I'm having a cedar trellis built over my patio and am having it painted with a white, oil-based paint (to match the rest of the trim of the house).I plan on having wisteria or other vine grow up over the trellis, but my contractor told me that only a stain is recommended if foliage will be on the trellis, because the white paint will turn green, get mossy, etc. I live in Seattle so there are 9 months of very damp weather.
My question is this -- is there a way to paint the trellis white to match the rest of the house, but also water seal over the paint?
Thanks.
Mike
