In my crowded shop I cover anything I’m using for a finishing bench (including the floor) with a recycled vinyl shower curtain. I use the heavy gauge ones. They fold up easily and store flat. I even use them for drop cloths when painting walls. Its important to me to protect my table saw, but I don’t like to mess up any tables or tools.
I understand the space problem. I have nine power tools that stand on the floor in addition to the hand held tools I use. All of this in a 20×28 attached garage that also allows for overnight parking for the car. Obviously, almost everything is on wheels including large projects like cabinets.
