ACI Adhesive Anchor Installer Certification Practice Exam

For an overhead installation, what should be done if the adhesive is not qualified for overhead use?

1. The installation should be done with caution

2. Complete the installation as instructed

3. Choose a different adhesive

4. Abandon the installation

The correct answer is: Complete the installation as instructed

In the context of adhesive anchor installation, choosing an adhesive that is specifically qualified for the intended application, such as overhead installation, is crucial to ensuring the effectiveness and safety of the bond. If the adhesive is not qualified for overhead use, it would not be appropriate to complete the installation as instructed using that adhesive. The recommended action involves selecting an adhesive that is formulated and approved for overhead applications. Such adhesives usually have specific properties that allow them to maintain their bond in a gravity-defying scenario, which is essential for the safety and integrity of the installation. Choosing a different adhesive allows the installer to ensure compliance with safety standards and performance expectations. Using a non-qualified adhesive in an overhead installation could lead to failure in the bond due to factors like gravity, which can cause the adhesive to sag or not set properly as intended. Therefore, prioritizing the use of the correct adhesive tailored for the job significantly reduces the risk of installation failure and potential safety hazards.
