Unlock Trigger and Clear Nozzle

What happens here

The DAP Knock Down spray can is equipped with a trigger lock mechanism. Locate this trigger lock, often a small red or black tab, and pull it out or disengage it to allow the trigger to be pressed. Before applying the product to your actual patch, perform a test spray off to the side on a scrap piece of material or a protected area. The first pull of the trigger will expel liquid from the internal tube that prevents clogging, ensuring a consistent and even spray when you begin working on your intended surface.

Goal: Enable spraying and clear the nozzle for consistent application
