh to basecoat and mechanically fix to substrate with dowel fixings.
When i priced the job the job was explained to me through a third party months ago, fixings not mentioned. Price was accepted and work due to start in few weeks and i was emailed the spec's other day there.
I seem to remember doing a Permarock insulation job and the spread I was helping put depth pins in and called them dowel's.
