When applying CBA™ (Concrete Bonding Adhesive), following proper application instructions for optimal results is important. Here are the general application guidelines:
- Surface Preparation: Ensure the surface is clean and properly prepared, free from loose materials. Remove any dirt, dust, oil, grease, or contaminants hindering adhesion.
- Mixing: Follow the manufacturer’s instructions for mixing CBA™. Use the recommended mixing ratios and ensure thorough mixing to achieve a uniform consistency.
- Application Method: CBA™ can be applied using a brush, roller, or trowel, depending on the project’s specific requirements. Choose the most suitable method for the surface and desired application thickness.
- Apply Evenly: Apply CBA™ evenly onto the prepared surface, ensuring complete coverage. Avoid leaving any gaps or thin spots that may compromise the bonding strength.
- Working Time: Take into account the working time of CBA™. Apply the adhesive within the recommended time frame to ensure proper bonding. Avoid applying CBA™ beyond its operating time, as it may affect adhesion.
- Bonding Fresh Concrete: When bonding fresh concrete to hardened concrete or other surfaces, apply CBA™ to the fresh and receiving surfaces. Ensure that both surfaces are coated adequately before joining them together.
- Curing: Follow the curing instructions provided by the manufacturer. Allow sufficient curing time for the adhesive to strengthen before subjecting it to load or further construction activities.
