Frequently Asked Questions
Are these tarps truly waterproof?
Yes — these poly tarps are manufactured to be waterproof and customers commonly report they keep rain out. Proper use and secure tie-downs prevent pooling and reduce the chance of leaks around grommets.
How do I secure a tarp to an RV or canopy without tearing it?
Use reinforced anchor points and even tension. Thread rope through the hem or use bungee cords and cam straps attached to rust-proof grommets. Avoid sharp knots or over-tightening; add edge protection or webbing under high-stress points.
Which thickness should I pick: 5 mil or 10 mil?
Choose 10 mil if you need better tear resistance and longer-term exposure in wind or abrasion-prone areas. Pick 5 mil when packability and light weight matter more, such as for beach trips or occasional shade.
