Outdoor Caulking Done

Today was a good-weather day. Armed with confidence and a can of DAP expanding foam, I headed outside to finish up the weatherproofing of the new hose bib. Naturally, the hole was just as I had left it some days ago.

Per the directions on the can, I shook for one minute, and then keeping the can mostly upright (not like in the photo; it's hard to pose and shoot at the same time) I sprayed some foam into the gap. It said to fill the gap to 90% and let the foam do the rest. I filled it to about 150%, which the foam kindly increased to about 165%. I ran inside to grab some paper towels (why didn't I think of this before?). Wiping around the edge made for a nice clean foam-filled gap that looks like it should stand the test of at least some time.

I'll of course monitor it for a while. I'm concerned about the amount of play in the hose bib, and I suspect it'll pull the foam free unless it remains flexible. We'll see. I've seen this stuff crumble if applied at too cold a temperature.

While I'm at it I'll probably run out to do the driveway light on the front of the house. I foamed that one about a year ago and it's pretty much crumbled. I did a real hack job on that one in extremely cold weather, with total disregard for climatory admonitions on the can. I'll add words about that job below here as an edit when I'm done.

Cheers
