Heavy-Duty 18 oz Canvas Tarp (Fire Water Repellent)
Last verified by the Lifetime Picks Editorial Team
Why we picked it
18 oz canvas (vs 7-10 oz consumer tarps)
WHITEDUCK's 18 oz canvas tarp is the heavy-duty tarp that contractors, outdoor outfitters, and ranchers use as a long-term cover where polyethylene blue tarps fail within 6 months. The 18 oz cotton-poly canvas (vs the 7-10 oz canvas of consumer tarps) is rated for prolonged UV exposure and treated with a fire-retardant + water-repellent finish that doesn't wash out the way silicone-spray finishes do. Heavy-duty rustproof brass grommets every 24" support tarp-down tension, and the corners are reinforced with extra layers. r/CampingGear, r/OffGrid, and r/Homestead consistently surface WHITEDUCK canvas as the BIFL alternative to blue tarps — 10+ year service lives are standard. Available in multiple sizes from 6×8 ft to 20×30 ft.
