Good morning. My name's Kel. You MAY spend less applying protectant, but you won't have much in the way of protection. Lumber to be pressure treated is loaded in tanks then submerged in the preservative then the tank is pressurized. If memory serves -- to 15 PSI. This forces the chemicals ALL the way through the entire piece. Your proposed application would only be topical. Pressure treated lumber is some of the cheapest available,for the protection you get. Does this make sense? Have I answered your question?
