Frequently Asked Questions
What does 6 mil or 7 mil mean and which is better for picnics?
Mil refers to thickness (thousandths of an inch). 6 mil is very lightweight and easy to pack—good for occasional picnics and ground covers. 7 mil (or 70 GSM cross-laminated) is a bit thicker and offers better tear and weather resistance for frequent use or shelters.
Are these tarps waterproof and UV-resistant?
Most models here advertise waterproofing and UV resistance, but real-world reports vary—cross-laminated Queen of Tarps models have stronger waterproof and UV performance, while some lightweight woven polyethylene tarps can show leaks at folds or wear faster in sun.
How should I secure a tarp at the park or campsite?
Use rustproof grommets with paracord, bungee cords, or stakes. Tie to trees or use tent stakes at each grommet for wind. A rope-in hem or reinforced corners reduce tear risk when tensioning the tarp.
Will a tarp this size fit my picnic blanket needs?
Check dimensions carefully before buying—20x20 and 20x30 tarps give ample coverage for families and shade, while 10x12 or 16x20 suit small groups or as tent footprints. Customers often note size mismatches, so verify the exact feet measurement against your group size.
