Wire brushing followed by degreasing, acid etching or grit blasting may be necessary to remove laitance. Ensure concrete is at least 28 days old.

Steel:
All previous surface treatments should be removed taking the surface back to base metal. The base metal should be abraded and preferably shot blasted.
