While I would not set tile over MDF I was considering using it as trim in a bathroom. I heard dire warnings about not using it as baseboard because of potential water damage. I took a piece of the MDF trim with unfinished edges and submerged it underwater for several hours, when I removed it it dried rapidly and no ill effect from the water. It didn't appear to have absorbed any water. Just wonder if any of you use MDF trim? John.

I use it all the time--it is super cheap, holds paint well, is a bear to install alone, and doen't wear well, with nicks and dings. If you chose to use it, prime the bejesus out of it, front and back, and put two coats of a good quality paint on it.

It will ding and dent very easily, so if that bothers you, stay clear.

I will say that most of my work is not paint grade, but stain grade, so MDF is out of the question.

I wouldn't use MDF, it might take some time but eventually it will start to go all furry and fall to bits. I see a lot of MDF trim in bathrooms that is knackered - timber lasts much better.
