(i) On the roof, between the (std. asphalt residential) shingles and the aluminum siding to fill a 3/4" gap that has creaped away from the last caulking there.
(ii) Between the new walls and ceiling I just installed in the basement shower. It hasn't been used in years and probably won't for years to come. So there will be time to dry, but still. Its just a small square unit, and the wall and ceiling panels are above the unit. Some splash will make its way to the joints between the panels and the unit (maybe 6' high) and the rest of the joints are above that and is just going to be humid.
Just wondering if its too soft? ie need another type for these jobs? eg exchange for Latex?
