8ft x 21ft Blue Custom Size Waterproof Shade Cloth - 90% Sunblock

In this review of the 8' x 21' Blue Custom Size Waterproof Shade Cloth, the bottom line is simple: this is a practical, heavy-duty shade option for pet enclosures and outdoor shelters where high sunblock and airflow are priorities. The reviewer found it most compelling for dog kennels, chicken coops, and small greenhouse shading because it blocks about 90% of sunlight while still allowing wind to pass through, which helps keep animals cooler without trapping heat. The mix of durable mesh fabric and reinforced edges gives confidence for extended outdoor use.

Key Features

• 90% Shading Rate: Provides strong sun and UV protection while permitting air circulation to reduce ambient temperature in enclosures.
• Wide Applications: Works well on dog kennels, chicken coops, barns and pool areas for versatile outdoor sun control.
• Long-lasting Durability: Made from high-density polyethylene with UV and antioxidant treatment to resist sun and air damage over time.
• Easy Installation: Comes with grommets for securing the shade quickly and keeping it taut on fences or frames.
• Customization: Available in custom sizes and made domestically, which helps fit unusual openings and specific projects.

Who It's For

This shade cloth suits pet owners, small livestock keepers and homeowners who need a reliable, breathable screen for outdoor enclosures or privacy screening. It is especially helpful where heat relief and UV protection are needed but airflow must be maintained for animal comfort.

Those who need a decorative patio canopy or a completely waterproof tarp for heavy ponding may want to look elsewhere; this product is a mesh sunshade designed to reduce light and UV exposure rather than act as a fully sealed rain barrier in prolonged downpours.

Frequently Asked Questions

Is this shade cloth fully waterproof?
The mesh design blocks sun and light spray but is not a fully sealed tarp for prolonged heavy rain; it sheds light water but allows airflow.

Can I cut the cloth to a custom size?
The product is offered in custom sizes and can be trimmed, but trimmed edges should be reinforced when possible to maintain durability.

Are the grommets spaced well for installation?
Most buyers report grommets spaced every few feet and easy to use, though a few noted isolated issues with grommet installation damage.
