Frequently Asked Questions
What mil thickness do I need to protect my grill long-term?
For long-term, multi-season protection choose at least 10 mil; 20 mil is preferable if your grill is exposed to heavy weather, falling debris, or frequent abrasion. Thicker tarps resist punctures and hold up better where wind or contact points put stress on material.
How should I measure my furniture to pick the right tarp size?
Measure the full height, width and length of the item including wheels or cover. Add 6–12 inches per side to allow for tie-downs and overlap. If the furniture has irregular shapes, aim for extra grommet spacing so you can secure it snugly.
How do I secure a tarp so it doesn't tear at the corners?
Use reinforced corners and distribute load across multiple grommets. Pad corners with a scrap of fabric or foam between the rope and tarp, use wide straps or flat webbing rather than thin rope, and avoid overtightening which can concentrate stress and cause tears.
