Frequently Asked Questions
What does 'mil' mean and how thick should my tarp be?
Mil measures the tarp's thickness in thousandths of an inch. For short-term use or light-duty projects, 3–6 mil is adequate. For regular outdoor protection choose 8–12 mil; for long-term, heavy-duty tasks like roofing or winter storage pick 16–20 mil.
How important is grommet spacing?
Grommet spacing determines how securely you can tie a tarp down. Closer spacing (12–18 inches) provides more tie points and reduces flapping; wider spacing (24–36 inches) is fine for lighter applications but makes it harder to create a tight, wind-resistant hold.
Can a tarp with 100% virgin polyethylene be left outside year-round?
Yes—tarps made from 100% virgin polyethylene are formulated for outdoor use and resist UV, water and rot, but longevity depends on thickness and exposure. Thicker, reinforced tarps last longer under constant sun and wind; still, periodic inspection and re-tensioning will extend lifespan.
