How to plaster new wall

[G1nzo]

Had a shower room installed downstairs
Wall was made of wooden studs with Plasterboard
Inside tiling is complete but i need to Plaster the outside
I dont want a perfectly smooth finish as it an old Farmhouse and theres not a straight flat wall in the house ...
So what need to go onto the plasterboard what kind of plaster
and how many Coats
The wall be just be enulsioned when finished
there are a few joints where the plasterboard sheets meet
to these need anything special done to them before plastering ?
about 12 ft x 8 ft less a door
skirting board is removed and door trim can be removed

Thanks in advance

G1,
Before you plaster your new wall,all joints in the plasterboard will need to be taped with self adhesive joint scrim tape.You can use Thistle Multi Finish to plaster the wall with,and you would need 2 coats minimum for this. Another way is to coat the wall with Bonding Coat plaster and then finish with the 2 coats of Multi Finish. ONE 25kg bag of Multi Finish would be enough for your job,and if you went for the Bonding Coat/Multi Finish option, ONE 25kg bag of Bonding Coat would do as well.A roll of joint scrim tape is available in most DIY stores.As regards to the finish of your wall,rough/smooth etc,that would be up to you.

No Pva on the Plasterboard 1st
Or plaster straight onto the Plasterboard ??

Do not pva just plaster straight onto board

scrim the gaps between the plaster boards. No pva required. Use "One coat" to skim on. Two coats are advisable. I am sure the finish is not a priority for you as it seems preferable to have a rough uneven finish.

An idea you might want to experiment with on a loose piece of board first, just to see if you like the result;

Mix 50% pva unibond and water, add a hand full of builders sharp sand, and some one coat plaster. Mix to a heavy syrup consistency. Paint on to the newly plasters board, but make sure the plaster has completly dried first. Then paint on with a heavy duty masonry brush. Really slap it on. Use random strokes so that it looks rough a rustic.

When this has dried completely yo can paint it with what ever paint you want.
I would upva it first though just to make sure the surface is clean free from loose sand.


Good luck!
