Frequently Asked Questions
Will these tarps block damaging UV light from the autumn sun?
Yes — these Guard Shield tarps are advertised as UV resistant and their 10‑mil woven/coated polyethylene construction blocks a large portion of UV exposure compared with thin plastic sheeting. For plants that need some light, choose lighter colors or position the tarp to allow diffuse light while still blocking direct sun.
How should I secure a tarp so grommets don’t rip out?
Spread load across several anchor points, use marine‑grade bungee cords or straps rather than a single tight knot, and add washers or grommet reinforcements where tension is concentrated. For long runs consider sewing or taping a strip of reinforcing fabric behind the grommet or using a tarp repair patch kit.
Can these tarps be left outside all season?
They’re built for outdoor use and hold up well for seasonal protection, but long‑term exposure to UV and weather will eventually degrade polyethylene. For best longevity remove tarps in severe storms, periodically check seams and grommets, and store folded in a dry spot when not needed.
