I finished pressure washing inside and out yesterday evening, it took about 330 gallons of water. There was no way to keep it out of my eyes that feel like I swam in a pool that was just shocked. I put a big fan inside to help dry things out. The Big Brown Truck dropped off 20 gallons of interior and exterior sealant, a case of 30oz log caulking & a gallon of dark walnut interior stain for the Missus's master bathroom. We have a warm window of 40+ to 70 degrees, so I will be spraying sealant. I have also started closing in the East gable...pic's to follow.
While watching the TV show This Old House, they did a demonstration of why you should NEVER pressure wash a house. While caulking and morter damage are not a concern for your home at this stage, it was amazing at how much damage a pressure washer did to an existing house.
The other thing that they showed was how far into the wood the water goes. Huge amounts of water goes into every joint between the wood, and the wood itself absorbs huge amounts of water.
Then went back and checked the moisture level on a weekly basis and it was several months over the summer until it was dry enough for them to be able to paint the wood. Even then, they opened up the wall cavities and found moisture still remaining in places.
This was an older home that they where not working on, but using for a demonstration. It has both brick and wood, but not a log house like yours.
My concern is that you have forced water in between your logs and there isn't any way to know how long that moisture will remain in there. Before sealing it up, I would try to figure out how to measure that moisture, and what the pros and cons are of sealing up the logs with water in between the logs.
I know that the paints and stain products that I have used on homes do not last very long if there is moisture coming from the wood they are applied to. This is the number one reason it's so hard to paint pressure treated wood. Once PT wood dries out, it paints fine, but if there is moisture in the wood, it doesn't last or it comes out looking terrible.
