Pros and cons

Pros

The claimed 90% sun blocking offers substantial shade while the listing says some light still passes through for plants.
Air and rain can pass through the mesh, so it can shade an area without forming a solid rain cover.
Grommets and reinforced binding offer multiple attachment points for rope or zip ties.

Cons

The open-knit fabric will not keep rain out, so it is unsuitable when waterproof coverage is needed.

Frequently asked questions

Does this shade cloth keep rain out?

No. The listing describes open-knit HDPE mesh that allows rain and water to pass through, so it is not a waterproof cover.

How much sun does it block?

The listing claims 90% sun blocking and says it blocks up to 90% of harmful UV rays. These are seller claims, not independently verified measurements.

How is it attached?

It has metal grommets along reinforced binding tape. The listing advises securing every grommet, using rope or zip ties as possible fasteners. Separate fasteners are not specified as included.

Is this model custom-sized?

The listing promotes custom sizes but also identifies this item as 12'X 12'. Confirm the selected size with the seller if custom dimensions are important.
