MDF vs Pine base molding (subfloor, vinyl, vacuum cleaner, paint)

[Parsec]

I am re-doing the floors in my mudroom and will be replacing the 80's style base molding with something more modern. The mudroom is in the basement which is 75% below-grade except for the garage side. I've chosen vinyl plank flooring due to moisture concerns. I am in Eastern Massachusetts. Would you choose MDF or pine base molding to complete the job? I'm not sure what the difference is, although the price is about the same (about $10 extra for pine to do the whole room).

Whoa, we are twins. re-doing my basement and am finished with subfloor. 75% below grade and awaiting my vinyl plank flooring to be delivered. finishing my drywall this weekend.

I used MDF for crown mold and will likely do so for base.

MDF is like a sponge when water is within reach.

For your project I'd spec pine- Mdf is OK for a bedroom, that's about it.

Not MDF. MDF has a magical power to reach out and find water so as to commit suicide.
Personally, I prefer poplar for its paint holding properties. And, it is much harder than pine.

Basement? Poly is the only thing I would use. Seriously, for applications where moisture is a potential issue it the superior choice -- ProFinsih

Seconded. Actually, I try to use the plastic molding throughout the house -- you don't need to paint it, it doesn't scuff when the vacuum cleaner bangs into it and you just have to wipe it occasionally with a damp rag to clean it off. But I always go with the practical over the "elegant" in my decorating choices.
