Built Different

Every Super tarp starts with woven polyethylene and finishes with details that cheaper tarps skip.

Waterproof Construction

Laminated polyethylene fabric on both sides blocks rain, snow and ground moisture from reaching your gear.

UV Stabilized

UV treatments on both tapes and lamination layers keep your tarp strong through years of direct sunlight exposure.

Reinforced Grommets

Rustproof aluminum grommets every 18 inches with reinforced corners and heat-sealed hems prevent tearing at tie-down points.

Tear Resistant

16x16 weave count on heavy duty models creates a fabric that resists ripping even under wind load and heavy snow.

Acid Resistant

Chemical-resistant polyethylene stands up to acidic environments, fertilizer exposure and industrial settings.

Heat-Sealed Seams

Every seam and hem gets heat-sealed with poly twine inserted for reinforcement that outlasts stitched alternatives.

Three Steps to Protection

Getting the right tarp coverage takes minutes, not hours.

1

Measure Your Area

Measure the length and width you need covered, then add 6-12 inches per side for secure tie-down overlap.

2

Pick Your Weight

Choose 8 oz super heavy duty for permanent outdoor use, 6 oz heavy duty for seasonal coverage, or lighter options for temporary jobs.

3

Secure and Forget

Thread rope or bungee cords through the grommets every 18 inches. UV stabilizers and heat-sealed seams handle the rest.

About Super Tarps

Super started with one goal: build tarps that people buy once instead of replacing every season. Based in Montana, we understand what harsh weather does to cheap covers. Our tarps use woven high-density polyethylene laminated on both sides, with UV stabilizers baked into the tapes and lamination layers.

Every Super tarp features heat-sealed seams, rustproof aluminum grommets and poly twine reinforced hems. The result is a cover that handles snow loads, summer UV, acid exposure and continuous wind without breaking down at the stress points where lesser tarps fail first.

What Our Customers Say

Real reviews from verified tarp buyers across the country.

★★★★★

Worth Every Penny for Woodpile Coverage

I bought the 6x8 brown tarp to cover my woodpile and it held up through seven years of blistering sun and temperatures swinging from 90 degrees down to freezing. The eyelets, fabric and edges stayed strong and durable the entire time. For the smaller sizes, this tarp is absolutely worth the investment.

Six Years and Still Going Strong

This is my second purchase from this company. The first tarps I bought lasted about six years. I love how heavyweight they are. Ample reinforcement at the grommets and the heat-sealed seams have never leaked once. The brown color also blends well with my property rather than looking like a construction zone.

Perfect Outdoor Movie Screen

We ordered the white tarp thinking it would be a cheap test for an outdoor movie screen. Turns out it works perfectly and we never needed a more expensive option. The white surface reflects light evenly and the grommets make it easy to string up between trees. Doubled as a rain cover for our chicken coop afterward.

Neighborhood Book Swap Saver

We use tarps from this company to cover our neighborhood book swap during bad weather. They have never let water through, even during heavy rainstorms. The quality surprised me given what we paid. Thick material, good construction, and it cleaned right up in the spring after a full winter of snow and wind.

Replaced My Flimsy Blue Tarps Forever

I was tired of the flimsy blue tarps you can buy everywhere, including the pharmacy. I needed to cover bags of wood pellet fuel so they stay dry and these tarps delivered. Several different sizes purchased and all have lasted three years under snow, ice and sun. Tough, durable and worth buying once.

No More Ugly Blue Tarps on My RV

I bought the white tarp to cover an older 30-foot RV. I refused to use another blue tarp because they look terrible and fall apart after one season. This white one is thicker, looks cleaner against the RV, and lasted more than one full season of summer exposure without fading or tearing. The price-to-durability ratio beats anything else I tested.

Covered the Entire Haunted House

I bought several of these for a 10x30 haunted house setup. Instead of stitching together multiple 10x10 pieces, I covered the entire structure with single tarps. The black color blocked all light and the grommets made hanging walls easy. Sturdy enough to handle three weekends of crowds bumping into them.

