The pros and cons of painting wood trim
The former Modern Painting article asked a deceptively difficult question: should natural wood trim be painted? The right answer depends less on fashion than on the wood, finish, building age, desired maintenance and whether future owners may value the original material.
Reasons owners choose paint
- A cohesive room: a consistent trim colour can connect mismatched repairs and make wall colours easier to coordinate.
- Surface protection: a compatible coating can protect properly prepared wood from routine wear and moisture.
- Repair visibility: preparation exposes loose coatings, failed caulk and damaged areas that should be corrected first.
Reasons to keep a clear finish
- Character and grain: high-quality or historically significant millwork may be difficult to replace.
- Reversibility: removing paint later is labour-intensive and can damage profiles.
- Preparation burden: glossy finishes, stains, waxes and contamination can prevent adhesion unless they are identified and prepared correctly.
Before sanding an older surface
Homes built before 1978 may contain lead-based paint. Do not dry-sand or otherwise disturb a suspect coating without understanding the risk. The EPA recommends lead-safe practices and requires certified contractors for many paid renovation activities that disturb painted surfaces in pre-1978 housing.
A durable decision process
- Document the existing trim and test an inconspicuous area.
- Identify the wood, finish and any moisture or adhesion problem.
- Decide whether the aim is preservation, uniformity or repair.
- Follow the coating manufacturer's cleaning, scuffing, priming and curing instructions.
- Make a small sample board or section before committing to a full room.
