Red Seal Carpenter Practice Exam

What should be done when forming in order to prevent discoloring of concrete at column corners?

1. Install chamfer strips in the form corners.

2. Ensure tight fitting column corners.

3. Make sure corners have extra release agent.

4. Install a cove strip in the form corners.

The correct answer is: Install chamfer strips in the form corners.

Chamfer strips are used to create smooth, angled edges on concrete surfaces. This prevents sharp corners from forming which can cause cracks and discoloration in the concrete. Options B, C, and D do not address the issue of preventing discoloration specifically at column corners and may not be as effective as using chamfer strips. Tight fitting column corners or extra release agent may not provide enough protection against discoloration, and installing a cove strip may not cover the entire corner area. Chamfer strips are the most appropriate and effective solution for this particular issue.
