ColourTree Custom Size 4 ft x 18 ft Orange Waterproof Shade Sail

In this review the ColourTree Custom Size 4 ft x 18 ft orange shade sail is evaluated for homeowners and small business owners who need a robust, waterproof canopy that also blocks UV. The single biggest reason to consider this sail is its combination of thick 220 GSM virgin polyethylene fabric and a waterproof coating that keeps both sunlight and rain out, making it a practical replacement for a permanent awning on patios, carports and play areas. Installation is straightforward thanks to the stainless steel D-rings and reinforced stitching, so it suits DIY installers as well as contractors.

Key Features

• 220 GSM virgin fabric: Thick, non-recycled polyethylene provides a substantial barrier that resists tearing and holds its shape under tension.
• Waterproof coating: An added waterproof layer prevents water from passing through so the covered area stays dry in light to moderate rain.
• UPF50 and UV resistance: Commercial grade UV treatment helps block up to 95% of UV rays and reduces heat beneath the canopy.
• 316 stainless steel D-rings: Corrosion-resistant D-rings at each corner simplify mounting and last in outdoor conditions without rusting.
• Double reinforced stitching: All edges are finished to resist fraying and to support the D-rings under pull and wind stress.
• Three year limited warranty: Free replacement is offered if you are not satisfied during the warranty period, giving extra confidence in the purchase.

Who It's For

The ColourTree orange waterproof shade sail is ideal for homeowners, renters with outdoor patios, and small property owners who want a removable, heavy-duty canopy to shield seating areas, grills or parked vehicles. It works well where a bright color and reliable water resistance are desired, such as play areas, backyard astroturf, or a small carport.

It is less suited to people seeking a lightweight, packable sunshade for travel or very large commercial installations that require engineered mounting and wind load calculations. If you need a breathable shade for intense heat without trapping moisture, a non-waterproof shade cloth may be preferable.

Pros & Cons

Pros

• Thick 220 GSM material feels durable and resists tear and wear under tension.
• Waterproof coating reliably keeps water out in regular rainfall and helps keep areas dry.
• Good hardware and stitching, with 316 stainless steel D-rings and reinforced seams for long-term use.

Cons

• Waterproof sails can trap heat beneath them compared with breathable shade fabrics, so they may not cool as effectively on very hot days.
• Custom sizing means you should confirm measurements carefully before ordering, as returns will depend on the seller warranty terms.
