Vetocrete CC806

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

Grit-blast corroded steel reinforcements 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 (until a thickness of 25 mm is reached). Then saw-cut the perimeters of the repair area to a minimum depth of 10 mm. Clean the prepared area thoroughly with a brush and/or compressed air. 

For new construction, prepare a steel reinforcement and pump the material until the desired thickness is reached. Use a suitable high-to-medium pressure pneumatic pump.

Before using Vetocrete CC806, prime grit blasted steel reinforcements within 2 to 4 hours of the application while doing repair work. You can do this by applying 1 or 2 coats of Vetoprime CP436 (a corrosion inhibitor for steel reinforcement). 

Soak the areas being repaired with clean water before applying the repair mortar. Remove all excess water before the application begins. (Note: apply one coat of acrylic bonding agent Vetobond AB432). 

Allow Vetobond AB432 to become tacky before applying the repair mortar (Vetocrete CC806). For new construction, clean the substrate and steel reinforcement from dirt, rust, or anti-adhering materials.

To ensure proper mixing, use a mechanically-powered mixer or a drill fitted with a suitable paddle. Add 5.5 - 6.75 liters of clean water to a clean container. Then slowly add the powder 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 obtained. For large quantities, use a large mechanical drum mixer. 

Add water to fill 2/3 of the mixer capacity. While mixing, add the powder and then gradually add the rest of the water until the desired consistency is reached.

Apply Vetocrete CC806 pneumatically using a suitable pump to ensure good adhesion with the steel reinforcements & the substrate.

 Initially, finish & level the surface using an aluminum rod or steel trowel. Use a steel float for the final finishing. Finish the applied material surface within two hours, as the material sets faster than regular concrete and mortar.

Vetocrete CC806 is a cementitious-based material; therefore, cure it like you cure concrete by continuous watering and covering the surface with polyethylene sheets.

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

Apply Vetocrete CC806 in a single application for sections up to 20 mm in thickness for overhead applications.
