We are fairly close to our house being finished. The plaster used on our use is the British Multifinish gypsum.
Now I know that 99% of houses in WA use Whiteset and the advice is to seal it with an oil based sealant but everything I have read for the Multifinish says to use a "mist coat" which is acrylic paint mixed with water so the paint penetrates into the gypsum as this plaster just sucks up moisture.
Just want others opinions as in Australia I dont think anyone does this, not sure if its because this product is not widely used here or its conditions based ?
