Not at all familiar with "yellow board". Never heard of it. Wherever you bought it, they should be able to provide you with manufacturer's instructions, including paint prep/

Yellow board is a new one to me, too, but if it is just another variation of green board, it really isn't that much better than regular gypsum drywall. I'd apply a good primer such as Kilz then paint it just like any other drywall.

You mean paperless? If so, you'll need to skim-coat it before you do anything, otherwise the texture of the fiberglass fibers shows through. Use setting compound (powder, in a bag), not premix (in a bucket) - premix goes soft everytime it gets damp.

If it says it's paintable, then paint it. 
I would use a tinted primer, then 2 coats of your finish color. I use Sherwin-Williams paint, because the shop is close to my house, they can do color matching and tinting, and there are usually no lines. Unlike HD/Lowe's.
Out of curiosity, what brand name/manufacturer is this yellow board?

It does have fierglass fibers in it - I noticed as I made cuts. I know I have some in my arms because when I rest my arms on a flat surface I feel the prickly thorns but they are so small I can't see them to pull them out...
I don't think it is paperless so the texture should be fine - but I'll do more googles to be on the safe side.

BJ - brand and product name? Seems like none of us have heard of this stuff.

Sounds like DensGlass...
You can paint it, but are advised to skim coat it first...

I have been hearing about papeless drywall. The idea being that mold forms and feeds on the paper, not the gypsum. I have not seen it yet, but was not under the impression that it was in any way moisture resistant, any more than greenboard ever was. Just helps avoid a mold disaster.
Sounds like there are some new materials on the market, and I need to go out and "get smart" about their usage.

rigid sponge.
"moisture resistant" means it hold up better than regular drywall under the effect of moisture. That is what greenboard is and was. Able to resist the effect of h20. Not fall to pieces.
Mold feeds on organic matter. If yellow board has no paper, that much is better than greenboard. BUT that still won't make it a good base product for a tiled tub-shower surround, because shower water has organic matter in it too. Resistant board will suck some of that water up and feed mold with it. Not ideal. Not pretty. Not good for your health in the long term.

Some of the guys at JLC have been testing this stuff, sticking it in a bucket of water for a week & apparently it doesn't even go soft. Dry it out, you can't tell it was ever wet.
Another guy had a basement get flooded, during those big floods in Jersey this year, and it survived just fine.
On the other hand, it's a b*tch to work with, because of the fiberglass fibers; and having to skim it adds a fair bit of labor to the install.
Still not sure that's what BJ means by yellow board, though: he said it wasn't paperless...?? Hope he gets back to us.

personally i am so glad there is now a paperless sheetrock, since I can smell paper rotting from afar. The paper rotting under paint and a skim coat of compound just makes most households smell like they doo. Exceot those built before WW2 and a few rococo mansions with CBU walls plastered over. (BTW, mold = rot.)

I used the yellow board in most of the bathroom too. I know it is has fiberglass when I carried it with bare arms. Wish there had been a warning on it. Anyway, I couldn't pick the fibers off but they came off with a loufah type bath "puff". I was scratched for a few days, but learned to wear long sleeves when working with that stuff.
