This is probably a very stupid question, I’m sorry if it is but I thought I would ask as there might be someone here who knows, it is Mumsnet 
I have a lovely kitchen table that is too big for our kitchen, but it would be an absolutely lovely size for the garden. It’s wood, maybe oak.
Is there any way I could ‘treat’ or paint the table so that we could use it as an outside table?
Its a good solid table and if I sell it second hand I will just get a small amount for it, and I really need a table this size for the garden. It would be great if I could do this as I would be so happy to keep it.
Is such a thing possible?
