Hello,
What advice do you give me for this triple layer oak jamb- 4cm thickness, 4 years old, given with semi-waxed varnish (water based)? It withstood well over 3 winters, completely exposed to hard weather conditions. Would it be better clean the oak and to treat it with some special oil for exterior and hard weather conditions, just to penetrate it an no more?
Thanks a lot, Nicholas
