How should the nozzle of a caulking tube be cut for optimal application?

At a 45-degree angle to match the desired bead size for the joint. Straight across the opening. At a right angle to the joint. Cut diagonally to the wall.

Correct Answer:

At a 45-degree angle to match the desired bead size for the joint.

Explanation:

The bead size and control come from how the nozzle is cut. Cutting the nozzle at a 45-degree angle creates a tapered opening that matches the joint width, giving you a controlled, even bead as you smooth it along. This angle helps the caulk lay down smoothly without producing an oversized bead or gaps. Cutting straight across makes the opening too large for precise control, leading to a thicker bead and more cleanup. A right-angle cut tends to produce a thin, uneven line that can skip or pull away from the edge. Cutting diagonally toward the wall misaligns the flow and creates an inconsistent bead. So, a 45-degree cut best balances flow and control for a clean, properly sized bead.
