Title: Plastering question
Post by Demelza100 on Sep 7^th, 2009, 7:29pm

Can anyone tell me if you can plaster on to ply? I have boarded
most of the kitchen walls as I was advised this was the best thing
to do as it was better for hanging units. I don't want tiles above or below the wall units and was going to have them plastered and then
painted. However, yesterday, when the work was done someone told me you cannot skim onto wood. I have asked a plasterer who also says he has never heard of it. Can anyone give any advice on this eg can I skim if I use some sort of sealer first? Can I use a metal mesh?or is there a wide tape like they use for plastering on board?
Any advice welcome. :-?

The best option is to cover the ply with plasterboard and then plaster the plasterboard. Ply moves slightly with changes in moisture and is likely to crack any plaster applied to it even if it is covered with a metal mesh.

Hi, as the previous comment notes you need to board the room correctly with plasterboard in order to plaster. Should this be a difficult task, your only viable alternative is to line the room. Buy trade quality 1200 grade lining paper, ensure the imperfections between the ply boards are feathered, (blended) in with powder based filler so as not to show imperfection underneath the lining paper once erected, rub the filler down with 120 grade sandpaper. Then hang the lining paper HORIZONTILLY not vertically. This drastically reduces the advent of visible seams and when painted (if carried out well) will look almost exactly like plastered walls . Hope this helps
