We're getting ready to pressure wash, caulk, and re-treat/stain our log house for the first time. (The first time since we moved into it, anyway -- we moved in last fall, and the house is now a little less than three years old.) There has been some pretty severe checking that we'll need to fill in. A couple of questions about caulking these checks:
1. Since we need to pressure wash the house, should we caulk before pressure washing, to ensure that water doesn't get inside the checks? If not, then how do we keep the water out?
2. Because there seems to be a lot of checking, we're going to have a lot of visible caulk, and I'm concerned about blending the color with the stain on the logs. Should I get a clear or white caulk that will absorb the color of the log oil, or should I get a caulk that will be close to the color of the post-stained logs? (And if I do that, then do I have to worry about it getting even darker when I spray the logs?) Specific product recommendations welcome.
