Where buyers hesitate
What are the primary durability concerns with this shade cloth?
Owners of sibling variants report grommets can tear easily and material may develop tears over time. Owners of sibling variants report that the grommets can tear very easily, especially when using ratchet straps to pull the fabric tight. One user noted that the material became frail and easily ripped after one year, with tears appearing near the securing rings. Another stated the material was subpar and tearing on the face of the shade, becoming a "perforated mess".
How effective is the TANG shade cloth at blocking rain?
The cloth protects against light rain but is not 100% waterproof. While described as waterproof and featuring waterproof strips on seams, community reports indicate that no shade sail is 100% waterproof. Water can slowly drip through stitching on seams, and if it pools, it will also drip through. To mitigate this, installation with a significant slope (20°-40° angle) is recommended to prevent water accumulation.
What are the true dimensions of the TANG 16' x 20' shade cloth when installed?
The listed size is for the stretched fabric, with actual width deviating 4-8 inches due to curves and stretch. The listing notes the fabric is stretchy and the title sizes are for when it's stretched tight, advising to fully extend it during installation. User reports indicate the actual dimensions can be 4-6 inches shorter in the middle width due to curved edges, and side length deviation can be 0-8 inches for these hand-made products.
How do I properly install the TANG waterproof shade cloth?
Install at a 20°-40° angle with maximum tension, ensuring the waterproof strip faces the ground. The shade sail should be installed at a 20°–40° angle with maximum tension to facilitate rainwater runoff. The side with the waterproof strip should face the ground. The listing also notes that the fabric is stretchy and the title sizes are for when it's stretched tight, suggesting fully extending the sail during installation or choosing a slightly bigger size.
Why we judge it this way
The TANG 16' x 20' Waterproof Shade Cloth is presented as a durable solution for outdoor shade and light rain protection, maintaining a 4.1-star average rating across 361 ratings. It is constructed from 260 GSM high-density Polyester shade fabric, which is coated to protect against light rain and designed to resist fading or tearing easily. This material also features waterproof strips applied to the fabric seams to enhance rain protection, making it weather-resistant for year-round use. The shade cloth is highly effective at sun block and cooling, blocking up to 95% of harmful UV rays and thereby reducing the temperature underneath the sail. This makes it ideal for various outdoor areas such as patios, lawns, gardens, backyards, pools, decks, courtyards, and carports, aiming to keep users cool in summer. The product also features thickened and straight edges with double-stitched reinforced seams, D-rings, and evenly distributed metal eyelets to enhance its tensile strength. The straight edge design is noted to increase the shading area, making it suitable for frame structures like pergolas and greenhouses.
However, user experiences, particularly from sibling variants and community feedback, highlight significant durability and waterproofing concerns. Multiple reports from owners of sibling variants indicate that the grommets can tear very easily, especially when significant tension is applied, such as with ratchet straps. This suggests that while the fabric itself is robust, the attachment points may be a weak link, potentially limiting its resilience in windy conditions or under substantial strain. It is advisable for potential buyers to consider reinforcing these points or using less aggressive tensioning methods during installation to prevent premature tearing.
Furthermore, the 'waterproof' claim faces scrutiny from community reports. While the listing states the fabric is coated to protect against light rain and has waterproof strips applied to seams, community discussions clarify that no shade sail from any manufacturer is 100% waterproof. Users report that water can slowly drip through the stitching on the seams, and if water is allowed to pool in the center, it will also slowly drip through. This implies the product is suitable for light showers but not heavy downpours, and proper installation with a significant slope (a 20°-40° angle) is crucial to facilitate rainwater runoff and prevent water accumulation, which could otherwise damage the fabric and anchor points. The listing itself advises installing the sail at a 20°–40° angle with maximum tension to facilitate rainwater runoff and specifies that the side with the waterproof strip should face the ground.
Concerns about material quality have also surfaced among owners of sibling variants. One review suggests that a recent purchase exhibited subpar material quality compared to previous versions, tearing easily on the face of the shade and becoming a "perforated mess". This inconsistency in quality, if widespread, could impact long-term satisfaction and the product's overall lifespan. Additionally, the listing notes that the fabric is stretchy and the title's sizes are for when it's stretched tight, advising users to fully extend the sunshade sail during installation or consider picking a slightly bigger size. User reports further indicate that actual dimensions can deviate, with the middle width being 4-6 inches shorter due to curved edges and side length deviations of 0-8 inches for hand-made products. Therefore, accounting for these potential size discrepancies is important for proper fit and tensioning.
