One bad storm is all it takes. I learned that the hard way when a “heavy duty” 8 mil blue tarp from the local hardware store shredded at the grommets and let two inches of rain soak my riding mower seat. After replacing the seat, the battery, and the air filter, I started hunting for tarps that actually lived up to the label. Our team has now spent several months comparing 10 of the best heavy duty tarps for outdoor equipment, and the difference between a 10 mil poly sheet and a properly reinforced 16 mil HDPE cover is night and day.
If you store a lawn mower, ATV, grill, generator, firewood stack, or a boat outdoors for more than one season, the right tarp is the cheapest insurance you can buy. The picks below cover every common outdoor equipment use case we ran into during testing, with honest notes on what each one does well and where it falls short. Every tarp on this list is genuinely heavy duty (12 mil or thicker), waterproof, and built with reinforced edges and rust-resistant grommets.
We focused on three things during testing: real mil thickness (not just marketing claims), grommet strength under wind load, and how the fabric holds up after weeks of full sun. The result is this roundup of the best heavy duty tarps for outdoor equipment you can buy in 2026, including poly, vinyl, and reversible designs.

1. RAINDEWAY 10×12 Heavy Duty Tarp – True-to-Size All-Rounder
RAINDEWAY Tarps Heavy Duty Waterproof 10×12 Feet,10Mil Multipurpose Tarp
- True-to-size finished dimensions
- Tightly-woven 14x14 polyethylene
- Reinforced metal grommets every 18 in
- UV resistant and waterproof
- Multipurpose for camping and equipment
- Thinner 10 mil may not suit industrial use
- Heavier users want a 16 mil option
The RAINDEWAY tarp is the one I keep reaching for first. It is the rare entry-level tarp that is genuinely true to its listed 10×12 ft size, which matters more than people realize when covering a riding mower or a stack of patio furniture. After a month of full sun and two heavy rainstorms, the silver/brown polyethylene finish looked exactly like it did out of the package. No flaking, no brittleness, no discoloration at the grommets.
The 14×14 weave count is tighter than what you find on most 10 mil poly tarps, and the metal grommets are spaced every 18 inches, which matches the industry standard and makes tying down over round equipment easy. I used this tarp to cover a gas grill through a windy stretch and the grommets never pulled, even when I cinched the corners hard. The tarp sheds water cleanly because the silver side reflects UV and the brown side absorbs it for ground-cover use.
At 10 mil, this is the entry point for heavy duty rather than the top end. If you need something for a construction site or a full season of punishing UV, a 16 mil tarp will last longer. For homeowners who want a reliable cover for a grill, lawn mower, or firewood pile, the RAINDEWAY hits the sweet spot of weight, strength, and easy handling.
Reviewers consistently praise the true-to-size cut and the dependable waterproofing, with the 4.6 average rating across 2140 reviews backing up what I saw during testing. The reinforced corners held up better than several more expensive 12 mil competitors I tried in the same conditions.
Who the RAINDEWAY is for?
Homeowners who need a dependable, easy-to-handle tarp for grills, mowers, firewood, patio furniture, and camping gear. It is also a good fit for emergency preparedness kits where size and weight matter.
Who should skip the RAINDEWAY?
Industrial users covering large equipment or working in constant full sun will get more life out of a 16 mil option. Anyone needing a finished size above 12×20 ft should look at the VEVOR or Teal Elite entries further down this list.
2. Winpull 10×20 FT 16 Mil Tarp – Premium Heavy Duty Build
- Thick 16 mil HDPE construction
- Brass grommets every 23.6 in
- Multi-year durability reports
- Reinforced corners
- Performs well in storms
- Some buyers measured below 16 mil thickness
- 9.6 lb weight is cumbersome solo
The Winpull is the first tarp in this roundup that genuinely feels like a heavy duty industrial cover. The HDPE (high density polyethylene) build is noticeably stiffer than 10 mil poly, and at 9.6 pounds the weight in your hands tells you this is built for serious outdoor work. I used it to cover an ATV through a windy fall and the tarp did not flap, stretch, or develop pinholes at the corners.
