I have a whole lovely wall of 70s style varnshed wood, sauna style.
I am reluctant to pull it down as I have no idea what is lurking underneath but quite fancy painting it.
As it's varnished what's the best way to prepare the surface? Do I need to strip all the varnish off or is there an easier way in this day and age of paints for every conceivable job?
Any tips would be gratefully appreciated. :D
