The tack strips used to secure carpeting to a concrete slab are equipped with small, hardened nails that penetrate and grip the concrete. These small nails must be pried out as the tack strip is removed, and they typically chip out the concrete gripped by them. Whether you are repairing these blemishes for a new floor coating or simply want to improve the appearance of the concrete floor, patching holes left behind by the removal of tack strips is a simple procedure that quickly restores the floor's smooth surface.

Tips and warnings

  • Epoxy-based concrete-repair products are preferable to cement-based patching compounds because they offer better adhesion and do not decompose or detach over time.
