The north side of my house has quite a few spots that need repainting. But overall, it looks pretty good. I really don't want to take every inch of clapboard down to bare wood. This is my plan: - Scrape and wire brush off only areas with loose or peeling paint. - Sand entire surface enough so new paint adheres. - Wash entire surface with anti mildew spray and rinse well. - Repair any cracks and broken clapboards. - Spot prime the scraped and repaired sections. - Any clapboard with primer gets top coated entirely. Does this seem reasonably promising? Thank you very much.
