Best value: MDF Primed at $231.43MDF primed casing is the most affordable and takes paint smoothly. Pine is a classic choice for staining or painting. Oak provides a premium hardwood appearance ideal for stain-grade trim. PVC casing is moisture-proof and rot-resistant, perfect for bathrooms and exterior-facing trim.
