Proper way to seal bottom plate to slab?

Question

I noticed that the caulk has failed where the bottom plate meets our concrete slab foundation along an exterior wall. I’ve removed the old caulk and vacuumed the area. The bottom plate is sitting on a foam gasket, but I’d like to fix it to help with air sealing.

This is a wood to concrete joint. I need something that will adhere to both and stay that way through temperature changes.

Should I re-caulk it with a flexible caulk or use a small bead of great stuff from my foam gun?

Answer 1

I went with a small bead of spray foam. One of the “good” images from PNNL's guide (reproduced below) showed spray foam along that joint.
