Drop cloth systems include drop cloths having edge supports extending along two opposite edges of the drop cloths for preventing folding of the opposite edges along which the edge supports extend. Extending between the edge supports is at least one spring strip having the property of being substantially straight when unwound to maintain the drop cloths substantially spread out on the surface area to be protected. Also the spring strips have the property of being windable to permit the drop cloths to be rolled up from one of the opposite edges along which the edge supports extend for easy storage and transportation when not in use.

What is claimed is: 1. A drop cloth system for use in protecting a surface area of a floor or other surface area against splatter during painting or otherwise coating an other surface, comprising a drop cloth and a support assembly for maintaining the drop cloth spread out on the surface area to be protected, the drop cloth having opposite end edges and opposite side edges, and the support assembly comprising stiff edge supports extending along substantially the entire length of two of the opposite edges of the drop cloth for preventing folding of the opposite edges along which the edge supports extend, and at least one spring strip means extending from one of the edge supports to the other edge support, the spring strip means being windable when extended between the edge supports to permit the drop cloth to be rolled up from one of the opposite edges along which the edge supports extend with the spring strip means wound up inside the rolled up drop cloth, and when the rolled up drop cloth is released, the spring strip means unwinds to unroll the drop cloth and the spring strip means is substantially straight when unwound to maintain the drop cloth substantially spread out on the surface area to be protected. 2. The drop cloth system of claim 1 wherein the support assembly is removably connected to the drop cloth to permit the support assembly to be removed for cleaning or replacement of the drop cloth. 3. The drop cloth system of claim 2 wherein opposite ends of the opposite edges along which the edge supports extend include pockets in which opposite ends of the edge supports are removably received. 4. The drop cloth system of claim 2 wherein opposite side edges of a strip of fabric material are secured to one side of the drop cloth in a direction extending from the one edge support to the other edge support provide a channel therebetween in which the spring strip means is received. 5. The drop cloth system of claim 4 wherein one side edge of the strip of fabric material is fixedly attached to the one side of the drop cloth and an other side edge of the strip of fabric material is detachable from the drop cloth for ease of removal of the spring strip means from the channel formed by the strip of fabric material. 6. The drop cloth system of claim 1 wherein opposite ends of the spring strip means are detachably connected to the edge supports. 7. The drop cloth system of claim 1 further comprising straps or ties for maintaining the drop cloth and the spring strip means rolled up together for easy storage and transportation of the drop cloth system when not in use. 8. The drop cloth system of claim 7 wherein the straps or ties include hook-and-loop fasteners for releasably securing the straps or ties around the drop cloth and the spring strip means when rolled up together. 9. The drop cloth system of claim 1 wherein the spring strip means comprises a length of spring steel having a curved cross section. 10. The drop cloth system of claim 1 wherein the spring strip means comprises any one of a coil wire spring, a fiberglass reinforced plastic extrusion, a spring steel or plastic ribbon surrounded by a plastic cover, and spring steel wires or plastic wires embedded or contained in a plastic cover. 11. The drop cloth system of claim 1 wherein the drop cloth is comprised of multiple layers including a moisture-repellent bottom layer, a moisture-absorbent middle layer, and a top layer that allows moisture to pass therethrough for absorption by the middle layer. 12. The drop cloth system of claim 1 wherein the edge supports are rigid strips attached to the opposite edges of the drop cloth along which the edge supports extend. 13. The drop cloth system of claim 1 which includes at least two support assemblies each having respective stiff edge supports extending along the same opposite edges of the drop cloth in end-to-end relation to each other with spacing between adjacent ends of the respective edge supports to permit the drop cloth to be folded between the respective edge supports with any soiled portions of the drop cloth facing each other and then rolled into a tube, and at least one spring strip means extending between each of the respective edge supports that are wound up inside the rolled up drop cloth. 14. A method of protecting a surface area of a floor or other surface area against splatter during painting or otherwise coating an other surface using the drop cloth system of claim 1, comprising the steps of rolling the drop cloth up from one of the opposite edges along which the edge supports extend with the spring strip means wound up inside the rolled up drop cloth, securing the drop cloth in the rolled up condition using straps or ties, placing the rolled up drop cloth system on the surface area to be protected, and releasing the straps or ties to allow the spring strip means to unwind to unroll the drop cloth and the spring strip means is substantially straight when unwound to maintain the drop cloth substantially spread out on the surface area to be protected. 15. The method of claim 14 further comprising the step of moving the drop cloth system from one location to another on the surface area to be protected while the drop cloth is maintained spread out by the edge supports and the unwound spring strip means. 16. The method of claim 14 further comprising the steps of placing a second rolled up drop cloth system on the surface area to be protected, and releasing the straps or ties of the second drop cloth system to allow the spring strip means of the second drop cloth system to unwind to unroll the second drop cloth and the spring strip means is substantially straight when unwound to is maintain the drop cloth substantially spread out on the surface area to be protected. 17. The system of claim 16 further comprising the steps of placing the drop cloth systems on the surface area to be protected with one of the drop cloth systems trailing an other of the drop cloth systems, and moving the trailing drop cloth system ahead of the other drop cloth system during painting or coating a wall or the like as the painting or coating progresses along the wall. 18. The method of claim 16 further comprising the step of placing the drop cloths on top of each other with any soiled portions of the drop cloths facing each other, rolling both drop cloths up together into a tube, and maintaining both drop cloths rolled up together using straps or ties for easy storage and transportation when not in use. 19. The method of claim 14 wherein at least two support assemblies are attached to the drop cloth with the edge supports of each support assembly extending along the same opposite edges of the drop cloth in end-to-end relation to each other with a space or gap between adjacent ends of the edge supports, further comprising the steps of folding the drop cloth between the adjacent ends of the edge supports with any soiled portions of the drop cloth facing each other, rolling the drop cloth up into a tube, and maintaining the drop cloth rolled up using straps or ties for easy storage and transportation when not in use.
