Frequently Asked Questions
What "mil" thickness do I need for camping vs equipment covers?
For camping and short-term use, 5–10 mil tarps are usually sufficient and easy to pack. For equipment, vehicles, decks or long-term outdoor storage, choose 10–20 mil (or higher) for better abrasion and puncture resistance.
How should grommets be spaced and what material is best?
Grommets spaced every 36" are common and work for most uses; closer spacing improves security. Rust-proof or aluminum grommets are fine, but stainless steel is best for corrosive/high-humidity environments. Reinforced hems or rope in the hem reduce tear risk at grommet points.
Can I leave a tarp up year-round?
You can, but choose a UV-stabilized, mildew-resistant tarp with heavier mil (10–20+) and reinforced hems. Regularly check for wear and retension tie-downs after storms to prevent wind damage; even premium tarps will degrade over several seasons in direct sun.
