Abstract
A protective sheet and method for protecting an object is disclosed. The protective sheet or drop cloth is made from a blend comprising ethylene vinyl acetate (EVA) and polyethylene (PE), making it naturally liquid impervious and slip resistant. The protective sheet includes a top side having a raised surface design configured for retaining fluid, and a bottom side that is smoother than the top side for added slip resistance. The method comprises the steps of providing the protective sheet and positioning it over the object, wherein the top side faces away from the object, and the bottom side faces the object and the top side is available for a workman to walk on.
