To determine if pressure treated wood is dry enough to stain, try the “sprinkle” test. Sprinkle water on the wood: if the wood absorbs it within 10 minutes, plan to stain as soon as possible. If the water beads or pools on the wood surface, the wood needs more time to dry.

Nevertheless, how long should pressure treated wood dry before using?
Stack wet lumber on a flat surface such as a driveway or patio, use spacers between boards to let air circulate and check the wood for weight and by touch for moisture. We have let pressure-treated lumber sit for four or more weeks in 90-degree weather until it was dry enough to use without shrinking.
On top, what happens if you don't dry wood? If a product is made before the shrinkage takes place damage to joints can occur and the product will fail. If the shrinkage is not excessive, the wood may warp even though the joints may not break. When lumber is dried the shrinkage has already occurred.

Your wood will dry many times faster if it is exposed to lots of sunlight every day. So, if possible, have the drying stack in the sun. It also helps if you have it exposed somewhere that it is extremely windy. The more sun and wind can get to the drying stack, the faster this process will go.
An existing dry joist (around 12 percent moisture content) might be 50 percent stronger than its original "wet-wood" value if it was originally installed as rough-cut, green lumber.
To identify well-seasoned wood, check the ends of the logs. If they are dark in colour and cracked, they are dry. Dry seasoned wood is lighter in weight than wet wood and makes a hollow sound when hitting two pieces together. If there is any green colour visible or bark is hard to peel, the log is not yet dry.
Although the chemical preservatives present in pressure treated wood is resistant to rot, they're not waterproof. They readily absorb moisture, which makes the wood swell and eventually give room to decay. The treated lumber has to be waterproofed for it last longer.
If it rains within 48 hours after you apply the stain, the water will soak into the wood pores and try to displace the stain. ... If it rains right after you apply the stain, the stain will peel and flake off. If your stain has been drying for close to 48 hours, this may not happen.
It's important that you make sure there is no chance of rain when you begin to sand. If the wood gets wet after it's been sanded, but not before you've had the chance to stain or paint it, you'll be back to square one — you'll need to wash and sand it all over again.

. It might be good to sticker it up as long as your storing it.
While pressure treated poles can stay up to 40 years without any signs of rot or decay, decks and flooring might only last around 10 years.
Over time, most treated lumber will shrink slightly across its width as it dries out. Take this small amount of shrinkage into account when laying decking or fence boards. After being outdoors for six to 12 months, treated lumber will develop cracks, called "checks," along the surface of each board.
Wood can Start to Rot in 1-6 months If: Water and/or air space is hot & humid. The area is at or near the ground. Wood is exposed to dirt.
If you stain pressure-treated wood too soon, the stain will be unable to fully penetrate the wood, and you will not get the protective benefits of the stain. What is the best stain for pressure-treated wood? An oil-based stain is the best for pressure-treated wood.
Treated lumber, which is notorious for warping and bowing, is treated by dunking the lumber into a vat of liquid and then applying pressure to force the liquid into the wood. That means the wood is very wet and generally arrives at the lumberyard wet. Wet wood warps very easily.
Chemicals and Treatment Process Used For instance, pressure treated plywood has a life expectancy of about 20 years; but this is with constant exposure to water, such as being left out in the rain. On the other hand, MRF and OSB have an expected life of around ranging from under 30 up to 60 years.
While pressure-treated plywood can still be damaged, it won't decay. The chemicals injected into the plywood don't make it any stronger. They just make the wood impervious to the aforementioned pests, many of which cause decay. By repelling those pests the wood lasts considerably longer.
For similar reasons, wet lumber can hinder how well paint adheres to the wood, but the added problem of the preservatives in pressure-treated wood makes it difficult for the paint to bond; this is why it's advisable to stain pressure-treated wood instead of paint, as painting requires additional preparation.
Although the wood is resistant to rot and insect attacks because of the pressure treatment, it can warp, split and develop mildew if not protected from the effects of water. ...
