white pine pitch

[Splinter]

Had some white pine milled up and its seeping some pitch.
How long before the pitch stops coming out of the wood? It will not be painted or sealed.
Kiln drying is not a possibility.

Thanks.

Until it's kilned. No kidding I'm afraid. If you use it for molding and paint or treat it, it will eat through the knots in the boards.

you can set it out and wait like some of the smaller mills do, but it could take up to 6 months to wait for, but then it will still absorb the moisture from the air if its humid or it rains.

I had some setting for 3 years, it still weeped through knots. Ya gotta set the pitch to a crystalline form I think

It all depends on the size of the pitch pocket ...  :-\   I have some post that support my garage that are still weeping , five years later . It also depends on the thickness you had it milled , thicker will take longer to weep out and dry up .

Thanks for the feedback,
Was going to use it for some picnic tables & seats..... Guess the kids are getting a new fort.

well at least you know that the napkins wont blow away on a windy day :D
maybe  you could put on some lacquer on it to make the pitch not come through, but maybe it would get through that idk?

You can stop some minor bleeding with shellac.

resin/pitch canals. Tiny little pores that bleed pitch.  ;)

Put the pine boards in an attic or someplace that it will get very hot. Leave them there for a couple months if possible.  This should set the resin good enough.

I've been using the owners sauna at work for some white pine that I needed to push through ;D 3% per day and got it to 150* for hopefully long enough to drive off all the volatiles that would vaporize at up to that temperature. The attic would work too if the wood does not see the attic temperatures in service. A few years ago I resawed some pine beams in an old cabin. I had laid a few boards in the sun and some sticky droplets formed on the fresh surface. The wood was 160+ years old.

Or the kids.

As far as building with the white pine, I know that when when using any type of pine for interior trim it should always be shellaced as Tom says before painting to prevent the knots from bleeding through the paint.
