Frequently Asked Questions
How many tie-downs and grommets do I need for a patio set?
Aim for tie points every 18–24 inches along the tarp edge in exposed areas; closer spacing (18") is safer in high-wind zones. Use at least 6–8 tie-downs on a medium-sized set and add more for larger or taller items. Reinforce corners and any spot where straps pass over sharp frames.
Can I leave a tarp on furniture all winter?
Yes, if the tarp is heavy-duty (10–20 mil) with reinforced edges and properly anchored. Leave some airflow to prevent trapped moisture and mildew — tuck vents or lift edges slightly when conditions are calm. Replace or repair any torn areas promptly to maintain protection.
What should I keep in a tarp repair kit?
Include adhesive polyethylene or vinyl patches, a roll of tarp-reinforcement tape, extra metal grommets and a grommet-setting tool, and some heavy-duty outdoor-rated zip ties or straps. These let you fix small tears and rebuild tie points without replacing the whole tarp.
