Quick Answer
To minimize water pooling on tarps, use materials with high water-shedding properties, such as silicone-coated fabrics, Mylar, or aluminized Mylar. These materials can be applied to the underside of the tarp or used as a tarp itself. This prevents water from seeping underneath and pooling.
Selecting Water-Shedding Materials
When selecting materials to minimize water pooling on tarps, look for those with a high water-shedding coefficient. Silicone-coated fabrics are an excellent choice, as they have a water-shedding coefficient of 0.97, which means they can shed 97% of water that comes into contact with them. These fabrics can be applied to the underside of a tarp or used as a tarp itself to provide a waterproof layer.
Applying Materials to Tarps
To apply silicone-coated fabrics to a tarp, use a contact cement or a heat-activated adhesive. These adhesives provide a strong bond between the fabric and the tarp, ensuring that water is shed effectively. When applying the fabric, make sure to smooth out any air bubbles or wrinkles that may form, as these can compromise the water-shedding properties of the material.
Tarp Selection and Configuration
When selecting a tarp, choose one with a high water-shedding material, such as Mylar or aluminized Mylar. These materials are designed to shed water and can be used in a variety of configurations, including as a single layer or in a double-layer setup. When configuring the tarp, make sure to leave enough clearance between the tarp and the ground to allow water to run off and prevent pooling. A clearance of 1-2 inches is recommended.
