I have a very thin hairline crack in my conrete slab, right in the middle
of the garage doorway. It is barely visible and is so thin I can't even
feel it with my fingers. Unfortunately, water still finds it's way into the
crack on the outside of the garage door and seeps along the crack to the
inside of the garage. So, I would like to seal up the crack before it turns
into a bigger issue.
Any recommendations?
Most crack sealers seem to be made for larger cracks, so I'm not sure they
would even get down into my hairline crack.
Thanks,
See if you can rent one of these.

Use it to clean out and widen the crack. Then fill the crack with
grout.
