We just built a kitchen addition and by the time the contractor completed the exterior cedar shingles it was already late fall and too cold to paint them. They need to be painted white to match the rest of our house. They sat (along with the pine trim and everything else)untouched and unprotected over the whole winter. A painter who recently saw them here told us that we would have trouble with stain leaching through the paint coats unless we got a very good paint job. He told us that once the stain comes to the surface as it did over the winter it is very hard to cover. Unfortunately we have found that our contractor does everything in the cheapest and fastest possible way, so I would like to be able to tell him specifically what his painter should do. We have already paid for the exterior painting in our contract, so hiring a better painter is not an option. PLEASE HELP!
