Vetorep CR526

Cut back all damaged and weak concrete to reach sound concrete and/or until a minimum depth of at least 10 mm is reached. 

Grit blast corroded steel reinforcement to remove all rust traces. In case of significant loss in the steel reinforcement cross-section, replace the steel entirely. Remove all concrete forms around the exposed steel reinforcements by a thickness of 25 mm. Saw cut the perimeters of the repair area to a minimum depth of 10 mm. Clean the prepared area thoroughly using a brush and/or compressed air. 

Prime all grit blasted steel reinforcements within 2 to 4 hours with one or two coats of Vetoprime CP436. Soak the areas to be repaired with clean water before applying the repair mortar. Remove all excess water before applying one coat of acrylic bonding agent Vetobond AB432. Allow Vetobond AB432 to become tacky before applying the repair mortar. 

Use a mechanically powered mixer or a drill fitted with a suitable paddle to ensure proper mixing. Add 2.8 to 3 liters of clean water to a clean container. Add the powder slowly to the water while mixing continuously with a low-speed mixer/drill (400 - 600 rpm). Continue mixing for 5 minutes until a uniform consistency is achieved. 

Apply Vetorep CR526 by trowel or hand. Fully compact the mixed mortar into the substrate by firm pressure to ensure good adhesion with the steel reinforcements and the substrate. Finish and level the surface initially by a wooden or plastic float. Carry out the final finish using a steel float. 

Vetorep CR526 is a cementitious-based material, so you can cure it similarly to concrete. Curing can be done using Vetobond AB432 or by continuous watering & covering with polyethylene sheets.

Clean all tools with freshwater immediately after application. Clean hardened materials mechanically.
