The paintwork of the front door and door frame keeps getting damaged
due to carelessness on the part of residents. Is there a more durable
paint we could use or does the nature of wood mean that any paint is
liable to impact damage?

The "residents" who have caused me problems in the past have been my
dogs. When I just filled and repainted my rather nice living room door I
seriously thought about putting a sheet of polycarbonate over the
vulnerable area. I didn't in the end because the current residents are
better behaved.

The short answer is that the underlying wood is likely to deform and no
paint will solve that although (for example) two pack epoxies are tougher.

Is it also exposed to the sun and the cold?
I have found the paint tends to go brittle and crack or chip. I'm sure old
fashioned paint was not so bad.

Sun occasionally. Cold yes. Coronaviruis maybe. It was only painted
about two months ago. One of my neighbours has one of these big silly
prams but of course I cannot prove anything.

At the moment, I am looking for a technological solution. I see that
Network Rail used flake glass epoxy on the Forth Bridge but I believe
this is wholly unsuitable.

A good epoxy on bare wood can't be beaten. That's why boats use it.

Unless I'm mistaken, using that on a timber door exterior traps migrating damp leading to rot.

The trick is to make sure its dry before you coat it.

Properly coated the door won't be allowing any damp in.

I'll admit I've had problems on my boat - but they are the areas where
the damp cover sat on it (should have bought a new one sooner). The damp
has not migrated into the rest of it, and once I'd replaced an inch or
so of timber along the gunwhale the rest of it is solid.

Including the bits I jump up and down on. Which is likely to be harder
work than a door would get.

That sounds like a good reason not to use alkyd, and to use epoxy instead.

Really. No exterior wooden door has paint that remains gap & crack free. Paint that won't let migrating damp out causes rot. There is akso the separate question of flexibility & seasonal movement.

Even better with a polyurethane topcoat to protect it from UV. As used
on Nuclear Fuel transport flasks.

Epoxy is prone to UV damage. I can't recall what the varnish on mine is.

Trouble I had is that once it had had a few bangs, then sat with a wet
canvas cover on it, the result was local damage.
