Clay and lime plaster test

We are doing a plaster test of both clay plaster and lime plaster onto the magnesium board.  This is the clay test in the downstairs WC.  The plaster is made by Clayworks and the colour is 'buff'.  It is still drying out in this photo so it will get a bit lighter.  The stripes show the uneven drying out where the gypsum plaster is underneath.

The second test we did was lime plaster on the ceiling in bedroom 4.  The plaster was 3/2 lime plaster by Mike Wye.

Both tests were quite successful.  None of the joints cracked.  There was a tiny area of cracking on the ceiling which we believe was down to the plaster being slightly too thick in this place.  To overcome this in the future we are going to flatten off any areas of magnesium board which get rucked up where the fixings have gone in and try and get the gypsum plaster over the board joints even flatter.  These two things determine the minimum thickness of the finished plaster.

More preparation to the joints between magnesium board

After taping the joints with scrim tape they  need a thin coat of gypsum over the tape.

This needs to be as flat as possible and can be smoothed off with water while being applied.

The downstairs loo.

After the gypsum has been applied the DG27 primer needs to be applied over the whole surface.  The DG27 not only provides a key for the plaster but helps control the suction of the boards - preventing the moisture being taken out of the plaster too quickly.
