There's a kind of a gap between the asphalt and the garage which causes moisture to accumulate there.
I'd like to seal that gap by making a tar joint:

How should I proceed with this? Is it a complex job? Do I first need to clean the gap as much as possible? What do I need to watch out for? And so on.
Thanks in advance for your kind help.
While the asphalt-base (tar) crack filler would probably work, it is also sticky and messy and will probably end up being ugly against your stucco/plaster wall.
I recommend a self-leveling flexible urethane filler, often sold as "concrete crack filler".
Either way, you will need to sweep out that crack as well as you can, then blast it clean with a stream of water from a hose, then let it dry thoroughly. Take your time when applying so you get a clean, nice looking, even bead.
