Is it OK to paint slightly damp wood?
Although not recommended, damp wood can still be painted. When painting wood, you must be sure that the wood is completely dry if you want to ensure the best results. It is possible, however, to paint damp wood if it's absolutely necessary.
Wash the surface with soap and a stiff brush and rinse. Wait for it to dry (possibly weeks or months) - check for dryness by sprinkling with a water - if it beads-up, it's still wet. If it soaks in, you're good to go. Prime the surface with primer designed for exterior use on pressure treated wood.
Wood: Interior wood should contain no more than 12% moisture prior to painting. Exterior wood may be allowed to contain no more than 15% moisture. When it comes to wood furniture or cabinetry, the moisture content must be as low as 6%.
Weather condition
Probably 2-3 days are enough to dry the wood completely. But if you live in a wet and rainy area, drying time probably takes more than 2-3 weeks.

How Long to Wait After the Rain to Paint Decks and Other Surfaces. The type of surface you'll be painting on may have an impact on the duration of the drying time. For wooden decks and/or surfaces, wait for a minimum of 24 to 48 hours after rain before applying deck stains or other similar products.
You can also test the driness of your firewood by banging together two pieces of wood. Your firewood is dry when the sound is hard and ringing. Moist firewood has a dull sound.
If wood has a moisture content above 16%, mold can grow. Mold then extracts carbon out of the wood, which at first changes the color of wood.
You should be aware that a moisture reading of 0-15% is quite normal and gives no cause for concern. However, moisture readings in excess of 15% indicate the need for further inspection. Levels between 25-30% indicate that there may be water ingress, meaning that remedial work could be required.

Is wood ruined if it gets wet?
Wood is a porous material. This means that, over time, exposure to water will permeate the wood's membranes, causing it to rot, soften, and fall apart. Additionally, water compromises the structure of wood, leading to mold growth and expensive restoration efforts.
Wet lumber will naturally dry out if given enough time. If the outdoor temperatures are above 60 degrees F, it usually takes about 4 weeks for moisture content to decrease about 4%.
Painting over damp materials will allow the damp to continue to cause damage beneath your fresh layer of paint, while wiping off mould and painting over it will leave mould-infested materials beneath. Before long, the mould will return.
Absolutely not. There's an adhesive quality to just about any sealant, and moisture is going to kill it. You have to get the moisture content down to 9% or lower. When wood is freshly chopped down, it's considered to have a 100% moisture content, and it takes seasons (sometimes a full year) to dry it out properly.
Pressure treated wood needs time to dry out before it's primed or painted. You can expect 3-4 months before the moisture levels fully go down. If moisture beads up on the surface, it's still too damp. You'll know the treated wood is ready to paint when it absorbs water instead of repelling it.
Following damp proofing and specialist plastering works, it is always advisable to allow the walls to dry out for as long as possible before redecoration is carried out. We normally advise delaying for a period of 4-6 weeks after rendering / plastering and using vapour permeable water based micro porous emulsion.
