Painting in commercial, residential, and retail environments requires extreme care to avoid paint being deposited where it is not required. Drop cloths are commonly used to protect a floor or furniture during the painting process. However, these are generally simply plastic sheets to provide a barrier to the liquid paint and nothing more. Accordingly, it would be advantageous to provide a drop sheet or tarp that supports a liquid material drying process such as by dehydration, coagulate, etc. or form solid materials thereby reducing the instances of subsequent paint transfer from the drop sheet or tarp directly or indirectly to other surfaces and/or objects. It would also be advantageous to drop sheet or tarp that provides a non-slip surface which prevents the drop sheet from sliding around and remains well in place without additional weights, tape, etc.
