I’m almost ready to glue up a set of double doors for a remodeled plantation home (Tennessee). They’re made of 150 year old yellow poplar which was reclaimed from joists etc within the home. They’re bone dry with amazingly tight grain, and are beautiful except they’re GREEN!

Fortunately, they will receive almost zero exposure to either rain or sun, on account of being under a gargantuan porch (maybe 16’ square).

Some defects are getting epoxied, some knots are going to get drilled through and replaced with a dowel.

So – I wonder if anyone with more experience can assist me here in suggesting an appropriate finish? I’d like to avoid a film finish on account of the risk of catastrophic failure with the Southern humidity we experience, and would like to get the color to a medium brown.

The forgiving nature of the door’s placement leads me to intuit that a penetrating stain and oil in one would be a good choice here. Seasonal movement is fine as they’re double doors and the astragal can allow for it, so I feel fighting against moisture with a varnish is unnecessary.

Thanks all

I would use a dye to get the color you want and then finish the doors with blend of BLO and spar varnish and mineral spirits in equal measure. Use a quality spar varnish such as Epifanes from a marine supply. That will give you an oil blend finish that will be easily renewable without having to strip the old finish off and will be more durable than a straight oil finish.

Dyes do not hold up well exterior , noted exception to Metal Complex dyes ( man made pigments )
The only one i know of that say their dyes can be used exterior is WD Lockwood
look under water base dyes and find the Metal complex color chart , they are powder and you simply mix with water .
As for a finish, after some pretty drastic finish failure using a spar varnish , i totally agree , I dont want a film finish .
One finish I tested over a 3 year period was called One Time , its an oil finish,
It can be easily recoated and maintained ….

Just my .02

My research is leading me either to epifanes varnish mixture with stain and linseed oil, or straight up sikkens cetol. I’m leaning towards sikkens.
