I have bought an enormous amount of lumber that (according to my crazy schedule) should have already been used 3 months ago. It has been laying on the yard, under a tarp, and it doesn't look so nice...
Black mold has appeared on the pieces that were on the outer edges, the ones in the middle of the pile look okay.
Can I use the lumber?
What should I do with the pieces that are bad?
How should I store it so it doesn't go bad?
Indoors is of course the best, but that's not possible right now...
In this case, it’s råspont and klädselbrädor.

Make sure to get the timber properly off the ground. At least a couple of decimeters.
Restack if it has become damp. Don’t cover with tarp but get metal sheets! With an air gap in between!
You can most likely use the timber. A little black/gray doesn’t matter as long as it hasn't rotted!
Good luck!

It is fine to cover with a dense tarp if the wood is really dry. However, it must not lie down against the ground because then you'll trap ground moisture which will condense against the tarp. You need ventilation that can blow under the covering. The plastic should only serve as protection against rain from above.
Scatter lay between each layer, and turn so that you counteract the wood twisting, cover with a sheet to allow air to circulate freely... And of course, plenty of air underneath, feel free to place something that prevents grass from growing up...

Look at the end of the wood and you'll see how the growth rings are curved. When wood dries, it wants to contract following the curvature of the growth rings, so counteract that by laying them in alternating directions. It's just something I "learned" as a kid, and I don't really know if it's necessary for stacking. But if you're going to make a door, like a simple shed door without a frame, you have to arrange the wood ends correctly, and also make sure the fibers go in the right direction so that water runs off, to prevent the door from warping severely. Or when you're nailing a wooden deck on a terrace, for example, the wood needs to be used so that all the boards strive to curve downward, otherwise there's a risk that the floor becomes uneven and that some boards even twist loose...niblom said:
