ShadeMart 6 ft x 19 ft Blue Waterproof Shade Sail - Cool, Durable

In this review the ShadeMart 6 ft x 19 ft Blue Waterproof Shade Sail is judged on durability, sun protection and ease of use; it is a practical canopy for homeowners who need a simple way to add shade and light rain protection to a patio, carport or backyard. The biggest reason to buy is its combination of a waterproof PU coating and a high level of sun protection, which together reduce surface temperatures and make outdoor spaces more usable during hot weather. The sail ships in a custom size option and is clearly aimed at DIY installs rather than permanent structures.

Key Features

• Waterproof fabric: Polyester with a PU waterproof coating blocks light rain and resists wind-driven moisture so outdoor seating areas stay drier.
• High UV blockage: The fabric blocks up to 95% of harmful UV rays, helping reduce surface temperatures by as much as 15 degrees compared with no shade.
• Reinforced edges: Dual-layer white webbing under the fabric and curved edges add strength where the sail is most stressed during tensioned installation.
• Stainless hardware-ready corners: Corners finished with stainless steel D rings attached to the webbing make it easy to secure the sail to anchors and hardware.
• Custom size option: ShadeMart offers custom sizes that usually take about two business days to prepare, which helps match unusual patio or carport dimensions.
• Simple maintenance: The sail is compact and straightforward to install or remove for seasonal use or winter storage.

Who It's For

The ShadeMart sail is for homeowners and renters who want a cost-effective, temporary canopy that provides strong UV protection and some waterproofing for patios, decks, small carports and backyard seating areas. It is especially useful for people who prefer a DIY approach and who can tension the fabric to avoid sagging and water pooling.

It is not ideal for those seeking a permanent, load-bearing awning or for locations that regularly see heavy storms and standing water, since the sail can withstand light rain but may be at risk from water accumulation or tearing in severe weather.

Pros & Cons

Pros

• Good build quality with strong stitching and reinforced corner loops for reliable mounting.
• Effective shade with up to 95% UV blockage and measurable temperature reduction on covered surfaces.
• Relatively easy to install and remove for seasonal use when paired with proper tensioning and hardware.

Cons

• Installation hardware is not included, so buyers need to purchase a separate kit to ensure proper tension and fit.
• Can handle light rain but is not suited to heavy storms or conditions where water can pool on the fabric.
