What are the steps to apply spray knockdown texture to a wall?

To apply spray knockdown texture to a wall, first prepare the surface by cleaning and priming it. Then, mix the texture material according to the manufacturer's instructions. Next, load the texture material into a hopper gun and adjust the nozzle to achieve the desired pattern. Spray the texture onto the wall in a consistent and even manner. After spraying, use a knockdown knife to flatten the texture slightly, creating a textured finish. Allow the texture to dry completely before painting or finishing the wall.
