(Above: The liberally spray-foamed Wall #6. I don’t think there will be many bugs getting in that way.)
Building Summary: Today I started off by measuring, marking, and cutting plywood pieces for the interior of Wall #6. This was followed by a brief journey to oldhouse to procure a can of spray-foam and then by my returning to Jacobhouse to empty that whole can into the voluminous cavity above the sliding glass doors*. Clean-up ensued (more in commentary), and then the morning was complete.
Commentary: Yesterday I was unable to complete the spray-foaming of Wall #6’s interior on account of a lack of ‘material’. Today, though, I found a spare can of Great Stuff that Madre had stowed away, spirited it to Jacobhouse, and then utilized it just I have always tended to use sprayfoam thus far; that is, a little too liberally. I dispensed what I thought to be a limited amount, but as ever, the sprayfoam exceeded all expectations.
Most of the foam behaved and remained in the crack where I placed it. On account of the gap’s greater-than-1″ size, though, it was not a stable application. This means that in some places, the outside of the foam was beginning to harden whilst the inside of the foam was continuing to expand. At least that’s what it looked like had happened when I returned to Wall #6 after a short absence tidying up the front of Jacobhouse. What I know for certain, though, is that when I returned to the back, I found that great gouts of sprayfoam had erupted in four or five places and were hanging quite precariously between the ceiling and the floor. The worst part, though, was that one had ruptured and dripped down all over the sliding glass door’s right pane.
Fortunately, I knew enough about sprayfoam to not try and wipe it off right then. That would have resulted in a smear-mess. Instead, I waited for it to cure for an hour, researched how to fix the problem on my phone (nail polish remover seemed to be a universally accepted remedy), and then obtained that solution** from Madre along with a plastic scraper. Alas, even with the nail polish remover, the plastic scraper did not work. It was actually beginning to shred itself against the hardened foam. What did work, however, was a spare piece of PVC trim board. That, along with the aforementioned nail polish remover, scoured every smidgen of spray-foam from the glass.
Final Note: Tomorrow, I intend to trim away all excess sprayfoam and fasten up the pieces of plywood that I cut today. After that, I will likely begin planning for the closet-wall and/or glue in the shower drain.
* I should say ‘sliding glass door wall‘. It was the gap between the entire wall frame and the top of the container – a crevice that was about 1″ on either end and warped up to 2″ in the middle.
** Please pardon my paronomasia. (That’s the formal and quite presumptuous way of saying ‘pun’.)
