You may be better with a thin coat of watered down 50/50 external grade PVA that will dry pretty well invisible, just know that it will be a whitish finish when applied. Varnish these days is pretty rubbish even so called external varieties..Can anyone please recommend a good exterior mat varnish to protect wooden G buildings to be located outside full time.
Many thanks
