Large Waterproof Tarp 50ft x 70ft - Heavy Duty 5 Mil Protection

In this review the Large Waterproof Tarp 50' x 70' is judged as a practical, heavy-duty cover for outdoor gear and temporary shelter needs; the single biggest reason to buy is straightforward protection - it keeps items dry and resists UV and mildew while remaining light enough to handle. The reviewer found it most useful where a large, inexpensive waterproof sheet is needed for boats, canopy tents, RVs or pooled equipment, and notes that the extra-thick 5 mil material is the defining feature that sets expectations for durability and value.

Key Features

• Extra thick 5 mil construction: Provides a balance of tear resistance and manageable weight for moving and securing large covers.
• Waterproof and mildew-proof material: Keeps stored items, tents and vehicles protected from heavy rain and snow without trapping moisture long term.
• UV protection: Helps limit sun damage to the tarp and whatever is underneath during extended outdoor use.
• Reinforced hem with rope: Adds tear resistance along edges so tie-down points hold better under tension.
• Rust-proof grommets every 36 in: Allow secure anchoring at regular intervals for stable coverage over large objects.
• Lightweight for size: Easier to manoeuvre for one or two people compared with heavier canvas alternatives.

Who It's For

This tarp works well for homeowners and hobbyists who need a large, economical cover to protect stored goods, woodpiles, grills, or to provide an emergency roof patch. It is also suited to boat and RV owners who want a temporary, full-coverage solution for off-season storage or storm protection.

Those seeking a premium, industrial-grade tarp for constant heavy-duty work or for repeated high-wind, abrasive conditions should look for thicker marketplace options or reinforced commercial tarps; similarly, if breathability or long-term UV warranties are crucial, a specialized cover may be preferable.

Pros & Cons

Pros

• Good overall protection from rain and snow thanks to waterproof and UV-resistant fabric.
• Large 50 ft x 70 ft dimensions cover boats, canopy tents or multiple items at once.
• Reinforced hems with rope and rust-proof grommets give reliable tie-down points.
• Light enough for two people to handle despite its size, making deployment practical.

Cons

• Some users report mixed durability; occasional ripping under extreme stress suggests limitations for very abrasive or high-load use.
• At 5 mil thickness it is not as heavy as canvas or commercial reinforced tarps for continuous industrial exposure.

Our Verdict

The Large Waterproof Tarp 50' x 70' is a solid value for anyone needing extensive, short- to medium-term protection from rain, sun and snow; its 5 mil material, reinforced hems and regularly spaced grommets make it a practical choice for covering boats, RVs, canopy tents and stored equipment. Buyers who want the most heavy-duty, long-term industrial tarp should consider thicker specialized options, but for general-purpose outdoor covering this tarp delivers protection and convenience at a sensible price.

Frequently Asked Questions

Is this tarp suitable for covering a boat?
Yes; the large size and waterproof, UV-resistant material make it suitable for covering small to mid-size boats, though very heavy winds may require extra secure tie-downs.

How often are the grommets spaced?
Grommets are placed every 36 in along the hem to provide regular anchoring points for ropes and bungee cords.

Can it be used as a camping groundsheet?
Yes, it can serve as a groundsheet or temporary shelter floor; it is lightweight enough for handling but not designed as a breathable long-term camping floor for extended wet conditions.
