consistency

by phil

If I buy plaster in powder form, what mixture do I use? I mean, how thick or thin should it be? It's just mixed with water isn't it?

Thanks
Phil

If you go to www.diyplastering.co.uk (home) page) scroll down to the 1st video you'll see a demonstration.
When the whisk is pulled out the peak left behind should be about an 1 inch high.

 Setting time of plaster
by: Paul

Multi-finish plaster should stay workable for 40 minutes and take at least one and a half hours before setting. If it sets any quicker than this, it must be due to either dirty water or old plaster. Therefore if you are using clean tap water then try a new bag of plaster.
You do not need to add anything else.
Just make sure the suction on the wall is controlled either by damping down or through more coats of PVA as required.
