The EA Primer/Slurry bond coat serves an important purpose in the concrete repair process. Its primary function is to enhance the bond strength between the damaged substrate and the Elephant Armor® repair material. This is a detailed explanation of its purpose:

Bond Enhancement

The EA Primer/Slurry bond coat acts as a bonding agent between the existing substrate and the repair material. By applying the slurry coat, you create a strong adhesive layer that helps establish a durable bond between the two surfaces. This bond is crucial for the long-term performance and effectiveness of the repair.

Surface Preparation

The slurry coat also helps in preparing the substrate for the application of Elephant Armor® repair material. It ensures that the surface is clean, free of contaminants, and properly hydrated. When applying the slurry coat, remove any dust, debris, and other impurities that could hinder the bond between the repair material and the substrate.

Consistency and Workability

The slurry coat, when mixed 2 parts Elephant Armor® to 1 part EA Primer, provides a consistency similar to pancake batter. This consistency allows for easy application on the damaged substrate, ensuring uniform coverage and proper adhesion of the Elephant Armor® repair material.

Moisture Retention

It is crucial that the slurry coat does not fully dry before placing the Elephant Armor®. The wet and tacky nature of the slurry coat helps retain moisture in the substrate, preventing premature drying and ensuring a favorable environment for the bond to develop.

The EA Primer/Slurry bond coat plays a vital role in promoting a strong and durable bond between the substrate and the Elephant Armor® repair material. It improves the adherence of the repair material, enhances the overall performance of the repair, and contributes to the longevity of the repaired concrete structure.
