Duralprep AC

Description: A 3 component, pre-proportioned, water based epoxy modified portland cement bonding agent and anti-corrosion coating. Used as a bonding agent for placing fresh concrete to existing concrete and for repair and restoration of concrete surfaces. Contains a unique migratory corrosion inhibitor which protects reinforcement when used as an anti-corrosion coating for steel. Has a long open time, is non flammable, VOC compliant, and does not form a water vapor barrier after cure.

Application: Used as a bonding agent for fresh concrete to existing concrete, concrete repairs, and as an anti-corrosion coating for steel reinforcement. Can be used for exterior or interior, on grade or above grade applications.

Coverage: Coverage rates are approximate, and for estimating purposes only. Surface temperature, porosity, and texture will determine actual material requirements. One full kit of will cover approximately 60 ft². Test the area prior to application to determine effective coverage rates.
As a bonding agent:
60–80 ft²/gal
As an anti-corrosion coating:
60–80 ft²/gal/coat
