hi
noticed this morning all the pine doors in my house are leaking a dark sticky sap type solution, the doors are not painted and are pretty old so don't think its sap leaking out of them.
tried searching the internet for answers but no luck, if anybody knows whats causing this or can point me to an appropriate website to find out much appreciated
Don't know for sure but it seems your choices are
1. supernatural ecto-plasm
2. sap
for the stuff leaking, as much as I liked Ghostbusters I might go for 2.
How old is pretty old? if it is all the doors I would have a wildly speculative guess that the temperature/humidity/air pressure/voodoo have be right for long enough for it to happen to this batch of wood.

how old is old??
i would have said they are "seasoning" but if there old then i cant say.
you can get them acid dipped to remove the sap?
That'll be pine ejaculate. Ever wondered where the expression 'got wood' came from?
well old
must be the viagra wax i used on them
It is sap, but otherwise known as resin/rosin - you won't remove it by dipping it (and IMO anyone that dips doors ought to be bloody shot - it often warps them if not completely ruining them). For the same reason, before painting woodwork you should always put knotting solution (shellac, iirc) on any knots (which are especially resinous) to seal them and stop the resin leeching through into the paint above and staining it
You ought to be able to remove the resin by wiping it with turps - that's *proper* turps, not 'turps substitute'. Or when the weather cools, carefully scrape it off when it sets again.
If the doors are early 1900s, and have a very noticable grain, there's a good chance it's pitch pine - that's the sort of stuff you often see in churches as various woodwork (eg pews) and looks far nicer than any scots pine stuff you get nowadays:
Most of the woodwork in our last place (Edwardian, 1914-ish) was pitch pine - one door in the hall had so much resin in one patch that with the sun behind, it looked more like a patch of ambar viewed from the other side...
jond
think the doors are pitch pine thanks for the advice i'll try the turps