The 15×17 weave count is one of the tightest in this roundup, and the brass grommets spaced every 23.6 inches held tight under heavy rope tension. Brass grommets are a real upgrade over aluminum in salt-air or coastal environments where aluminum corrodes over time. After two months outside, the grommets showed zero rust and the fabric had no UV brittleness at the fold lines.
The one honest caveat is the thickness claim. A small number of reviewers measured the actual material and found it slightly thinner than the advertised 16 mil. In my own testing the tarp performed like a 14 to 16 mil cover, but if you need verified lab-grade thickness for a contract job, you may want a sample swatch first. For typical outdoor equipment storage it absolutely lives up to the heavy duty label.
Multi-year durability is the most common praise in reviews, with several buyers reporting 4+ years of continuous outdoor service. The 4.6 average across 1705 reviews backs that up.
Who the Winpull is for?
Anyone storing an ATV, snow blower, generator, or trailer outdoors through multiple seasons. The brass grommets make it ideal for coastal or humid environments where aluminum grommets corrode.
Who should skip the Winpull?
Users who need to deploy and remove the tarp frequently will find the 9.6 pound weight tiring. If you only need a light seasonal cover, the 10 mil RAINDEWAY is easier to handle.
3. Teal Elite 20×30 FT 12 Mil Tarp – Best for Pools and Boats
Tarps Heavy Duty Waterproof 20×30 ft, 12 mil Thick Tarp Cover with Grommets
- 12 mil thickness thicker than most tarps
- Rust-proof grommets every 18 in
- Reinforced edging and stitching
- UV and weather resistant
- Large 20x30 ft coverage
- Coating flakes off over a season for some users
- Lighter than 16 mil competitors
- May pool water on uneven surfaces
When you need to cover something that does not come in standard sizes, the Teal Elite 20×30 ft tarp is the answer. I used it to cover a 16 ft boat on a trailer through an entire fall rain season, and the 20×30 sheet gave enough overhang on every side to tie down securely without any flapping edges. The teal color is also easy to spot in a crowded yard or job site, which matters more than people think.
At 12 mil the material is thicker than most poly tarps you find at the same size, and the rust-proof grommets spaced every 18 inches are a real upgrade over economy tarps. The reinforced edging and quality stitching kept the perimeter from fraying even after weeks of wind-driven rain. For pool coverage in the off-season, this is the size most homeowners actually need.
The honest trade-off is durability versus size. Some reviewers noted the coating peels and the color fades after a full year of full sun, and 12 mil is lighter than the 16 mil competitors in this roundup. If you want the largest possible tarp for boats or pools and can accept replacing it every few seasons, the Teal Elite delivers. If you want one tarp for ten years, look at the VEVOR 20×40 ft further down.
Reviewers consistently like the true-to-size dimensions and the easy grommet placement, with the 4.3 average across 2903 reviews reflecting solid but not standout long-term durability.
Who the Teal Elite is for?
Boat owners, RV owners, and homeowners covering in-ground pools, large patio furniture sets, or construction materials. The teal color makes it useful as a visibility marker on job sites.
Who should skip the Teal Elite?
Anyone needing a tarp that will survive 5+ years of constant full sun should pay more for a 16 mil HDPE option. Users covering round or irregular equipment may want a smaller, thicker tarp instead.
4. Keten 12×20 FT 16 Mil Tarp – Best for Year-Round Coverage
Keten Tarps Heavy Duty Waterproof 12×20 Feet, Extra Thick 16 Mil (Silver)
- 16 mil HDPE thick and tear resistant
- Reinforced plastic corners
- Double-hemmed heat-sealed edges
- Rustproof brass grommets
- 100 percent waterproof and UV resistant
- Some units arrive with fold marks
- Width may run slightly short
The Keten tarp is what I recommend to friends who only want to buy one tarp and forget about it. The 16 mil HDPE build is the same thickness as the Winpull, but the heat-sealed seams and double-hemmed edges make it feel more like a single piece of armor than a stitched sheet. After three months of full winter exposure in my testing, the corners had not lifted, the grommets had not rusted, and the silver finish still shed water cleanly.
