Preparing the magnesium board before plastering (clay/ lime) involves taping the joints between the boards, securing the tape by putting a thin coat of Gypsum plaster over them. To get this really smooth and flat we found the best way was to mix up the gypsum so it was quite wet and paint it over the tape.
The next step is to prime the whole lot. Generally we are using DG27 which is a gritty primer. This controls the suction of the boards and provides a key for the plaster. We have started preparing some of the boards, so hopefully some can start to be plastered while we are still finishing boarding in other areas.
