Frequently Asked Questions
Will a tarp trap moisture and cause mildew on cushions?
A waterproof tarp will block rain but can trap humidity underneath if left sealed. To avoid mildew, use breathable covers for long storage, or periodically lift corners to air cushions and allow drying. Placing foam blocks or slats under cushions to promote airflow also helps.
How should I secure a tarp so it doesn’t blow away in wind?
Use the tarp's metal grommets with bungee cords, ratchet straps or strong rope to attach to anchors, furniture frames or deck rails. Add weights at low points (sandbags or PVC pipe filled with gravel) and avoid over-tightening grommets — consider tarp clips or edge reinforcement if you need extra tie points.
What tarp thickness do I need for fall protection?
For typical leaf season and occasional rain, 8–10 mil offers a good balance of durability and handling. If you face frequent high winds, abrasive edges or want a tarp to last multiple seasons, opt for 20 mil heavy-duty options.