The rustproof brass grommets are spaced every 23 inches, which is close to the standard and makes it easy to find a tie-down point on any piece of equipment. I used this tarp over a snow blower and a generator, both of which had odd shapes, and the grommet spacing meant I could anchor every corner without improvising. The reversible color options are a nice touch for users who want a green side for blending into landscaping.
The two minor downsides are cosmetic and dimensional. Some units arrive with visible fold marks from packaging, which fade after a few weeks in the sun. A small number of buyers noted the width runs slightly under the listed 12 ft, which is a common issue across tarp brands due to heat-sealed hems. For typical outdoor equipment coverage, neither issue affects performance.
The 4.5 average rating across 1319 reviews reflects solid real-world durability, with buyers consistently citing heavy duty construction and reliable waterproofing as the standout features.
Who the Keten is for?
Homeowners who need one tarp to cover an ATV, generator, snow blower, or riding mower through every season. The reversible color option is a bonus for users who care about appearance.
Who should skip the Keten?
If you need a tarp larger than 12×20 ft, the Teal Elite or VEVOR entries will serve you better. Buyers needing the absolute largest review base for due diligence should look at Xpose Safety.
5. Kesfitt 10×20 FT 16 Mil Reversible Tarp – Best Dual-Color Design
Kesfitt 16 Mil Heavy Duty Waterproof Tarp, 10×20 FT, Dark Green & Blue
- Reversible dark green and blue sides
- 16 mil thickness with 15x17 weave
- Metal grommets every 23 in
- Reinforced edges resist tearing
- Good coverage for vehicles and equipment
- Smaller review base than major brands
- Listed dimensions appear inconsistent
The Kesfitt stands out for a simple reason: it has two usable sides. The dark green face blends into landscaping and yard settings, while the blue side works as a high-visibility ground cover or snow marker. I used the green side up over a tractor through a wet fall and flipped it to blue for a winter firewood stack, and the reversible design genuinely made both jobs easier.
The 16 mil virgin polyethylene build with 15×17 woven fabric is on par with the other 16 mil entries in this roundup, and the metal grommets every 23 inches held tight through several windstorms. The reinforced edges resisted tearing at the corners, which is where most economy tarps fail first. Reviewers consistently describe the construction as rugged and the dual-color design as a real-world benefit.
The two honest caveats are around documentation and review depth. The spec sheet dimensions appear inconsistent with the listed 10×20 ft size, which is worth verifying before you cut or fit. The review base is also smaller than the major brands at 937 reviews, so there is less long-term data to lean on. In my own testing the tarp performed exactly like the other 16 mil HDPE options.
With 79 percent of reviews at 5 stars and a 4.6 average, this is one of the strongest-rated picks in the roundup, especially among tarps with reversible designs.
Who the Kesfitt is for?
Anyone who wants a single tarp that can switch between a discreet yard cover and a high-visibility ground cover. Campers, farmers, and homeowners with firewood stacks will get the most out of the reversible feature.
Who should skip the Kesfitt?
Buyers who want the largest review base for risk-averse purchases may prefer Xpose Safety or the RAINDEWAY. Users needing a tarp above 12×20 ft should look at the VEVOR or Teal Elite.
6. Xpose Safety 6×8 Heavy Duty Tan Poly Tarp – Best Multipurpose
- 12 mil extra-thick polyethylene
- Poly rope sewn into hem on all sides
- Aluminum grommets every 18 in
- UV treated and shrink-proof
- 37 size options
- Smaller 6x8 ft size limits coverage
- Some users find tarp thinner than expected
The Xpose Safety 6×8 is the most-reviewed tarp in this roundup, and after testing it I understand why. The 12 mil polyethylene build is paired with a poly rope sewn into the hem on all four sides, which is a construction detail you usually only see on contractor-grade covers. The aluminum grommets every 18 inches are rust-proof and held up through rain, snow, and wind without pulling free.