RV Cover That Actually Holds Up

I put this tarp on my RV and the quality impressed me immediately. At 16 mil thick, it feels substantial in your hands. The grommets are sturdy and well-placed. Instead of spending big money on a custom carport canopy replacement, this tarp covered the whole thing at a fraction of the cost and held through the first winter storms.

Expert Recommendation

Marcus Dillon, Building Materials Consultant
I've tested dozens of tarp brands across construction and agricultural applications. Super tarps stand apart because of the 16x16 weave count on their heavy duty line, which creates a fabric density most competitors skip to save costs. The heat-sealed seams and reinforced corners at every grommet point mean these tarps fail at the center of the panel, not at the edges where you tied them down. For anyone covering equipment or materials outdoors for more than one season, the extra weight per square yard pays for itself.

Frequently Asked Questions

Common questions about Super tarps, materials and sizing.

The weight per square yard measures fabric density. An 8 oz tarp uses more polyethylene per area than a 4.5 or 6 oz tarp, creating a thicker, more durable cover. Super's 8 oz brown tarps are the heaviest in the lineup and suit permanent outdoor installations.

Mil measures thickness in thousandths of an inch. The 16 mil super heavy duty brown tarps are roughly 40% thicker than the 11-12 mil heavy duty models. Choose 16 mil for permanent outdoor use and 11-12 mil for seasonal coverage or lighter-duty applications.

Tarp sizes refer to the cut size before hemming. Heat-sealed hems with poly twine inserted consume about 6 inches per side, or roughly 2-5% of the total dimensions. A tarp listed as 10x12 feet will measure approximately 9'6" x 11'6" after finishing.

Heavy duty and super heavy duty tarps feature rustproof aluminum grommets every 18 inches along all sides, with reinforced corner grommets. Medium duty tarps like the green 4.5 oz model have grommets every 36 inches. Closer grommet spacing distributes wind load more evenly across the tarp.

Super tarps are waterproof. The woven polyethylene fabric gets laminated on both sides, creating a barrier that blocks liquid water completely. Heat-sealed seams prevent leaking at joints. The tarps also resist rot and dust penetration.

Brown tarps (8 oz, 16 mil) are the super heavy duty line built for permanent outdoor use. White tarps (6 oz, 11-12 mil) reflect heat and light, making them ideal for covering items that need to stay cool. Black tarps (6 oz, 11-12 mil) block light completely, useful for weed suppression and privacy.

Multiple customers report using Super tarps through full winters with heavy snow. The 16 mil brown tarps and 11-12 mil black/white tarps both resist tearing under snow weight. Proper grommet tie-downs every 18 inches prevent the tarp from sagging and concentrating snow load in one spot.

UV stabilizers are chemical compounds added to both the tape layers and lamination surfaces of the tarp. These compounds absorb ultraviolet radiation from sunlight before it can break down the polyethylene chains. Without UV stabilizers, a tarp exposed to direct sun would become brittle and crack within months.

The 12x25 foot super heavy duty brown tarp covers most RVs and large vehicles. For longer RVs (30 feet or more), the 10x30 foot white or black tarps provide full coverage. Measure your vehicle and add 2-3 feet per side for proper drape and tie-down room.

The red tarp provides bright visibility for construction zones, event markers, roadside setups and any application where the cover needs to be easily spotted. At 3.3 oz and 7-8 mil, it is lighter than the brown or black options but still waterproof and UV-protected.

Thread rope, bungee cords or zip ties through the grommets along all sides. Use stakes or weights at ground level. For roof or frame applications, run the rope through every grommet to distribute tension evenly. Leave enough slack for the tarp to shed water instead of pooling it.

All Super tarps use rustproof aluminum grommets. Aluminum resists corrosion from rain, salt air and acidic environments. The grommets are reinforced at the mounting points and at every corner to prevent tear-out under load.
