Why is it important to clean the hole before applying adhesive?

Cleaning the hole before applying adhesive is crucial to ensure a proper adhesive bond. When the surfaces to be bonded are contaminated with dust, debris, or moisture, it can significantly weaken the effectiveness of the adhesive. The presence of these contaminants can create a barrier that prevents the adhesive from making strong contact with the substrate, which is essential for achieving the intended load capacity and structural integrity of the anchor.

A clean hole allows for maximum surface area contact between the adhesive and the base material, facilitating a stronger bond that can support the loads the anchor is designed to bear. This step is fundamental to the performance and reliability of adhesive anchors in construction applications, as compromised bonding can lead to failure under load conditions.
