Awhile back I asked about the best moisture content of the wood siding on my house for painting. Using SW oil A100 primer, and 2 coats Resilience. Piffin had said 12-13 or lower. I was going to put some primer on the section I sanded Sunday, got a reading of 15. Is there any way for me to dry out the wood a little so I get to the 12-13#? I was thinking of shining some of those 500 watt halogen work lights on the wall, roughly 8 x 15, for a few hours prior to priming. I could do this on each section as I need to all around the house, priming in sections. Once it’s primed, I just need a dry day for the paint. Any thoughts?
Thanks

I think you're fine at 15 percent.

it's dry to the touch, and humidity is running about 50-60% this time of year on a clear day.
I'd be painting. If we had to wait for 13% moisture and a dry day we'd never paint anything. 60% humidity is a dry day here!
After months of prep, I don't want the last steps to screw things up. I feel like 15% is doable, but I'll wait for more knowledgeable folks here to second that.ThanksKevin
Ah, then the thousands of gallons of paint I've put on in the last 35 years were for naught. :-)
Thanks Florida.
Just found this on the Sherwin Williams site:Coatings can be applied to treated woods after the moisture content has dropped to a paintable level – usually 15% or below. To determine if the surface is waterproof, splash water on the surface. If the water is absorbed and the surface becomes noticeably darker, the surface is not waterproof. This test is especially recommended for pressure-treated wood and smooth cedar. It is crucial to ensure proper penetration of the coating.Answered my nextquestion, about painting PT wood.Thanks everyone!
That's why I said you'd be OK at 15% ...
