Finishing Wood Siding
What’s the “gold standard” for painting/staining wood siding?
Martin suggests not doing it at all– leave the wood unfinished to weather naturally . Fair enough. But let’s say that you’re going to paint or stain it. Let’s assume it’s installed over a rainscreen, that we’re not in the desert, and that we’re talking about solid color paint or stain.
Joe Lstiburek says “treat with a penetrating water repellant preservative on all six surfaces, coat with an oil based primer on all six surfaces and top coat with an acrylic latex paint” .
No argument on the “prime 6 sides” front – that seems a best practice. But what’s this about treating with a water repellent preservative? I’m unable to find a painter or paint supplier who thinks this is a good idea. Everyone’s afraid that it will either interfere with the primer bonding, or with stain uptake.
So what do you typically spec/recommend/do? Is a preservative treatment overkill? What about a primer beneath solid stain?
