Buy another brand besides Behr
While Behr stain isn't great stuff, my wife put the Barn Red Latex on her house (before I met her) and it lasted for seven years with only some chaulking on the side that got the most sun. There was no peeling.Stain shouldn't peel. Most people who use Behr Latex Stain have it peel off the next year. You now have a painted surface. Unless you can get most of it off, you need to jus scrape the peeling spots. Prime the bare wood and paint.
Don't prime if you are going to stain.Any recommendations as to what brand I should use?
Would still like to use the water based stuff.
What about the primer? what brand/kind would you guys recommend?
Or it could be the cheap latex paint being called stain......Peeling could be a result of improper temperature conditions, surface preparation, or exposure to moisture as it cures. Without knowing more details on the application of the product, I am not able to say exactly what could have cause this.
