Frequently Asked Questions
What tarp thickness do I need for storm protection?
For short-term storm protection, 5 mil tarps are often sufficient and easy to handle. For repeated use, moving furniture, or long-term outdoor storage choose 10 mil or thicker for better tear and puncture resistance.
How should I secure a tarp so grommets don’t tear out?
Use rope or straps through grommets and avoid pulling too tight; distribute tension with bungee cords or webbing loops and attach to multiple anchor points. Reinforce corners with an extra patch or use a tarp with capped reinforced corners and closer grommet spacing (every 18") for heavier loads.
Are these tarps UV resistant and suitable for long-term outdoor use?
Most tarps reviewed list UV-resistant coatings; this helps reduce sun degradation. For genuine long-term outdoor use, choose double-laminated or thicker (10 mil+) tarps with heat-sealed seams and reinforced corners to minimize wear from sun and wind.
