Frequently Asked Questions
How thick should my tarp be for spring storms?
For temporary storm protection a 12 mil tarp is usually sufficient. If you expect repeated use, heavy abrasion, or prolonged UV exposure, a 16 mil tarp offers noticeably better resistance to tears and punctures.
How do I secure a tarp so it doesn’t rip or flap in wind?
Use the grommets and reinforced edges to anchor the tarp at several points with straps, ropes or ratchet tie-downs. Keep tension even, avoid sharp tie points, and add edge protection (a wood strip or foam) where ropes contact the tarp to reduce chafing.
Can I leave these tarps outside year-round?
Polyethylene tarps can be left outside but UV and weather will degrade them over time. If you plan year-round exposure, choose thicker material (16 mil), inspect frequently for thin spots, and replace at the first sign of significant wear.
