Concrete Crack Repair For Floors

[light4darkness]

If it cracked, the slab is too big, or it's near a stress riser, like a sharp corner.

You need to saw a deep cut near the crack and fill it with caulking so it can move, or it will crack again ..

Will work outside as well as inside. It is not effected by temperature.

Looks good. Would it also work for outside concrete driveway? I mean if it can take heat and cold expansions and not crack?
