Category: Paint-Painting - Topic: Painting Cedar Siding
For the longest lasting and best results painting cedar siding, priming and painting cedar on both sides is recommended. What you are basically trying to do is to prevent tannin stains from leaching through to contact the new cedar.
Pick a good oil based primer with stain block. A common procedure is to then coat with two coats of weather resistant acrylic latex finish.
Of course, do not paint in rainy or cold weather.
