Hi Bob, We have a 1921 wood home 40 miles north of Pittsburgh, so we get winter. The exterior wooden boards are 10 inches high and grained up and down as you look at the board; it's not a grain I'm familiar with so I can't identify the wood. Paint doesn't adhere long enough to my liking. What is the best way to completely remove all the paint, prep and what type of primer and paint should I make sure the painter I hires uses? Thanks in advance!

Diane
