Using old multifinish for rough filling in?

[mike42]

Hello All

I was wondering how stupid or not an idea it would be to use mix up some year old plaster I've got for large (20-40mm) gaps that are unseen or would be skimmed over afterwards? e.g. where skirting board has been removed and the plaster line needs lowering prior to new skirting being added.

If its a stupid idea, why is that - what would happen?

Should be okay. Might go off quick though so don’t knock too much up in one go!

Thanks a lot for the quick reply but arrrgghhh I forgot to mention the plaster is multi-finish (so I guess normally used for skimming)

In my book, anything would do to fill unseen holes as a base for skimming over!
