One Decision, Two Good Outcomes
Hardwood maintenance is a single fork: keep the brown or let it silver. Oiled annually, Ipe holds its deep chocolate tone indefinitely. Left alone, it weathers to an even, elegant silver-gray within a year — and loses nothing structurally. Both decks last 40+ years. There is no wrong answer, only a preference.
What there is not, is a third option where the deck stays brown by itself. UV breaks down surface pigments in any wood. Decide up front, tell your household, and the deck never disappoints anyone.
The Annual Oil Routine
If you choose brown: once a year, ideally spring. Sweep, wash with a mild deck cleaner, let it dry a day, then apply one thin coat of a penetrating UV-inhibiting hardwood oil with a pad or brush. Wipe off the excess — film-building finishes peel on dense wood and are the number one mistake we see.
A 400 sq ft deck takes about 30 minutes of actual application. That is the whole program. No sanding, no stripping, no sealing cycle. Skip a year and the deck starts to silver evenly; oil it again and the tone comes most of the way back.
The Silver Path Is Not Zero
Silvered decks still want a wash. Once or twice a year, soap, water, and a stiff brush keep pollen, mildew film, and leaf tannins from staining the surface — same care a composite deck needs, despite the brochures. Avoid pressure washing above 1,200 PSI or closer than 12 inches; it can fur the grain on any wood.
Check fasteners and gap debris while you wash. Dense kiln-dried hardwood moves very little, but leaves packed into gaps hold moisture against board edges. Ten minutes with a putty knife per season is cheap insurance.
Species Notes: Ipe, Cumaru, Garapa
Ipe (Janka 3,510) is the most forgiving — dense enough that neglect costs you color and nothing else, rated for marine exposure without treatment. Cumaru behaves almost identically with slightly bolder grain movement in the first season, so keep gaps consistent at install.
Garapa, the golden budget option, is softer at 1,650 and appreciates the oil more: its blond tone shifts faster in full sun. Under cover, Garapa holds color beautifully with minimal effort. Whatever the species, the boards came out of our yards kiln-dried and milled four sides — the maintenance schedule is the easy part.
