    Well, I'm tired now! And it was especially humid today.

    I made a small hexagonal hole in the joint compound lid, used a home depot bucket, went to town with a mixing bit. Worked out really well. I was surprised how tired I got just holding the damn drill!

    I used about 2.5 bags (30lbs each) of the all-borate insulation and went past the joists a little bit so I'm guessing I'm at around r-30. It took 4 trips with the big 30 gallon garbage can I used to transport the fluffed up cellulose. I used an ice scraper with a nice brush on one end to smooth out the cellulose.

    Finished framing the wall, used some scrap pieces of the purple drywall (want not waste not!) and got as far as putting the mesh tape on. I used some leftover R-15 Roxul Thermal batts and used a scrap piece of strapping as a support across the front wall.

    Now, I'm starving as I haven't eaten all day and it's time for a double whopper with cheese!

    Thanks for the advice as always Dana.

    Looks like it's about time to crack into another case o' root-beer or something! :)

    You may be pleased to know that I spent most of yesterday correcting insulation faults in my cathedralized ceiling to mitigate against the chronic ice-damming problem, after the person I lent it to a year back returned my insulation blower. I had forgotten to grab the Flir One from the lab to make it easy, but since it would have been a 2-hr round trip to pick it up I did the next-best thing, and was able to spot the bigger voids in the parts I was less certain of using a pistol-grip IR thermometer. In yesterday's bright sun the shingles were measuring 130-135F, and the ceiling temps were warm enough in the less-insulated bays to make it pretty obvious where the biggest voids were. It was registering temps in the low-to mid-90s in the bays that needed it rather than the high 70s/low 80s in the adjacent bays.

    I'm sure there are still other spots that would benefit from packing 0ut, but with the overcast/rain of today and no IR cam to work with, probing with the thermometer wasn't going to cut it, so I took the day off (it is Labor Day, after all. :))

    I can see a little light at the end of the tunnel but I'm not there yet. I need to get the other built-in drawer kneewall cleaned up exactly like I did this one. Then I can finally finish the bathroom. :D Plus I still have to figure out how to fix the window area on the wall that was almost 2" out of plumb without a table saw. That will be....fun. But at least I'm getting some taping practice in on the kneewall drywall first before tackling the bathroom. Gonna make sure I get some nice, flat joints in the bathroom to save me some headache when tiling.

    Ripped out the other built in drawers today. Was rather surprised that I managed to do this side in one day. Got everything done except for the joist insulation because there was one spot with some mold. I sprayed some Concrobium on it so I'm letting that dry before I fill again with insulation. The boss has requested an open shoe rack in that space and will not let me just close it up. Lmfao.

    Opened it up and saw half the insulation on the floor again. Smh.

    More mouse poop but not as much as the other side.

    There was also a paper bag filled with empty coffee cups.

    New insulation in.

    Rockwool R-15 Comfort Batt on the exterior walls.

    Since I had one piece of the R-19 left I used it and filled the other spaces with the Rockwool.

    I think it's time for a dumpster! 15 yard 2 ton should arrive tomorrow. Cost me $450 goddamn it.

    Also on this side there was no blocking at the wall so I installed the 2" XPS foam board that I had leftover and spray foamed as well.

    All taped up and sealed.

    Never celebrate too early! Don't hatch the chickens that haven't been laid yet! Hahahaha.

    I was going to frame the knee wall but then was too feckered so I showered and decided to take the kids to the diner.
