MDF in the long term.

[Primarch]

In recent years MDF has become the terrain material of choice thanks to the likes of 4ground and Sarissa. I have MDF bases on minis and some movement trays made of the stuff too.

I have been giving some thought to how survivable MDF is in the long run. Japan can be a pretty humid place, which can lead to issues of rotting and warping in natural materials. I am considering going back over all of my terrain and making sure every square milometre is painted.

What do you think? A worthwhile endeavor, or am I just worrying over nothing?

I'd think just giving it a nice thick coat of clear varnish (which you could then cover over with matte, of course) would do the trick - that said, I have some pieces of terrain I mounted up on regular corrugated cardboard like 15 years ago which still look fine. You do read about MDF being less water-resistant than plywood, but my impression is that's mostly talking about situations where it's basically sitting in standing water, or in a damp basement or what have you.
