I have a circa 1880 porch ceiling composed of beadboard - getting the surfaced prepared for repainting is impossible. The homeowner has decided to settle on a smooth painted surface.
The porch is protected but exposed to weather. Some areas are 15' long. Looking for materials similar to drywall/handiboard that can be installed over existing beadboard . Then I can tape the joints and create a single large smooth surface to paint. Moldings in the feild and popcorn treatment are not acceptable. The look and cost of replacement beadboard planks (15') is out of the park. Total area circa 300 sq. foot.
