UV is the devil when it comes to exterior wood. Pigmented stains like PolyWhey Exterior Penetrating Stain and the Rubio Monocoat Hybrid Exterior Wood Protector will help lengthen the life of your deck against UV graying, but neither of these are a "do it once and never again" solution against graying and peeling. Length of time between treatments will vary based on your location, exposure to the sun, and other factors, but given a choice between these two, Rubio Monocoat Hybrid has a slight advantage because it is a single coat and you are done. If you are needing a product to remove graying before you stain, we recommend Rubio Monocoat Exterior Wood Cleaner. NOTE: This applies to pigmented stains only. Clear stains provide little to no UV protection.
