Frequently Asked Questions
Are canvas tarps fully waterproof?
Canvas tarps are typically water‑resistant and breathable; they help reduce condensation and can shed light rain, but untreated canvas is not always fully waterproof in prolonged heavy downpours. Many canvas tarps are treated for water repellency and flame resistance, but if full waterproofing is critical, a polyethylene tarp is a more reliable choice.
How thick should a picnic tarp be?
For picnic use and occasional sheltering, 10–16 MIL poly is a good range: 10–12 MIL for lightweight occasional use, 16 MIL for heavier duty and repeated use. Canvas tarps often list an 18 MIL rating in these product lines and are chosen more for durability and flame resistance than pure waterproofing.
How do I prevent a tarp from leaking at the seams or grommets?
Create a slope so water drains away, use reinforced tie points and avoid pooling. For poly tarps, heat-sealed edges hold better than sewn seams. Apply seam tape or a waterproofing sealant around grommets if you need extra protection; choosing tarps with brass or metal grommets and reinforced hems reduces tear and leak risk.
