Vetobond EB430

Clean all surfaces and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits, or algae. Roughen the surfaces, remove any laitance and expose aggregate by light scabbling or grit-blasting. Remove oil and grease deposits by steam cleaning, detergent scrubbing, or the use of a proprietary degreaser. A pull-off test should then assess the effectiveness of decontamination and the soundness of the substrate. Any steel reinforcement and formwork should be prepared, cut to size and shape, and made ready for assembly before mixing commences.

Ensure mixing Vetobond EB430 thoroughly. Stire the ‘hardener’ and ‘base’ components separately before mixing to disperse any settlement. Pour the entire content of the ‘hardener’ tin into the ‘base’ tin. Mix the two materials thoroughly using a suitable slow-speed drill and mixing paddle for 2 minutes until obtaining a fully uniform color. Scrap the sides of the tin, and continue mixing for a further 1 minute. Slowly add the Reducer part and mix for 3 minutes.

To facilitate mixing and application at temperatures below 22ºC, the separate components should be warmed in hot water up to a maximum temperature of 25ºC before beginning to mix. If heated to 25ºC, the subsequently mixed material will need to be used more speedily as the pot-life will be reduced to 4 hours. Alternatively, Store the material in an environment heated to 22ºC and remove it immediately before use.

Apply Vetobond EB430 as soon as the mixing process completes. Brush Vetobond EB430 or spray it to the prepared surfaces. The new concrete or screed may be applied to the coated substrate up to 24 hours after application at 22ºC or up to 12 hours at 30ºC, or between 8 to 10 hours at 35ºC. However, leave the coated substrate for one hour before placing the new concrete or screed. Take care to achieve an unbroken coating, where Vetobond EB430 is used as part of a repair system to form a substrate/repair barrier. Apply one coat and allow to gel. Apply a second coat and use it as the bonding coat. In some situations (e.g., sprayed concrete repairs), it may be advantageous to scatter dust-free sharp sand over this coat and leave it to harden. As soon as the Vetobond EB430 has been applied, any required steel reinforcement and/or formwork should be elected and fixed securely in place.

Remove Vetobond EB430 from tools, equipment, and mixers with Vetonit Solvent 1 immediately after use.

Hardened material can only be removed mechanically.
