Maybe after awhile My suggestion is to coat your post with black or white rubber FLEX-SEAL SPRAY IT RETARDS WATER THAT CORRODES METAL!
Maybe but my decking is supported by 6”X 6” 12 footers in concrete post holes Coat bottoms with FLEX-SEAL BEFORE YOU PUT IT CONCRETE IT WILL SEAL THE WOOD AND IT SHOULD LAST A LONG TIME BEFORE WOOD ROT EVEN TRIES TO GET STARTED!
Weather suggestion… (FLEX-SEAL) black or white Do the bottoms too
Well I don’t know that for sure but my experience is that they dip the lumber in what looks like fire retardant to me I used to build seats for boats and it looks like the same stuff Then limber is put into type of over and I think it’s called an AUTOCLAVE WHICH HAS A DOIR AT ONE END AND THEY ROLL THE RACKS OF LUMBER INTO THE CLAVE AND THEN THEY SHUT THE DOORS AND THE DOOR HAS LOCKS ON IT MAYBE AS MANY AS TWELVE THEN THEY FILL THE CLAVE WITH GAS OF SOME MIXTURE OR JUST OXYGEN OR REGULAR AIR THEN THEY ADD ENOUGH GAS TO FILL THE CLAVE CHAMBER TO AN AMOUNT THAT IS A LITTLE HIGHER THAN 100 psi BEST GUESS THEN IT HAS THE HEAT TURNED UP SO THE LUMBER WILL DRY UNDER PRESSURE. THUS IS MY BEST GUESS AS I HAVE ONLY SERN THE PROCESS FROM A DISTANCE
Out of my area of help quantity might be around 50 or so best guess
I am not sure to whom this question is directed but I can't answer for home depot, I cut them myself.
A long time if you use FLEX-SEAL SPRAY BLACK OR WHITE COAT THE BOTTOMS TOO!!!
