Frequently Asked Questions
Will these tarps trap heat under the cover?
These tarps are designed to balance waterproofing with breathability—the 220 GSM mesh/polyethylene construction allows some airflow and many users report reduced heat buildup vs solid plastic tarps. For hot climates, choose lighter colors and ensure gaps for ventilation.
Can I cut or trim a tarp to size?
Yes, you can trim to fit, but cut edges may fray unless finished. If possible, order a custom size from the manufacturer or reinforce cut edges with seam tape to maintain durability.
How do I remove the initial factory smell?
Air the tarp outside for 24–48 hours before use; sunlight and fresh air typically dissipate any packaging or manufacturing odors quickly.
