Prepairing Wall for plasterer

[ScottishGasMan]

Hey all,

Fitted celotex insulation in a stud wall bolted on to existing wall, and putting up plasterboard over it in preperation for plasterer doing full room.

Not the best at cutting plasterboard, so few little gaps here and there, I know he will tape the joints before plastering, but is it worth my time using a caulk inbetween any joins that are over a few mm?

There is no need to fill minor gaps in butted up board edges.
If the gap is a little large, you can double tape the joint, which will help.
Any large holes or gaps, I would fill with bonding compound.

The other area to consider prior to applying finish plaster, is to apply thin coat beads to external jointed angles, generally on window reveals.
Once the bead is cut to size, I cut a 45 degree in the bead, where beads are going to meet each other. I also squeeze the bead in slightly, prior to fitting it, this will help prevent the bead sitting proud of the board/plaster coat.

On standard plasterboards, there is no need to prime the board prior to applying your coats of finish (two coats of plaster is the preferred and is the best method). You can use either board finish or multi-finish, multi-finish will give you a little more working time with the mix.
