Paint the Wood
The arbor will be constructed of wood and galvanized wood-fasteners. For simplicity, paint all of the wood components for the arbor before starting construction. The simplest and quickest method for doing this is to lay the lumber pieces out as shown, and paint them all together using a paint roller. To provide good protection against the elements, we used two coats of heavy-duty latex primer followed by two coats of paint. Tip: We used untreated lumber since treated lumber has a tendency to twist and warp as it cures.
