Anybody using Extira for outdoor work?

Hi Neil
Looks similar to Medex exterior MDF.
Have been using that for quite some time, and it is moisture resistant NOT waterproof.
Used to use the Dulux Weathershield solvent based paint system with it very succesfully.
However since the demise of the solvents in favour of waterbased am still experimenting.
Medex is available from most timber merchants in variety of size… and some builders merchants.
MDF safety precautions required for machining
Hope this is of some use and not clouding the issue 😳

I wonder is it what the Americans call MDO, used some of that over there and loved working with it. It was being used outdoors and far as I know it is still performing. That was in Texas mind you, which has a subtly different climate to here! 🙂
Would love to be able to get it over here.

Extira is not MDO. (Mdo is plywood with a paper coating)
Extira like a solid brick of layered fiber.
You can use it for exterior jobs.
It’s simply just SO heavy, and it’s hard to get it to take a coat of paint well due to its surface being treated with something to keep it from rotting.
It works, it’s just not for me.
I guess it would be OK to apply a print to.
But you have to be pretty strong to just lift it.
(I don’t use MDO, either)
The older I get the more I like to use aluminum composite.
Love….Jill

Thanks folks. Maybe not all that it’s cracked up to be, but you never know. If anybody knows of a supplier in the UK I’d be interested to speak to them all the same. Wouldn’t mind getting my hands on a sample.

Extira used to send free samples.
