Quick Answer
Common issues with plow-point tarps in changing weather include tearing, sagging, and water seepage due to the tarp's design and the force of wind and rain.
Tarp Design Limitations
Plow-point tarps are prone to tearing when subjected to strong winds, as the tarp’s material stress can exceed its tensile strength. A rule of thumb is to use tarps with a minimum 200D (denier) rating for harsh weather conditions. However, even with higher-rated tarps, the plow-point design can create a weak point in the fabric.
Securing the Tarp
Improper securing of the tarp can exacerbate the issues mentioned above. To mitigate this, use multiple stakes and guy lines to secure the tarp to the shelter frame. Aim for a 45-degree angle between the tarp and the stakes to minimize sagging. Use a minimum of 6-8 stakes per tarp, spaced 2-3 feet apart, and ensure the stakes are driven at an angle to prevent the tarp from sagging.
Tarp Maintenance and Repair
Regular inspections and maintenance of the tarp can help prevent issues. Check the tarp for signs of wear, such as fraying or punctures, and address them promptly. For tears, use a patching kit specifically designed for polyethylene tarps, and apply a reinforcing tape to the surrounding area. If the tarp is severely damaged, consider replacing it entirely.
