Whether remodeling or building new, the trim around your new doors and along the baseboards is a work of art. But as the weeks roll into months, roll into years, the trim will show wear. Maintenance and durability are strongly related to the trim material used.
If you prefer painted trim, Medium Density Fiberboard (“MDF”) is commonly used because it is economical, consistent and has a nice appearance when painted. It is also harder than some commonly used woods. High-density polyurethane often has a decorative detail pattern and works in painted applications. Know that scuff marks, dirt and dust quickly appear on painted trim (especially white trim,) requiring time to keep it looking nice.
Pine (fir) and poplar are also economical and often chosen when a stained wood appearance is preferred. But know that these woods are fairly soft, meaning they can be scratched and nicked easily, which detracts from their appearance and adds to upkeep. Hard woods such as oak and maple are an excellent choice, but they are more expensive.
So, as with many things in life, trim choice is a trade-off of cost, appearance and durability.
