" Good to -- Nice backyard deck. Richard Kleiner is here from the wood promotion network. And we're gonna talk about the properties of pressure treated lumber yes now Richard up until a few years ago a lot of the PTO -- Pittsburgh included a copper arsenic that. A lot of people worried about using it that product. Voluntarily was taken off the marketplace that we have a whole new generation of pressure treated lumber today don't. Yes Bob CCA was taken off market for residential use and now since we all have this. Actually two good choices either copper or copper -- all or in this case alkaline copper plot commonly known as they -- here. And what's like. Cedar and redwood have a certain amount of natural preservatives that'll fight off insect damage and damp right that's true Bob you can use almost any kind of wood to build a deck yet but codes recommend that you use a pressure treated southern pine primarily. For structural use especially for structural use that to -- sink is you know. Deck failure can be such a traumatic situation when you've got a good stick you know good strong member down there like the southern yellow pine these are what. Four by four's. That look like six by sixes and two by 12 by -- yes of these will be your -- and these will be our posts now explain to us what we read on the backs of these labels. Well in this case of this material is going to be used above ground so you want to make sure the label says for above ground use. This -- the post of course are going to be in ground resting on masonry so is that determined by the amount of treatment that goes into the wood. Yes this is tagged for booked for in ground use and it will have more preservative in it would then they two by material OK so bulb. So the preservative that's put on it determines the durability. The strength of the lumber against the weather and against bugs. -- you have to look at the hazard you're dealing with and determine by that the use category right for example in -- marine environment they use. Two and a half pounds of preservative per cubic foot of fiber for example -- now the preservative itself. Tell us what it this. When this case this is alkaline copper -- It's excellent preservative like most album was. Album are you -- Have a limited lifetime warranty on it so this deck can last 3040 years the copper part of that that tag. That is what helps preserve the lumber. Yes the copper inhibits so fungal growth. Chases away the termites. And keeps the wood strong stable and safe for years now great OK thanks Richard is going to be fun to build."
