Question

HD lumber warping ... this is ridiculous


i have very rigorous acceptance standards when buying lumber. i reject at the slightest imperfection and my find ratio is somewhere between 10-20% for 2x4s.

but even when i do get 100% straight ones, if i don't use them within ... no kidding, 48 hrs, they get warped out of the acceptable.

i don't store them in any way that can cause warpage, just typically lay them flat on the ground.

what is the deal with this lumber ?? why does it warp so much ?

Store it off the ground with blocks, chocks or sleepers depending on where you grew up. Bonus points if you put down Visqueen first. Then cover it with Visqueen. Store it out of direct sunlight.

It warps because it has high moisture content.

Buy Kiln Dried (KD) lumber, often not available at big box.

You bought that lumber from a wet load---Improperly stored or wrapped during shipment--

Take it back--find a dry load in a different store.

Consider building using steel studs, no warp.

I prefer to order all framing lumber from Lumber Yards, rather than Big Box Stores.

big box stores keep far less lumber in stock compared to lumber yards. what little good material they do have in stock goes pretty quick as its picked over


keep the straight material for corner studs, king and jack studs.. use the ones with slight crowns for the commons.. for long material for plates simply kerf cut them so you can straighten them easier

the ony other thing i can think is that your not storing it correctly, if you go from one extreme to the total opposite extreme the wood is going to move.. you cant bring wet lumber directly inside to a low humidity space right away and expect it to stay straight. you have to climatize it

besides if you want perfectly straight material your going to have to use either steel stud or pay way more and use timberstrand engineered studs

Yeah anytime buying lumber at a box store it is usually pretty frustrating trying to pick out the good ones. Lumber yards are better; or as mentioned, steel framing really does have its benefits.

Yes, this is true-especially if you are doing reno's and will have to open up the wall to put in backing, much more of a PITA than redoing a kitchen in a wood frame building.

Steel is less organic than wood? Both come from the earth and both receive significant human manipulation before YOU get it.

The organic characteristic of the wood is what causes it to warp.

I've had the same problem. I can't tell how much warp you are talking about, but in the future, I won't be buying more than I can use relatively quickly. I bought better grade...the best they had at Lowes, and it warped standing in a corner in my garage, waiting to be used. Corner is near my garage door and temperatures varied during storage from winter nights to the 50's and 60's during the day as my garage isn't heated.

However, I was able to make it work...so, lesson learned.

Problems I've found picking over wood at my local big box store is it's often times hard to get at the good/straight pieces, since they're usually in the largely undisturbed piles. A nice nearly fresh pallet is usually the best bet. Since sometimes the wood is on higher shelves, it's a big pita to get to, and many of the reachable boards have been moved around and put back not stacked at all in any order, causing them to warp even more. What can you do..

As others said, sometimes they'll have several pallets that are damp/soaking wet, which I'm sure doesn't help the wood. I just avoid those.
