Hi Heads! I'm having a problem with a pressure treated post. There is some water in the post (don't have a great supplier around here for dry posts). I primed it three times with Jay Cooke primer and then painted 3 times with a exterior latex paint. Unfortunately the green streeks from the water keeps coming through. I don't want to paint with oil base because I want the wood to breath so the water can release. If I paint it will oil I'm assuming I will have major bend in the wood. Is this correct? Does anyone have any suggestions? Thanks, Bren

Brenda, I think the absolute best pressure treated post is not pressure treated at all, but PVC or Vinyl. How about checking with a fence company and changing over to PVC or Vinyl !!!!!

Brenda, I like to let mine dry for about three to four weeks. I then sand them and prime with solid color acrylic latex stain. I topcoat with 2 coats waterbased acrylic paint. Sometimes, though, I just use two or three coats of the acrylic stain.
Like Joey says, PVC posts are great. I like to insert a pressure treated core in them for strength.

Jay Cooke's primer is good stuff. But, speaking only for myself, its not a good stain killer primer. And, that is what you need. I would just go down to your local paint store such as Scherwin-Williams and ask for a water-based stain-killer primer for treated wood. They will give you the right stuff.

It's better to let them dry out before you do anything to them. After that, I usually seal all the cracks, knots, etc. with plastic wood filler, sand, prime and paint. Never had a problem with bleed through as long as they are dry.

Pressure treated lumber is not dry kilned. Basically it is green in lumber terms and it has to be so in order to pressure treat it. Spruce is normally used for pressure treated lumber and it's properties are not the best for having a stable product that will stay straight. I am also pondering on what to use on two sandblasted signs due early next month. Rough cedar was always my choice in the past but availability in my region is not good. Rough sawn stained lumber (not dressed) will outlast planed or dressed lumber. I have had some stained rough boards on my house as trim for 15 years and they are just starting to fade. Vinyl posts may be the answer, who knows!

I don't use pt posts any more. I use Cedar and treat the first 3' with a sealer made for dock posts. This is a new method this year, Because the cedar posts are super straight, stay super straight and I can paint it right away.
If this doesn't work I'm going to follow Cam Bortz's idea and use granite.
Screw PT, the stuff is garbage.
