Keten Tarps Heavy Duty 18×24
The Keten tarp is a 16 mil, extra-thick outdoor cover with tear and fade resistance. It features reinforced corners and heat-sealed edges for durability. Grommets are spaced every 23 inches to simplify anchoring in windy conditions. This tarp is UV-blocking and waterproof, designed for year-round use in sun, rain, snow, or wind. Best for: long-term exterior protection on roofs, boats, or patios. Caution: higher thickness means more stiffness, which can complicate packing in tight spaces.
CARTMAN Finished Size 18×24 20 Mil
This CARTMAN tarp is finished at the exact 18×24 ft size with a 20 mil thickness for maximum durability. Made from virgin polyethylene, it resists tearing, ripping, and rotting. The product emphasizes a dense 16×16 weave and reinforced edges, making it well-suited for demanding outdoor tasks like protecting equipment or sheltering construction zones. Best for: applications needing robust protection and frequent exposure to outdoor elements. Limitation: heavier and bulkier than thinner tarps, requiring stronger anchoring in windy sites.
CARTMAN Finished Size 18×24 12 Mil
This 12 mil CARTMAN tarp offers a lighter, budget-friendly option without sacrificing basic durability. It uses virgin polyethylene and includes reinforced edges and UV treatment for sun exposure. Grommets are placed every 18 inches, aiding quick installation. Best for: light-to-moderate protection tasks where cost and portability matter. Limitation: less heavy-duty than 16–20 mil alternatives, so wind-prone environments may require additional ties.

Buying Guide
How thick should your tarp be? Thicker tarps (14–20 mil) offer better tear resistance and wind stability, but are heavier and less flexible. What about grommets and edging? Reinforced corners and closer grommet spacing improve resistance to tearing and stretch in wind. Which finish size matters? Ensure the tarp finish matches your exact 18×24 ft requirements to avoid gaps and improper coverage. Is UV resistance important? For sun-exposed setups, UV-blocking materials extend life and reduce material degradation. Do you need virgin polyethylene? Virgin resin provides consistent performance and fewer defects than recycled plastics. Finally, consider storage and handling: thicker tarps are bulkier but typically provide longer service life in harsh environments.
