I am planning a project made out of MDO, and I was wondering if anything needed to be done to the edges before painting it. Do they need to be sealed or filled? If they need to be filled what should I use? For MDF I’ve used joint compound to fill the edges, would that work for MDO as well?

Thanks for any advice you have.

I would use iron-on edge banding…..I use it all the time to edge band all my plywood, MDF or MDO….You can get it at Home Depot or Lowes….It had glue on the back side, and you just take an old iron and iron it on, run a block of wood over it to press it down good, and trim the edges…..easy peasy, nice and easy…..You’re ready to paint….Try to use edge filler is too messy and too much trouble…this is quicker and better…...

If you’re using MDO, I guess it’s for an exterior project.
I’d use Bondo

They should be filled if your concerned with appearance (Bondo would probably be my choice as well) but if you’re worried about it’s durability it will still old together with just the paint on the edge. Be sure to give it a good covering. It is made for outdoor signs.
