Kilz or BIN....question about using outdoors.
Hello! In our attached garage we need to first paint a stain killer on the ceiling because there is some discoloration from the pine boards in the attic. Do Kilz or BIN come in interior/exterior formulas, or is it just one product that can be used either inside or outside?
I ask because although it's an attached garage, it gets quite cold and hot in the garage because it's unheated. We live in Indiana, and in the winter we can get sub-zero temperatures.
And can BIN or KILZ be used as a primer, or will I need to apply an actual primer over them? And then when I paint, again....should I use an exterior paint instead of interior?
I trust the people on this forum more than I do the employees at the paint store, so I'm asking here. Thanks!
