Topic tags/keywords: wood lumber storage barn sticker slat kiln air

So I have a small amount (40ish, 4-10” wide, 8’ long, 4/4, maple/cherry, kiln/air dried but all dry to sub 13%) of wood that I need to store. I just graduated college (going to be a tech. edu/woods teacher) and am storing it in a barn. I used some 3” x 3” boards to get it off the damp wood barn floor and used slats (1/4” ~ 3/8” thick, 1 1/2” wide, random length) to separate the lumber. I also stacked some shorter boards on top of theses, using the same sticker method. I covered it with a tarp and called it a day.

I used 3 sets of slats to along the length of the stack, so they are more than 18” between slats/stickers. I also had to use 2 stickers side by side since none were long enough to cover the width of the stack.

So, I was wondering if this was good for 2-4 years of storage or should I use thicker/narrower (1” x 1” seems to be recommended) stickers, make sure they cover the width of the wood stack with a single sticker and make sure they are 18” between stickers? If not, is this good enough until I can deal with this (in about a month)?

Thanks for the help!

...storing it in a barn…the damp wood barn floor…covered it with a tarp

I’m no expert, but this sounds like a decent humidifier to add water to some dry wood.

When you have a chance, I would recommend putting down some plastic on the floor before re-stacking it. Otherwise, all that moisture from the floor is going to be rising up into your stack. The tarp serves only to hold that moisture in.

If the floor is damp (why is it damp?) then yes, you need a moisture barrier.

Definitely use the larger stickers you’re not getting enough air flow with what you have.
Leave a good 1” gap between boards.

Never cover with a wood stack with a tarp because it restricts air flow, which is what you want.

As long as the wood is not exposed to direct moisture, you should be ok but if the wood might be exposed cover with some pieces of metal roofing or plywood.

Good luck on your future endeavors!

The wood is dry, right ? ..Then my opinion is that you don’t need to sticker it. You should be able to dead stack it. Indeed, leaving gaps between the boards will allow an express avenue for moisture to travel to the boards. I would stack it level and tight and wrap it in plastic.

A dehumidifier couldn’t hurt, especially if you can confine the space somehow..

If was going to store dried lumber in a unconditioned location for that long I would wax the end grain so it doesn’t split but that’s me. Other than that keep it out of the dirt and away from direct exposure to moister and insects.

Yonak is dead on. You do not need stickers. Flat stacking it will retard the movement of moisture back into the lumber from the surrounding environment.

I don’t think you really need to worry about it too much. You are in a humid environment and going to pick up the moisture whether you like it or not. Unless you can get it into a Ziploc air tight bag you are going to get moisture. My solution- don’t fret the long term storage but be diligent with the short term. When you do bring it inside, let it sit a while before you touch it for milling. Like weeks or months if you can.

The barn floor was damp because it had rained the night before and I have to keep it cover to keep the bird crap off of it.

I’m getting a lot of different responses, I’m quite surprised

Dead stacked, there is no air flow to carry higher humidity through the stack, so the wood will not gain moisture very fast at all if there are no stickers. Since the wood is already dry, you do not need stickers, and with the increased air flow over the layers with the stickers, your wood will pick up moisture from the air much much faster.

I would consider raising it higher off the floor. Both for moisture but also to discourage bugs.

Sounds like this is the concensus so I’ll restack when I’m back home.

Thanks guys!
