Mudding compound in July will bite you, let it dry or fight it
I keep seeing folks in this group spread a full coat of joint compound on a 95 degree Albuquerque afternoon and sand it the same day, then wonder why it cracks next spring. The hot dry air pulls moisture out so fast the top skins over while the bottom stays wet, so that second pass grabs and tears like peeling tape. Anyone else wait overnight even when the forecast says scorching, or am I just paranoid about my casita walls?
