Wood vs. MDF: Which Trim Material Is Best for Your Project?

If you’re planning to paint your interior trim, the two most popular choices for smooth even paint coverage are Poplar and MDF. Many installers develop a preference for one over the other depending on their needs. Use the comparison below to help you choose the right trim for your home.

Primed MDF – Key Benefits

Consistent quality with uniform milling, smooth surfaces, and no knots or natural imperfections.
Ready to paint—arrives pre-primed for fast installation.
Highly stable and resistant to warping, twisting, and movement.
Cost-effective, making it ideal for large projects on a budget.
Low-emission and safe—Royal’s MDF is Phase 2 California compliant and formaldehyde-free.

Poplar Trim – Key Benefits
