Brown 12x20 ft Waterproof Poly Tarp — 6 mil Lightweight Cover

Product description

What you get
A brown, double-sided polyethylene tarp manufactured at a 6 mil thickness. The package includes the tarp with a sewn hem containing reinforcing rope and rust-resistant aluminum grommets spaced roughly every three feet for tie-downs.

Materials and build
The tarp is constructed from woven polyethylene cloth bonded between coated plastic layers. Seams are heat sealed to help keep water out, and the edges are folded and stitched with an internal rope for additional perimeter strength. The lightweight film balances packability with basic tear resistance.

Dimensions and hardware
This model is offered in the 12 x 20 foot size described on the label. Grommets are aluminum and treated to resist corrosion; they are positioned at regular intervals around the perimeter to allow bungee cords, rope or straps to secure the cover.

Intended uses
Common applications include sheltering camping gear, acting as a tent footprint, covering boats, cars, grills, furniture and firewood, shading an area, or serving as a temporary roof patch. It’s also suitable as a truck bed liner or general-purpose yard cover where a waterproof barrier is needed.

How to pick a polyethylene tarp
Poly tarps vary by color, dimensions and thickness (measured in mils, where 1 mil = 1/1000 inch). Light retail tarps are often 4–6 mil; heavier-duty commercial tarps run 10–16 mil. Match the mil rating to the task: light tasks and temporary covers can use 4–6 mil, while long-term or abrasive applications benefit from thicker material.

Key construction notes
Most poly tarps use multiple layers with a woven scrim sandwiched between polyethylene sheets for tensile strength. Reinforcements include a sewn hem and an internal perimeter rope to reduce tearing around attachment points.

Safety and care
Keep away from open flames — the material is combustible and will burn. Do not allow children to play unsupervised with the tarp due to suffocation risks. The tarp can be washed, folded for storage and reused as long as care is taken to avoid sharp edges that can puncture the material.

Pros

  • Lightweight and portable
  • Waterproof with sealed seams
  • Rustproof grommets at regular intervals

Cons

  • Thin 6 mil film limits heavy-duty use
  • Can ignite near open flames
  • Not puncture-proof around sharp edges

VerdictThis 6 mil brown polyethylene tarp is a lightweight, economical shelter and cover option. Its woven-and-coated construction with heat-sealed seams and rope in the hem gives decent tear resistance and weather protection for routine outdoor tasks. Rustproof aluminum grommets at 3-foot intervals make fastening straightforward. It’s convenient for camping footprints, quick roof patches, truck bed cove

Reviews

  1. Dennis R. Dietz 5/5

    Good value for smaller dimensions

    Fair price for the size offered. Small-format tarps can be hard to find, so this fills that gap nicely.

  2. J. 5/5

    Does the job

    Waterproof as advertised. Weight feels manageable and the grommets are useful for secure tie-downs.

  3. A real customer 5/5

    A tarp that really performs

    Simple but solid. I jokingly reserve it for extreme scenarios, yet it handles everyday chores like hauling mulch and emergency shelter duties. Reliable, well-made and a tarp I keep ready.

  4. figgenshu 3/5

    Too flimsy for my needs

    Poor quality overall — thinner than expected. Corners have decent support, but the film itself feels weak. Won’t reorder.

  5. Nick K. 4/5

    Fine for light-duty jobs

    Works well if you don’t need heavy-duty strength. Very thin, so avoid areas with sharp corners or rough surfaces.

  6. Asif Moosa 5/5

    Simple and effective

    Does what it’s meant to do — straightforward protection.

  7. sklok 5/5

    Light, bright and great for camping

    Bought the orange 8x8 as a tent footprint for a 94in tent — fits perfectly. Lightweight, durable enough on rough ground and packs down small. Color is a nice bonus.

  8. Zafer Atıcı 1/5

    Size labeling was misleading

    The listing indicated 8x12 meters but I received an 8x12 foot tarp. That mismatch felt deceptive.

  9. Jay Jay 4/5

    Lightweight cover that kept things dry

    Very light and seemed waterproof after one outdoor use. Only time will tell how durable it remains.

  10. jimmy white 5/5

    One year on the coop — still holding up

    After a year protecting my chicken coop this 9x9 poly cover has survived wind, hail and storms without leaking. The 4 mil weight remained intact and the reinforced edges and sealed seams kept everything dry.

  11. Gina D. 5/5

    Durability as described

    Held up well and matched the product description in terms of longevity and performance.
