Waterproof - Who Cares?11/22/19
With the exterior doors, we make a 7 ply panel that s just wonderful. Epoxied, with cross bands and matching grains on the veneer faces, and solid for the raises and a core of - what? Medex? Baltic Birch? Anything?
Here is my case for Anything - If water is getting into the panel/rail/stile joints, things are already going wrong as they slide downhill. MDF can only swell so much in a panel groove. We epoxy the edges on all four sides.
So....I'm looking for affirmation - "Can I get and Amen, brother!" Do others see it the way I do, or am I straying off the straight and narrow?
Im not a door builder but coming into the architectural woodworking world for the last 10 or so years from 30+ years in "the field" I am obsessive about edge sealing and pocketed/trapped water. The obsession extends to the bottom edge of a piece of home center brick mold or any exterior wood. I have yet to have any engineered wood product in my hands or my work that doesnt command the respect of, and still behave like, wood at some level.
Times change. Wood doors in my area are lusted after then poorly maintained but are usually rejected on price before it ever gets to that point. Their days here have been in thier dying gasps for a while now.
I dont even know of many high end homes in my area (which would be considered mid level in any other market) that would pay for, much less maintain, one.
Sad, but it is what it is.
Here's my take on the situation.
If it's going to be Baltic Birch, get it with the exterior glue. If it's MDF, go with Extria or Medex. You'll sleep better at night.
Yes, seal the heck out of the edges. I love epoxy for this kind of work.

Now that you have joined the Dark side if the Force...
We use Exteria as a core. Sold wood edge glued and thick venear face glued with epoxy. Nothing to rot, the epoxy will not fail. It prevents moisture absorption into the mdf. The mdf moves exponentially less than solid wood.
We embraced the Dark side decades ago. Sleeping like a baby and making money ever since.
