Thanks for this information. Its a job Paul Clamp (remember him?) has passed my way. The job is in Harrogate so 60 mile plus away from me and I am working out of a Mini Countryman boot atm hence labour only.
I am passing Harrogate on my way to a job in Scotland so maybe tape on the way there and bead up, base coat on the way back.
But this customer was looking for it being taped up for painting, can it be taped on the way up and a tight skim over on the way back like you would in dry lining? Thinking of being on my own and the thin coat will need lots of covering up and that could be two trips.
This is if they decide to accept the facts that it is boarded wrong!
Not spoken to Clampy for a few years... he still at Gr33n?
yeah - tape and joint on way up... the taoe and joint application sits on the surface is the board... NOT Like a tapered plaster board... It will look like a chess board if just painted!
as a minimum, would recommend a 5mm basecoat and mesh layer to the t&j’d boards, this gives a weathertight finish, then paint if they don’t want a textured finish
im sure a man of your experience knows not to over work a basecoat, it usually brings the grits to the surface... just apply, let pull a bit, then flatted and leave
