Diamond Dia-Metallic Hardener is a dry-shake, metallic floor hardener with cleaned and graded, non-oxidizing metallic aggregate in a high-strength cementitious binder. Designed to be incorporated into fresh concrete slabs, it provides a dense, tough surface capable of withstanding the abrasion and impact loading seen by floor slabs of numerous industrial and manufacturing facilities. It has been specially formulated with a non-rusting aggregate for increased abrasion resistance in areas subject to frequent moisture or water exposure. It can also be mixed in a mortar consistency and placed along joints to provide shoulder reinforcement.
