How to Reinforce Tarp Grommets for RV & Boat Travel (2026 How-To)
If you travel with a tarp on an RV or boat, failing grommets are one of the most common wear points — salt spray, constant vibration and gusting wind quickly turn a small hole into a large tear. This guide shows proven techniques and tarps that reduce grommet failure: choose the right material, add mechanical reinforcement, and use vibration- and corrosion-resistant hardware. I tested and compared tarps based on material thickness, hem construction, grommet type and spacing, and real customer feedback about durability and fit to recommend practical, travel-ready options.
Quick Answer
Reinforce tarp grommets by choosing a heavy-duty tarp with reinforced hems and rust-proof grommets, then add backing plates or rubber washers where you tie down. The top pick, Xpose Safety Heavy Duty Poly Tarp (20' x 35'), combines 10 mil polyethylene and edge grommets to reduce tear and abrasion under travel conditions.

Frequently Asked Questions
How do I stop grommets tearing during RV or boat travel?
Reduce concentrated load by adding backing plates or large stainless washers on the tarp’s underside, use wide webbing straps instead of thin rope, and distribute tie-downs closer together. Consider sacrificial vinyl or nylon patches under high-stress grommets and avoid overtightening so the tarp can flex without ripping.
Do I need special hardware for saltwater use?
Yes. Use stainless steel or brass washers and hardware and silicone or rubber grommet washers to isolate metal from salt. Rinse tarps and hardware with fresh water after exposure and dry fully before storage to slow corrosion and salt crystallization that weaken grommets.
Will a thicker tarp alone prevent grommet failure?
Thicker material helps, but it’s not enough by itself. Combine a sturdy tarp with reinforced hems, closer grommet spacing, and external reinforcement (backing plates, rubber washers, rope-reinforced hems) to handle vibration and wind. Regular inspection and rotating tie-down points also prevent early failure.
