Glue after primer ?

[Heated 66]

Hi Folks
I'm restoring a heritage building and have some pine and cedar boards that have a pronounced grain curve. Should you keep the ends of (crown) Arch curve against the structure when fastening ?
Also I'd like to pre-assemble the window trim and fasten the decorative chair rail to the trim before instalation can I prime first then assemble with glue and nails? The or is it better to use glue and fastener and then prime and paint.
Basically sealing all wood on all 6 sides
Exterior glues poly or white glue.


Pre assembly indoors speeds up final installation

He is Canadian, not a Yank, quite different really. Also their weather can get a lot colder than ours, and we have a lot less timber cladding than they do. My Parents lived in the middle of canada some years ago, the letterbox bolts would get icicles on the inside in the winter. Also building code insisted on two heating units per property on the grounds that a single boiler failing could easily be fatal in winter. Also, it was too cold to salt the roads, it would not melt the snow.
