Pull up the carpet. Remove the carpet strips, little rusty nails and industrial staples. Chisel free the old tiles. Scrap, scratch and pry off the fossilized black glue. Rent a sander so heavy that only a body builder from the fifties could comfortably wield it. Sand until your lower back seizes up.Sand some more. Keep sanding. Now stop. Now stare. 2x6 redwood tongue and groove flooring so rich and straight and proud it makes your heart break. Welcome back to the light dear trees.