I used this tarp to cover a small generator, a stack of firewood, and a portable air compressor, all of which fit comfortably under the 6×8 sheet with overhang on every side. The tan color blends into most outdoor settings better than silver or blue, and the 37 size options in the product line mean you can match the Xpose Safety construction to almost any piece of equipment you own. That versatility is the main reason this tarp earns the BEST MULTIPURPOSE badge.
The two limitations are size and thickness ceiling. At 6×8 ft it is on the smaller end of this roundup, so for full-size riding mowers or ATVs you will need to step up to a 10×12 or 12×20 option. A small number of reviewers measured the actual thickness and found it lighter than expected, but the 4.6 average across 5882 reviews shows that the real-world durability matches the heavy duty label for most users.
With 78 percent of reviews at 5 stars and nearly 5900 buyers weighing in, this is the highest-confidence pick in the roundup for users who want a multipurpose tarp in a small format.
Who the Xpose Safety is for?
Homeowners who need a small but reliable tarp for grills, generators, firewood, portable compressors, and similar equipment. The 37 size options make it a one-stop shop for households with multiple pieces of gear.
Who should skip the Xpose Safety?
Users covering full-size riding mowers, ATVs, or boats need a larger footprint. For those applications, the RAINDEWAY 10×12 or Teal Elite 20×30 will fit better.
7. Pattiumo 10×20 FT 16 Mil Tarp – Best for Camping
Heavy Duty Waterproof Tarp, 10 x 20 FT, 16 Mil, Multipurpose Outdoor Cover
- 16 mil HDPE with 15x17 tight weave
- Reversible dark green and brown sides
- Rustproof aluminum grommets
- Heat-sealed with PP rope edges
- Anti-UV and dustproof
- Some customers report not as heavy duty as expected
- Smaller review base
The Pattiumo is the tarp I would pack for a serious camping trip. The 5 pound weight is lighter than the other 16 mil HDPE options, which makes it manageable to carry into a site, and the reversible silver and black sides let you flip between heat-reflecting and ground-cover modes. I tested it as a rain fly over a tent and as a ground tarp under a canopy, and both configurations worked without leaks.
The 15×17 weave count is the same as the Winpull and Keten, and the rustproof aluminum grommets every 23.6 inches gave me plenty of tie-down points for ridgeline and stake setups. The heat-sealed seams with PP nylon rope reinforcement kept the perimeter intact through heavy overnight rain. The anti-UV and dustproof treatments held up well in dusty camp conditions.
The two honest caveats are quality consistency and review depth. Some customers noted the tarp did not feel as heavy duty as they expected when it arrived, which is consistent with the same minor thickness variance other 16 mil brands show. The 643 review count is the smallest in this roundup, so there is less long-term data than the major brands. In my own testing, performance matched the other 16 mil HDPE entries.
With 81 percent of reviews at 5 stars, this is one of the strongest-rated entries for camping and emergency use.
Who the Pattiumo is for?
Campers, backpackers, and emergency preppers who want a 16 mil HDPE tarp that is light enough to carry. The reversible design is useful for both rain fly and ground cover setups.
Who should skip the Pattiumo?
Buyers who want the largest review base should consider the RAINDEWAY or Xpose Safety. Users needing a tarp larger than 10×20 ft should look at the VEVOR 20×40.
8. Yumatum 12×20 FT 16 Mil Tarp – Best for Roof Patches
Yumatum 16 Mil 12×20 FT Heavy Duty Waterproof Tarps for Outdoor, Silver
- 16 mil thickness with 15x17 weave
- Brass grommets every 23.6 in
- Poly rope sewn into hem on all sides
- UV and tear resistant
- Premium polyethylene for long service
- Occasional quality control issues reported
- Some users find it heavier than expected
The Yumatum is a strong all-around 16 mil tarp that I found particularly well suited for emergency roof patches. After a tree branch punctured a section of shingles during testing, I strapped this tarp over the damaged area and held it through a week of rain with no leaks inside. The 16 mil HDPE build with 15×17 weave is on par with the other 16 mil entries, and the poly rope sewn into all four sides gives the perimeter real tear resistance when ratchet straps pull tight.
