I’m about to finish trimming out my living room which is of fairly decent size. For the door and window casing, I’ve used a paint grade pre-primed colonial moulding. I plan on framing and trimming out the rest of the room with crown and a wainscoting. For the crown, my wife is pushing me for dental crown…even though painting it will be a major pain (don’t own a sprayer.)
I have really irregular ceilings and walls. Not flat at all. Should I stick with the pine? I was think I might want to go with the MDF since it’s slight flexible and would follow the contours of ceiling and walls. Is that thinking flawed?
I was also thinking the MDF would be more stable throughout the seasonal changes. I’ve had some gaps appear in the rest of the house where I have used paint grade pine; I simply filled in with caulk and touched up the paint in those spots.
One more question, what do you use to glue an MDF scarf joint? I tried to standard Elmers wood glue once but it simply just absorbed into the cut.
Thanks in advance for your help.
