Tarp vs. Dropcloth — What's the Difference?

A tarp, short for tarpaulin, is typically made from heavy-duty, waterproof materials such as canvas or polyester coated with polyurethane. It is used for protective purposes in outdoor settings, such as covering vehicles, boats, or as a shelter from rain and wind. Dropcloths, on the other hand, are primarily used indoors during painting or remodeling activities to protect floors and furniture from paint spills, dust, and debris. They are often made from canvas, plastic, or cloth.

Tarps are designed to be durable and resistant to various weather conditions, including heavy rain, strong winds, and prolonged sun exposure. They are usually equipped with grommets at the edges for securing with ropes. Dropcloths, whereas, are lighter and designed for temporary use; they lack features like grommets as their main function is to lie flat and cover surfaces.

In terms of texture and flexibility, tarps are generally thicker and less flexible compared to the materials used for dropcloths. This ruggedness helps tarps withstand harsh conditions, whereas dropcloths are softer and more pliable, making them easier to spread over interior surfaces and furniture.

While tarps are almost always waterproof or at least highly water-resistant, dropcloths may not be. Waterproof dropcloths are available but are more the exception than the rule, primarily because indoor protection typically does not require waterproofing.

Both tarps and dropcloths serve the primary function of protection; however, the nature of what they protect and how they are used fundamentally differs based on the environment and the specific needs of the user. Outdoor versus indoor usage dictates much of their design and material composition differences.
