Frequently Asked Questions
What tarp thickness (mil) is best for Halloween props?
Aim for at least 8–10 mil for most yard displays; 12 mil is better if you run animatronics, have sharp edges nearby, or expect sustained wind and rain. Thicker mils resist punctures and last through multiple seasons.
How should I secure a tarp to prevent blowouts?
Use the grommets with bungee cords, ratchet straps, or nylon rope tied to stakes, ground anchors, or heavy-duty sandbags. Space anchors at every grommet when possible and reinforce corners with extra straps or corner bars. For heavy winds add cross-ties and avoid a tight single central anchor that creates stress points.
Can I paint or decorate a polyethylene tarp for a display?
Yes, but choose paints designed to adhere to plastic, like acrylic formulated for outdoor plastics or spray paints labeled for polyethylene. Clean and scuff the tarp lightly, test a small area, and allow full curing. Avoid blocking drainage — add vents or leave perimeter gaps to prevent moisture buildup under covered props.
