Each year after the winter, the paint on our cedar clapboard is peeling off. We have sanded, primed, and stain more time than we want to count. Is there any way to prevent this yearly nightmare? My husband is ready to vinyl side the house.

- Paint peeling from smooth-side out cedar
Two likely causes.
cedar has tannins and resins that can make it hard for paint to adhere. red cedar is worse than white. There are special primers and paints formulated for cedar and redwood. buy the best from a real paint store like Sherwion williams or Ben Moore.
Second, the most common reason for paint failure like this is t56hat tjhere is water vapours or moisture moving from inside the wall to the outside, generally becuase the envelope was poorly designed, such as no vapour barrier or no VB. Could also be from crawlspace moisture entering the walls and moving out through the siding. We use appropriate VB on the inside of the studs and tarpaper under the siding, often with rainscreen space - a drainage plane - and we backprime the siding before installing it.
Excellence is its own reward!
