ColourTree Custom Size 13ft x 20ft Blue Waterproof Shade Sail - UPF50

Our review of the ColourTree 13' x 20' blue shade sail finds it best suited for homeowners and small commercial spaces seeking a durable, waterproof canopy that blocks sun and rain. The single biggest reason to buy is the combination of heavy 220 GSM virgin polyethylene fabric with a waterproof coating and commercial UV treatment, which produces reliable shade, water resistance, and longer life than thin fabric alternatives. Installation is straightforward thanks to stainless steel D-rings and reinforced stitching, so it works well for patios, carports, and play areas where both rain protection and sun block matter.

Key Features

• 220 GSM virgin fabric: The thick non-recycled polyethylene provides a sturdy, dense cloth that resists stretching and holds shape under tension.
• Waterproof coating: A waterproof layer prevents water from passing through, so the canopy keeps areas dry during light to moderate rain.
• Commercial UV treatment: The UV resistant finish enhances long-term color retention and helps the sail deliver consistent UPF50 sun protection.
• 316 stainless steel D-rings: Premium grade metal D-rings at each corner simplify attachment points and resist corrosion in outdoor conditions.
• Double reinforced stitching: All edges use double stitched seams to reduce tear risk and distribute pulling tension to protect the D-rings.

Who It's For

This shade sail is ideal for homeowners who want a heavy-duty canopy for a patio, carport, yard, or play area and who value water resistance as well as strong UV protection. It also suits small commercial settings such as cafe outdoor seating that need both shade and occasional rain coverage.

Customers who need an exact premade size larger than 13' x 20' or who prefer fully permanent rigid roofing should look elsewhere; the sail is designed as a flexible, tensioned fabric solution rather than a fixed structure. Those requiring full heavy stormproof roofing may need a different product.

Pros & Cons

Pros

• High quality 220 GSM fabric feels substantial and resists sagging over time.
• Waterproof coating effectively blocks rain so outdoor surfaces stay dry underneath.
• 316 stainless steel D-rings and reinforced stitching make installation secure and durable.
• Commercial UV treatment helps maintain color and provides reliable shade performance.

Cons

• As a tensioned fabric canopy, it is not a permanent rigid roof and may need removal or extra securing in extreme weather.
• Custom sizing means lead times or measurement care are required to fit unique spaces.
