You can but you will have a problem making it stick and not crack. I usually use hard tack or chicken wire stapled to the plywood so that the plaster has something to stick onto.

Plaster On Wood

Apply straight to the plaster in a non wet area only. Any area classified as a "wet" area such as in a shower or tub area, you must put up a cement based backer board or pull the plaster board out and recess the cement backer board in, having it come flush with the plaster. This will depend on what type of trim is available for your tile. Then a cement based mortar is used to adhere the tile to it. In the non wet area thin set or a mastic can be used, the plastic must be primed or painted to bond to. Any questions you can e mail me through my avatar and check my qualifications there. GL

dilute pva with 5 parts water, paint this on then apply dabs of bonding compound, press plasterboard into position, scrim all joints, then apply two coats of finish plaster. alternately you could paint or wallpaper the ply wood which would save you time money and mess.

one other possible way is if you have the room is to put the thinnest sheet of plaster board onto the plyboard first and then skim this, but prior to the skimming you should use a pva adeshive on the wood and then dot and dab the boards so you don't have to use nails, good luck

PLASPRIME leave to dry,

Yes--You really just have to rough up the wood and then the plaster will adhere. I did this at my lake house. You can either sand it or use a product called Strip Ease. You will probably have to do 2 layers.

How big of an area? Anything over 10" is going to crack. if it's a small repair- just take your time layering it and let it dry completely and then do another layer.

cover the ply with plasterboard (9.5mm or 12.5mm), then skim it. DONT skim the ply wood cause it wont work, it will go off straight away (even if you pva it first), it will crack and it wont look good

NO! You must seal it first with a primer. It will discolor and crack right away. I do faux finishes and it coesn't hold up nice at all. Just use a cheap primer. good luck
