Penofin First Step Prep for Exterior Hardwood is formulated to open the pores of the wood's surface. It is the ideal way to ensure deep penetration of Penofin's amazing natural oil finish. First Step Prep cleans, brightens and reduces the hard mill glaze found on most hardwoods. This allows Penofin to transform even dense wood species for ultimate protection and beauty.
