Half the exterior calls we take in Muskoka start with this question. The short answer: paint forms a film on top of wood; stain penetrates into it. Which one your cottage needs depends on what the wood is, what's on it now, and how it's exposed, get it wrong and you buy the peel-scrape-recoat cycle for life.
When is stain the right choice?
- Log homes: always stain, never paint. Logs move and breathe; a paint film traps moisture and peels in sheets. Penetrating stains restore colour while letting the wood release moisture.
- Cedar siding and shingles: cedar's natural oils resist film adhesion. Semi-transparent stains show the grain and weather gracefully instead of peeling.
- Decks, docks, and horizontal wood: film finishes fail fast under foot traffic, snow load, and standing water. Penetrating stain is the only system that ages well flat.
- New or newly stripped wood: the one moment you can choose any system. Stain keeps future maintenance simple: clean and recoat, no scraping.
When is paint the right choice?
- Previously painted surfaces in good shape: staying with a quality exterior paint over sound existing paint is usually smarter than a full chemical strip.
- Smooth clapboard and trim where you want crisp, opaque colour, classic white-trim cottage looks are a paint system.
- Fibre cement, aluminum, and previously coated brick or stucco, these are paint surfaces by design.
- Maximum colour choice: paint offers full opacity and any colour; solid stain sits in between, opaque like paint but breathing more on wood.
How long does each last on the water?
On lakeside exposure with proper prep: quality exterior paint typically runs 7–10 years on siding; solid stain 5–8; semi-transparent stain 3–5 with an easy clean-and-recoat (no scraping) when it fades. South- and west-facing walls above water weather fastest everywhere, UV off the lake nearly doubles exposure. The maintenance personality matters as much as the number: stain fades gracefully, paint fails visibly.
Common questions
Can you paint over stain, or stain over paint?
Paint over solid stain works with proper cleaning and priming. Going the other way, penetrating stain over paint, requires stripping to bare wood, which is real work but breaks the peeling cycle permanently.
What's the difference between solid and semi-transparent stain?
Solid stain is opaque like paint but formulated to breathe on wood; semi-transparent shows grain and colour together. Older, patched wood usually wants solid; newer cedar looks best semi-transparent.
My cottage has peeling paint on cedar: what now?
That's the classic wrong-system symptom. The honest fix is removing the failing film where it's loose, priming with a bonding primer, and continuing with paint, or a full strip back to bare cedar to convert to stain. We'll price both honestly.
Do boathouses need different products?
The waterline zone does: constant humidity and spray call for marine-appropriate finishes low on the structure, with standard exterior systems above. It's a detail city painters miss.
