I posted a couple weeks ago that I had a tv stand project i wanted to start, looking to do something very rustic, with a look of weathered/barn wood. I bought some samples of wood, stain, etc, and have been experimenting with finishes to decide what look I want.

Right now, the front runner is cedar, with a vinegar/steel wool solution, and a couple other layers of “stuff”. The cedar I bought to sample was a cedar fence picket (at HD), about 6” wide. They had them for $2.99 each (6 foot lengths) so the wood would be pretty inexpensive. It also has a rough cut texture, which is something i wanted.

So my question is, as I was lookng through these pickets, most were pretty damp. How long should I expect to dry them before starting the project?

I’m in WI, and dont’ have a heated garage/shop so I’m hoping to get this going soon before the weather gets too cold.

Thanks in advance for the responses!

I couldn’t say for certain, but I wood think you might want to invest in a moisture meter. If the wood is damp Iwould think it will take a fair bit of time to dry out, especially as it’s close to the end os summer. JMTCW

You can pick up an inexpensive General pin type Moisture Meter at Home Depot for less than $35. Lowe’s has same one for couple bucks less. Got mine back when only cost $10 & change. Prices can and do vary from one state to the next.

No way to tell you how long it will take for your boards to reach EMC for inside use unless have an idea of what the MC is now.

If go chapter 13 page 4 table 13-1 will give you ball park ECM of wood outside.

http://www.fpl.fs.fed.us/documnts/fplgtr/fplgtr190/chapter_13.pdf

Page 5, figure 13-1 provides average MC/EMC for interior use. Table 13-2 same page defines in use EMC lot better.

Wood must reach plus or minus 1 or 2 % Equilibrium Moisture Content for its intended use.

So if know the moisture content you have now and understand what you need to have before building your TV stand for indoor use only thing left is giving wood a chance to lose MC.

You can sticker & stack boards off the ground or stand up boards in the garage off the ground to allow moisture to evaporate with normal air circulation. Air circulation critical heat not so much! Once wood reaches MC of 10-12% bring inside for couple weeks or until MC down around 6-8%.

Total time required without knowing current MC would be nothing more than a SWAG!

That is Western Red Cedar and it will dry amazingly fast. Stack, sticker, and put a fan on it. It should be dry enough for you in a week or less.

If it’s the same cedar fence boards I bought there not too long ago, yes they dried relatively quickly but shrink and warp?!? They were just over 4” wide and paper thin by the time I got them straight enough to work with. Bow, crook, cup and twist. It was cheap but no bargain. It was my last go around with green lumber. I stack and sticker kiln dried wood for two weeks if possible now. It still wants to cup.

Good to know, thanks. I was back at Menard’s this weekend & discovered they have kiln dried cedar boards. That would probably be a better option. Now I’m working between pine, fir, and cedar with some different stain/weathering techniques & stuff to see which look I like best.

Hopefully I can make time to get this project going before snow falls!

even with the kld dried lumber at menards, it would be wise to get the lumber in your shop, sticker stack it and get some air moving on it for a while.its hard saying if the lumber was kept in dry conditions from the plant to the store.

“Kiln dried” in softwood can be deceiving. While they dry hardwood to 6-8%, softwood is usually only dried to like 19%. Heck, you can dry it outside to 11%. Usually Menards has the moisture content right on their website. Might pay to check under the product you bought.
