Trim-A-Slab Magic Crack Filler is a fine powder that fills hairline cracks in concrete, a complement to Trim-A-Slab to repair your driveway and sidewalk.
Brush into even the tiniest of cracks, and they disappear. To activate, simply mist with water. Magic Crack Filler does not re-attach cracked slabs, but it does make cracks practically invisible!
Trim-A-Slab Magic Crack Filler has no shelf life, unlike the caulk-like products that are generally suggested for crack repair.
To use Magic Crack Filler, simply brush into the crack until it is full, then mist with water. That’s it!
