Canvas vs Poly vs PVC Tarps: Best Uses & Picks (2026)
Choosing between canvas, poly and PVC tarps comes down to a few trade-offs: how tough you need the cover to be, whether breathability matters, and how much sun exposure or cold you face. This guide compares the three tarp materials across durability, breathability, UV resistance and ideal seasonal uses, then tests three common Trademark Supplies poly tarps so you can see how a popular poly option stacks up. Products were chosen from real market entries based on construction features (thickness, grommets, reinforced hems) and customer feedback about quality, value and durability.
Quick Answer
For most buyers who want durable, waterproof seasonal protection the Trademark Supplies Large Waterproof Tarp - Heavy Duty 20 Mil Thick Poly Tarpaulin (ASIN B07FWKCRX3) is the best pick for overall value and weather protection.

Check Latest Price on AmazonWhich One Should You Choose?
If you need a reliable, affordable waterproof tarp for general tasks — including covering equipment, vehicles or emergency roof work — choose the Trademark Supplies 20 Mil Heavy-Duty Poly Tarp (B07FWKCRX3) for the best balance of protection, value and ease of use. If you need very large coverage for events or ground protection and prefer lighter handling, pick the 40' x 60' or 30' x 70' 5 mil options (B07D9TG147 or B07JK8CM79), but accept thinner material and more careful fastening. If long-term UV exposure and maximum tear resistance matter more than weight, consider moving up to PVC-style tarps (not in this reviews list) or the thickest poly you can find.
Best for Specific Scenarios
- Temporary roof or storm cover: Trademark Supplies 20 Mil Poly (B07FWKCRX3) because its heavier 20 mil thickness and reinforced hem give better short-term tear resistance and waterproofing.
- Groundsheet for events or landscaping: Trademark Supplies 40' x 60' or 30' x 70' 5 mil tarps (B07D9TG147 / B07JK8CM79) because the huge footprint covers more area and is easier to deploy.
- Long-term outdoor storage in sun: Opt for PVC or the thickest poly available (choose premium PVC options) because they offer superior UV resistance and longer lifespan versus thin poly or untreated canvas.
Frequently Asked Questions
Are poly tarps waterproof?
Yes—polyethylene tarps are manufactured to be waterproof and mildew-resistant. Waterproofing is excellent for rain and snow, but seam strength and grommet reinforcement determine how long they stay leak-free under heavy wind and repeated use.
When should I choose canvas over poly?
Choose canvas when breathability and abrasion resistance matter, such as for storing leather, machinery or items that can't tolerate trapped moisture. Canvas is heavier and less waterproof, so it’s better for drier climates or covered storage.
How much does thickness (mil) matter?
Thickness (measured in mils) strongly affects tear resistance and durability. Thicker poly (15–20 mil) lasts longer under wind and abrasion; 5 mil works for one-off or light-duty uses but can rip more easily. Match mil to expected stress and frequency of use.
