I’m doing some ext. work with logs.
some are ponderosa,some are lodgpole.
I’ve tried on 2 sep. occasions to caulk the cracks.
first time with a flex caulk. latex.It pushed its way proud of the surface in a few days.
2nd time I used a poly-urethane caulk, and it too is slightly proud of the surface, even though it was not at the time I left it.
I’ve used latex chinking in the past ,as chinking, not as caulking.
It stayedin place , and did not move .
problem with chinking, it has a texture, which I’m trying to avoid.also I would be using it for 1/4″ cracks not big chinking voids.
I’ve tried epoxy, but I have a lot of cracks to do ,and then you have to sand off excess epoxy. altho epoxy does hold very well , I’m trying to avoid that mess if I can.
Any suggest.? ……………thanks rob

I've usually used Perma-chink and you can get it textured (sanded) AND untextured.
I've never had a problem with the pushing out you speak of.
I've always used the 28 oz. tubes, but you can cut the tips off to a tighter orifice for small voids like you describe. Over 1/4" you should probably use a backer rod anyway.
If the cracks you're trying to fill are just surface checking in the logs, the caulking is probably pushing out as the moisture content of the logs changes.
Before you fill any checking, you might want to squirt/inject some wood preservative in the cracks, especially the ones facing up.
