Use a Cardboard Shield for Overspray Control

What happens here

The video demonstrates how to effectively control overspray while spray painting, particularly when working near corners or edges. The painter holds a flat piece of cardboard, referred to as a "cardboard shield," firmly against the surface that should not be painted. As the spray gun applies paint to the intended area (a white block wall that is being painted yellow), the shield acts as a barrier, creating a sharp, clean line and preventing the paint from spreading to the adjacent finished yellow section. The technique involves moving the shield along with the spray gun, maintaining consistent pressure against the protected surface.

Goal: Achieve a clean paint edge and prevent overspray when spray painting.
