Good evening folks. I've been tasked by my daughter with making/fitting two window boards. Each
56" x 16". The only option is to use thin oak faced plywood. This will be well supported to front and rear with, I hope, adequate support in between. The ply is 5mm and of good quality. My intention is to very lightly hand sand this and apply three or more coats of Sadolin. Do I remember correctly that thin ply should be treated on both faces, or am I thinking of something else? Or am I losing the plot?
Also, Sadolin has been my preferred finish for years. Has technology now overtaken this? Thoughts/suggestions would be appreciated.
Many thanks, Nick.
