Restoring wood ceiling

A good buddy of mine commissioned me to restore his grandparents' old wood house. It has a rough wood ceiling, never been treated. It's incredibly dry, and in some areas, it's actually starting to turn to dust. I don't specialize in old wood, but I'm considering to apply a coat of linseed oil to help rejuvenate it. After that cures for a few days, I'd then apply a clear coat of the urethane resin varnish I've successfully used on other projects. Has anyone tackled a similar situation with old, dry wood? Any insights or advice would be greatly appreciated!
 
Tough job, Linseed oil is a solid choice to bring dry, dusty wood back to life, just make sure as hell its clean first and let the oil soak in real good. After its cured, your urethane varnish should just work fine for protection. Definitely test a small spot first since old wood can be a bit fragile

It's not an impossible job, but it can be if the wood's condition is terrible. In that case, there's not kind of oil on this planet that's going to save it. @Cy51.PX inspect the wood first and if it's in a bad condition, don't bother trying to get it back to its former glory.

The big Problem with linseed oil is that raw linseed oil takes a very long time to cure. yeah, we're talking weeks or even months.
If you apply a urethane varnish over it before it's fully cured, you'll end up with a finish that never properly hardens, remains tacky, and can even peel or crack
