Quick Answer
To make a tarp shelter more UV resistant, apply a waterproofing treatment, such as silicone spray or wax-based sealant, and consider using a UV-resistant tarp material or a tarp specifically designed for outdoor use. Choose a location with partial shade, if possible, to minimize direct sunlight exposure.
Choosing the Right Tarp
When selecting a tarp for increased UV resistance, opt for materials like nylon, polyester, or silicone-coated polyester. These materials offer improved durability and resistance to sun damage compared to untreated cotton or nylon tarps. Avoid tarps with fabric finishes that can degrade under UV exposure. Look for a tarp with a UV-resistant coating, such as a silicone or polyurethane coating, which can be reapplied as needed.
Waterproofing and Protecting the Tarp
Apply a waterproofing treatment to the tarp to prevent water absorption and subsequent degradation from UV exposure. Use a silicone spray or a wax-based sealant, such as beeswax or paraffin wax, to protect the tarp from water and UV rays. Reapply the treatment as needed, ideally every 6-12 months, depending on usage and environmental conditions. When not in use, store the tarp in a dry, shaded area to minimize exposure to direct sunlight.
Setting Up a UV-Resistant Tarp Shelter
When setting up a tarp shelter, consider partial shade to minimize direct sunlight exposure. Choose a location with nearby trees or a natural canopy to provide some shade. Use a diamond or plow point configuration to create a shelter with minimal UV exposure. When using an A-frame or lean-to configuration, ensure the tarp is pitched at an angle to allow rain to run off and reduce direct sunlight exposure. Finally, secure the tarp with sturdy cordage, such as nylon or polyester rope, and use a reliable knot, such as the bowline or figure-eight, to prevent sagging and UV damage.