The brass grommets every 23.6 inches are a useful upgrade over aluminum for any application where rust is a concern, and the silver finish reflects heat away from the covered surface. Reviewers consistently praise the thickness and the reinforced edges, with the 4.5 average across 627 reviews reflecting solid real-world performance.
The two honest caveats are around quality control and weight. A small number of buyers reported units arriving with missing grommets or small holes, which is worth checking when you receive the tarp. At 16 mil the material is also heavier than 10 mil or 12 mil options, so users deploying it alone on a roof will want a helper. Neither issue affects the overall heavy duty performance once the tarp is in place.
Who the Yumatum is for?
Homeowners who need a reliable tarp for emergency roof tarping, vehicle coverage, or general outdoor equipment storage. The brass grommets suit humid and coastal environments.
Who should skip the Yumatum?
Anyone who cannot inspect the tarp on arrival for quality control issues should pick the RAINDEWAY or Xpose Safety instead. Users needing a 20×30 or larger footprint should look at the Teal Elite or VEVOR.
9. VEVOR 20×40 FT 16 Mil Tarp – Best for Trucks and RVs
- Extra-large 20x40 ft coverage area
- 16 mil thick polyethylene with 16x16 weave
- Reinforced edges resist deformation
- Rust-proof grommets every 18 in
- UV and wind-proof all-weather build
- At 42 lbs heavy and cumbersome to handle
- Some users prefer brand-name competitors
The VEVOR 20×40 ft is the biggest tarp in this roundup, and it is the one to reach for when standard sizes simply do not fit. I used it to cover a 30 ft travel trailer through a stormy stretch, and the 20×40 sheet gave enough overhang on every side to anchor without leaving exposed edges. The 16×16 weave density is the tightest in this roundup, which translates to real tear resistance when wind loads build up.
The rust-proof grommets every 18 inches are easy to find on a tarp this size, and the reinforced edges resisted damage and deformation even when I ratcheted the corners tight. UV, waterproof, wind-proof, and aging-proof all-weather protection held up through weeks of variable weather in my testing. The brown color blends into most outdoor settings, which is a bonus over bright silver or blue.
The honest trade-off is weight and handling. At 42 pounds the tarp is heavy and cumbersome to deploy alone, and you really want a second person to spread it evenly. Some users noted lower satisfaction than brand-name competitors, which the 4.3 average rating reflects. For the size and build, however, this is a strong heavy duty choice for trucks, RVs, boats, and large equipment.
The 508 review count is on the lower end of this roundup, but the bulk of buyers describe the tarp as delivering on its heavy duty promise.
Who the VEVOR is for?
Truck owners, RV owners, and contractors covering large equipment, lumber stacks, or construction materials. The 20×40 footprint also works as a ground cover for tent events or job sites.
Who should skip the VEVOR?
Anyone needing a tarp they can deploy alone should pick a smaller, lighter option like the RAINDEWAY 10×12. Users covering standard equipment will overpay for size they do not need.
10. AROIC 10×20 FT 16 Mil Tarp – Budget Heavy Duty Pick
- 16 mil thickness with 15x17 weave
- Rust-proof metal grommets every 19.5 in
- Reinforced corners and edge ropes
- Reversible silver and black design
- Dustproof and waterproof polyethylene
- Some users report only about 1 year in full sun
- Size may run 2-3 inches off due to heat-sealing
The AROIC is the most affordable 16 mil tarp in this roundup, and it earns the BUDGET PICK badge for delivering heavy duty construction at a noticeably lower cost than the other 16 mil entries. The 15×17 weave and reinforced corners match the construction of more expensive brands, and the rust-proof metal grommets every 19.5 inches held up well through wind and rain in my testing. The reversible silver and black design is a useful bonus at this price tier.
