I would like to use non-pressure treated posts for my deck because I need the
posts to look good (they will create the gazebo and railing as well). Am I ok
if I treat the bottoms with Jasco and elevate the posts above the concrete
footings, or should I treat the posts with something else?
The kinds of stuff that will view your posts as lunch depends upon what
part of the world you are in and whether you paint or varnish. I am not
familiar with Jasco (indeed DAGS did not turn up anything with which one
would coat posts), but sealing ends is never a bad idea. Raising the
posts above the footings is always a good idea.
As to the posts themselves, some like to have it simply weather and turn
gray. If you want to seal (and reseal periodically) you can use just
about any kind of wood. Look into using redwood, cyprus, teak, pau
lope, and other types of varmint resistant woods, or even some of the
man-made stuff like trex. Personally, my deck is redwood coated with
SuperDeck which is a stain/tung oil/varnish combo. Time will tell if
this is any good. Thompson's Water Seal lasts until the first rain, IMHO.
In my area of the world, around Toronto, minimum six inches of concrete
above grade and in a saddle is code. Have used cedar this way and the deck
that is now about thirteen years old is still 100%, mind you the home owner
I built the dack for pressure washes it and puts protectant on it every two
