Bonding any of the? olifin family of? polymers has historically been a
real crap shoot.
I've used E-Beam Rasterizing and hydrogen flame treatments to get the
oils off the first molecular layer of the? surface.?? There are paints?
today that? can get past the oily surface film? and adhere - sort of.
PSA adhesives work pretty well especially of they are heat bonded.? But?
for this application (a door)? I think I'd toss that whole episode of
This Old house in the rubbish.
Why not use an epoxy?? Not? one of those so called penetrating epoxies,
but a good one? like West or 3-m.? You can get a high build with
multiple coats and it'll stick like - - well epoxy.

This may not be news to some of you but this is the first time I have heard of this. I was watching an old This Old House episode during lunch and caught this detail of four building.
To protect the end grain of stiles this manufacturer uses a polyethylene block as part of the stile at bottom. Here are some pics from TV screen.
Isn?€?t polyethylene difficult to glue. I will look up to confirm if west system epoxy will work with polyethylene as that is what I intend to use.
Not knowing much about it, seems like a good idea. I would like to do this to the top and bottom of an exterior door I plan to build.
Any thoughts?