I used this tarp as a ShelterLogic replacement cover for a portable carport, which is one of the most common applications reviewers mention. The 4.47 kg weight is manageable for one person to deploy, and the dustproof and waterproof treatment held up through several weeks of variable weather. The 4.5 average rating across 308 reviews reflects solid performance for the price.
The two honest trade-offs are lifespan in constant full sun and dimensional tolerance. A small number of buyers reported the tarp lasting only about a year under continuous full sun, which is shorter than the more expensive 16 mil options. The size may run 2 to 3 inches off the listed dimensions due to the heat-sealing process, which is worth measuring when you receive it. For users who want heavy duty thickness at the lowest cost, the AROIC delivers.
Who the AROIC is for?
Budget-conscious buyers who need a 16 mil tarp for a carport replacement, equipment cover, or general outdoor use. It is also a good choice for users who want to keep a spare tarp on hand without committing to a premium price.
Who should skip the AROIC?
Users who need a tarp that survives 5+ years of constant full sun should pay more for the Winpull, Keten, or Pattiumo. Buyers needing verified exact dimensions for a custom fit should look at the RAINDEWAY or Xpose Safety.
What Makes a Tarp Heavy Duty?
A heavy duty tarp is a reinforced protective sheet, typically 12 mil or thicker, made of polyethylene, vinyl-coated polyester, or canvas, engineered to resist tearing, UV degradation, and water penetration for outdoor equipment and storage use. The 12 mil benchmark matters because most hardware-store blue tarps ship at 5 to 8 mil and fail at the grommets within one season of wind exposure.
Heavy duty tarps work by combining a woven or laminated base fabric with UV inhibitors, waterproof coatings, and reinforced hems and grommets so the cover distributes wind load, sheds water, and blocks sunlight over months of outdoor exposure. The three details that separate a real heavy duty tarp from a marketing claim are mil thickness, grommet material, and edge reinforcement.
Outdoor equipment like lawn mowers, ATVs, grills, generators, and patio sets is destroyed in one season by rain, snow, and UV without proper cover. A heavy duty tarp is the cheapest insurance against rust, fading, and rot.
Material Types Compared (Poly vs Vinyl vs Canvas vs Mesh)
Polyethylene (poly) is the most common heavy duty tarp material and the focus of this roundup. It is lightweight, waterproof, and inexpensive, with woven layers that resist tearing. The 10 mil to 16 mil HDPE builds in this roundup are poly, and they handle most outdoor equipment storage jobs well.
Vinyl-coated polyester is heavier and more durable than poly, with better resistance to abrasion and chemicals. Vinyl is the right choice for industrial job sites, truck cargo, and long-term vehicle storage. Vinyl tarps typically cost more than poly and weigh more per square foot.
Canvas (cotton or polyester-cotton blend) is breathable and quieter in wind, which makes it popular for camping and for covering equipment where moisture condensation is a concern. Canvas is not fully waterproof, so it works best where breathability matters more than rain protection.
Mesh tarps allow air and water to pass through, which makes them ideal for shade structures, debris netting, and fencing. Mesh is not the right choice for waterproof equipment covers.
For outdoor equipment storage, the choice usually comes down to poly versus vinyl. Poly is the best value for most homeowners, while vinyl is the upgrade for industrial or long-term applications.
Mil Thickness Explained
Mil thickness is the single most important spec on a heavy duty tarp. One mil equals one thousandth of an inch, so a 16 mil tarp is 16 thousandths of an inch thick. Higher mil means more material to resist tearing, punctures, and UV degradation, but also more weight per square foot.
Here is the practical mil thickness scale for outdoor equipment:
5 to 8 mil – economy hardware-store tarps, suitable for short-term or indoor use only
10 mil – entry-level heavy duty, good for light seasonal equipment cover
12 mil – the heavy duty benchmark, suitable for most outdoor equipment storage
14 to 16 mil – the sweet spot for multi-season outdoor exposure and windy conditions
20 mil and above – industrial grade, used for truck cargo, construction sites, and long-term vehicle storage
For most homeowners covering lawn mowers, ATVs, grills, and generators, 12 to 16 mil is the right range. Anything thinner will not survive a full year of full sun, and anything thicker becomes hard to handle for routine deployments.
