Spray Paint Wall Edge with Cardboard Shield

What happens here

Begin by preparing your spray painting equipment, ensuring your paint spray gun is loaded with the desired wall paint and connected to an air compressor, if applicable. Take a long, sturdy piece of cardboard. Position the cardboard firmly against the surface adjacent to the wall you intend to paint, such as the ground or floor, ensuring it is perfectly straight and flush with the desired paint line. While holding the cardboard in place with one hand, use the paint spray gun to apply an even coat of paint along the wall edge, using the cardboard as a protective shield to prevent overspray onto the adjacent surface. Move the cardboard along the wall as you spray, maintaining a consistent distance and angle to achieve a uniform and sharp paint line. The video shows this technique being applied to a textured white wall, creating a clean boundary with the ground below.

Goal: Create a clean, straight paint line along the bottom edge of a wall using a cardboard shield.
