Outdoor wood fails when it is asked to be two things at once: easy to mill and immune to rain. The species we put on the outdoor row are the opposite — dense, oily or naturally durable, and slower to work. That is the trade that keeps a deck or a patio table standing.
Teak is the reference: high oil content, calm movement, a surface that weathers instead of rotting. Beside it we specify other Mesoamerican hardwoods when the job wants a darker line, a harder face or a different budget. The question is always the same: sun, standing water, fasteners, and how much maintenance the client will actually do.
