If the outdoor temperatures are above 60 degrees F, it usually takes about 4 weeks for moisture content to decrease about 4%. It might take 6-12 weeks for a 4% drop if its cold and rainy. And if it’s below freezing, it might take many months.

Expected Utility theory assumes individuals will choose the outcome which gives maximum utility given the probability of outcomes. Prospect theory allows for the fact that individuals may choose a decision which doesn’t necessarily maximise utility because they place other considerations above utility.

Your framing lumber and the oriented strand board (OSB) are going to be fine. Houses I built got wet routinely during the framing process and I never had an issue. Wood rot can and will start when the moisture content of the wood reaches 20 percent.

Our OSB is rated “Exposure 1” and that means that it will withstand normal delays in construction. Normal delays and the rain you indicated will not affect the structural properties of the panels. Certainly it would have been better to have covered the roof with a tarp or roofing felt before it rained.

Given enough time (assuming it’s not getting wet again) that wet lumber will naturally dry. If the outdoor temps are above 60 degrees F then it won’t take much time. Maybe 3-5 weeks to get from 18% down to 14%. But, if it’s cold & rainy outside it might take 6-12 weeks.

A simple test to see if the surface is dry enough is to sprinkle some water on the surface of the wood. If it beads up, the wood is too wet. If it is readily absorbed then you can proceed with finishing.

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.

Kiln drying your own wood at home can be a great way to sustainably harvest the materials around you, and dry it fast enough to build furniture with. If furniture is made with wood that is too wet, it will continue to dry and crack, possibly ruining the piece.

Freshly cut branches can take anywhere from 6 months to a year to completely dry out.

Types of Wood You Should Not Burn in Your Fireplace

• Soft wood. Soft wood from trees like cypress, pines, or firs burns very rapidly, creates a great deal of smoke, and rapidly coats your chimney with soot.
• Endangered species wood.
• Oleander.
• Mexican elder.
• Anything Named Poison.
• Driftwood.

six to nine months

Brush piles should be burned when wind speeds are less than 15 mph and not gusty for an extended period of time. Also, wind direction should be considered to keep embers and smoke from becoming a problem downwind. Relative humidity is the second most important weather variable to consider before burning piles.

Wood that isn’t stored correctly can start to rot due to regular and prolonged contact with moisture. The CSIA states that you can keep firewood stored for up to 3 to 4 years without any issues of the wood going bad if you follow these recommended procedures for storing the wood.

Let in the sun Allow sun and wind to reach your wood pile, the more sides of the wood it can reach, the faster your firewood will season. Your freshly cut wood can be left out in the wind and sun in a roughly built firewood stack for a few months before stacking it to speed along the drying time.
