I really have been putting off the repairs too long. There are several boards that have had dry rot set in. One deck board is right next to the usual route of travel, much more rot and it will become a safety hazard.
After the repairs a full coat of paint is in order. That is going to be a major job. the latticework of the shaded area will require power-washing. Repainting all of those detailed bits will also require a lot of work. I do have an air compressor, perhaps a spray rig is the right way to go.
I have a quart of exterior white paint to try out. The first item painted will be the first replaced board. I need to see how the paint looks beside the older trim paint used around the entire house. I long ago learned just how many variations of white exist in paint.
It will be a lengthy chore to complete the entire lanai. It is something I can do in stages, a few hours here, a few hours there, it will get done.
