plastering and rendering on wood

Question

I'm just wondering if you can plaster and render over wood. I have an exposed wooden lintel above a window that needs rendering on and wood around an open plan doorway that's been removed that would ideally be plastered on. 

What would i need to plaster. render on the 2 areas? Is there something i can put over so the plaster/render with attach to?

Thanks,

You can either put expanded metal lathing on it or if it’s internal & being plastered!! Plasterboard it & render into it make sure to scrim joints before skimming.

My advicebwould be screw or nail some wire mesh over the wooden lintel or chicken wire then you can apply a scratch coat of sand and cement render , then a top finish coat , that’s the only way you can apply anything without it cracking , thanks Neil poulston

Hi sorry no you can't render on wood you need to go back to block or brick on internal work then board or float and set base coat and multi finish

Hi you can use EML /Expanding metal larvae use galvanised nails you can get it in sheets or on a role depending on how much you need but wear gloves as it is really sharp and use tin snips to cut it the nails should be placed about 350/400 mm apart hope this helps

Hello.. you can’t render or plaster direct on to the wood, you would need to wire mesh over the area. And then render it

Can’t plaster over wood you would need to fix a board to it

Stephen · Answer

You can as long as you mesh the whole wooded area I sometimes use an angle bead I hammer it flat and make sure you screw or nail down firmly then plaster

Sean · Answer

Because wood will swell and shrink slightly it is not a good idea to plaster or render directly 
best to board over with plasterboard or cement board first

Hi ,yes cover the wooden areas in expanded  metal mesh then simply render, and skim over or plasterboard  the wood, render to that then scrim the joints and skim.

Neil · Answer

You can put a metal mesh over the wood to render over which would aid in the render to stick to.
To plaster over wood you would need to plasterboard over the wood or again use a metal mesh and bond then skim that area.
