70% Black Shade Cloth 20 x 20 ft Durable Mesh Tarp - Garden & Patio

Our review of the 70% Black Shade Cloth (20 x 20 ft) finds it useful for gardeners and property owners who need broad, affordable sun protection. The single biggest reason to buy is straightforward: it creates a significantly cooler, shaded area while still allowing airflow and water to pass through, which helps plants, patio spaces, or animal enclosures stay comfortable without trapping heat. The cloth is built from high density polyethylene with reinforced edges and grommets, and although material thickness and long-term durability receive mixed feedback, it performs well for seasonal or light-duty outdoor shading.

Key Features

• 70% Shade Rate: Blocks the majority of direct sunlight to create a cooler, shaded environment while still allowing about 30% of light through for plants.
• High density polyethylene: Lightweight and breathable material that provides good airflow and resists stretching under normal use.
• Lock-stitch knitting: Prevents unraveling at the weave so the fabric keeps its structure during handling and mounting.
• Taped edge and reinforced corners: Extra strength at stress points helps reduce tearing when the cloth is secured or tensioned.
• Grommets every 40 in: Preinstalled attachment points along the reinforced edges make setup straightforward and let you tension the tarp evenly.
• Easy to clean: Breathable fabric lets water and dirt pass through and can be rinsed clean with a garden hose.

Who It's For

The shade cloth suits backyard gardeners, small greenhouse owners, and people who need temporary or seasonal shade for patios, chicken coops, kennels, or barns. It is strongest as a ventilated sun block where airflow matters and where full light exclusion is not required.

Those seeking a heavy-duty, permanent roofing material or a very thick, long-life industrial tarp should look elsewhere, since some customers report concerns about material thickness and durability over many months of continuous use.

Pros & Cons

Pros

• Provides effective 70% shade while keeping air moving for cooler conditions.
• Lightweight HDPE fabric is easy to handle and mounts quickly using grommets every 40 in.
• Reinforced taped edge and corners plus lock-stitch knitting add strength and reduce fraying.
• Simple to clean with a hose and lets rain pass through without pooling.

Cons

• Some buyers report the material feels thin and may tear after several months, so it may not suit heavy, long-term exposure.
• Because the fabric is stretchable, measured side lengths can vary slightly from the stated dimensions.

Our Verdict

For gardeners and homeowners who want an affordable, breathable shade solution, this 70% shade cloth is a practical choice that balances light reduction and airflow. It offers good design details like reinforced edges and regularly spaced grommets, but those needing a heavy-duty, multi-year installation should weigh the mixed feedback about material thickness and durability.
