urgent - finish to apply over paint?

[miles_hot]

Hi all

I have just done a little project with the children where they have sponged washable paint (which will apparently not come out from porous surfaces like wood which is good) over an unfinished wooden bowl. I want to seal in the paint and give a slightly smoother finish to it. I was expecting to be able to use something like Chestnut Hard Wax oil however reading the tin it says to only use on unsealed wood.

Can I still use the Oil or will it get annoyed with the water based paint finish? If not what can I use?

Many thanks

Miles
PS this is urgent as I need an answer before we go back into the garage tomorrow to finish off the present for their Mother Due to the urgency I'm cross posting to the turning, general and finishing boards so I apologise in advance

yes you can apply wax over water based paint. But it has risk to the wax to resolve some of your water based paint.
It is better if you apply a thin coat of clear coat on your paint, You can apply a thin shellac, lacquer or varnish to seal and protect your paint.

Good luck
