Extremely hard, abrasion, and impact-resistant, this two-component epoxy is for marine use only. Provides protection against corrosion of metals and erosion and deterioration of concrete and wood above or below the waterline in splash zones. Also can be used as a coating repair of boat hulls and buoys or bridge abutments and on any surface subject to corrosion in salt or freshwater. Not for use in potable water. Used for patching and grouting applications that are not submerged.