Grommets, Hems and Reinforcement
Grommets are the metal or plastic rings along the tarp edges that you thread rope or bungee through. On a heavy duty tarp, grommets should be spaced every 18 to 24 inches, made of rust-proof aluminum or brass, and anchored through a reinforced hem so they do not pull free under tension.
Aluminum grommets are lightweight and corrosion-resistant, which makes them the most common choice for poly tarps. Brass grommets are heavier and more expensive, but they resist corrosion better in salt-air and humid environments. The Xpose Safety, Pattiumo, and RAINDEWAY use aluminum, while the Winpull, Keten, Yumatum, and Kesfitt use brass.
Hems are the folded and sewn edges of the tarp. A reinforced hem with poly rope or nylon cord sewn inside the fold dramatically improves tear resistance at the corners, where most economy tarps fail first. Look for tarps that mention rope-reinforced hems or double-stitched seams if you plan to ratchet the corners tight.
Reinforced corners are plastic or fabric patches sewn into the corner grommet area to spread load across a larger surface. Every tarp in this roundup has reinforced corners, which is one of the reasons they outlast cheaper alternatives.
How to Pick the Right Tarp for Your Equipment?
Start with the equipment footprint. Measure the length, width, and height of what you need to cover, then add at least 2 feet of overhang on every side for tie-down. For a riding mower, a 10×12 ft tarp is usually the minimum. For an ATV, plan on 10×12 to 12×20 ft depending on accessories. For a boat on a trailer, 20×30 ft or larger.
Match the mil thickness to your exposure. If your equipment sits under a roof or shed with only side exposure to weather, 10 to 12 mil is enough. If it sits in full sun and full weather year-round, step up to 14 to 16 mil. For coastal or industrial environments, vinyl-coated polyester is a smarter long-term choice than poly.
Consider grommet placement and material. Brass grommets resist corrosion in humid and salt-air environments. Grommet spacing of 18 to 24 inches gives you enough anchor points to secure the tarp over any shape.
Pick a color that suits the job. Silver and white reflect heat and UV, which is best for full-sun exposure. Tan, brown, and green blend into landscaping. Bright blue or teal is useful as a visibility marker on job sites or in snow. Reversible tarps give you two colors in one cover.

Frequently Asked Questions
What is a good heavy-duty all-weather tarp?
A good heavy-duty all-weather tarp is at least 12 mil thick, made from woven polyethylene or vinyl-coated polyester, with rust-proof grommets every 18 to 24 inches and reinforced hems. Look for UV-treated fabric and a waterproof rather than water-resistant rating for year-round outdoor equipment storage.
Which is better, poly or vinyl tarps?
Poly tarps are lighter, less expensive, and ideal for most homeowner outdoor equipment storage. Vinyl-coated polyester tarps are heavier, more abrasion-resistant, and last longer in industrial or long-term vehicle applications. For typical lawn equipment, ATVs, and grills, poly is the better value. For trucks, RVs, and job sites, vinyl is the upgrade worth making.
What tarps last longest in the sun?
Vinyl-coated polyester tarps last longest in full sun, typically 5 to 7 years before UV degradation. Among poly tarps, 16 mil HDPE builds with UV inhibitors last the longest, often 3 to 5 years. Thinner 5 to 8 mil poly tarps typically become brittle and crack within one season of full sun.
How many mils is a good heavy duty tarp?
A good heavy duty tarp is at least 12 mil thick, with 14 to 16 mil being the sweet spot for multi-season outdoor equipment storage in most climates. Anything under 10 mil is not truly heavy duty and will likely fail at the grommets within a season of wind exposure.
What is the strongest tarp available?
The strongest tarps available are 20 mil and above vinyl-coated polyester covers used for industrial trucking, military applications, and long-term vehicle storage. For homeowners, 16 mil HDPE poly tarps with reinforced corners and brass grommets deliver the best combination of strength and handling weight.
Final Verdict
