Any one use Quikrete Concrete Repair tube caulk for caulking non-smooth concrete such as patio, walks etc? I like the way it has a rough finish like the rough concrete but is horrible to work with. It has a pebble like substance in the caulk thus giving it a concrete finish look. But continually clogs up the tube end. Only way to avoid seems to be to cut the opening > 3/8" which then is a little bigger than I'd like for the cracks. Anyone have different experience?
