What is Crazing?

What is Crazing? Also known as Veining or Marbling

Crazing refers to the appearance of thin, white marks or lines that sometimes form on marine-grade, solution-dyed acrylic canvas fabrics. These marks occur when the fabric’s protective finish fractures, typically due to folding or creasing during the sewing and fabrication process.

Causes of Crazing

Marine-grade acrylic canvas is coated with a specialised finish intended to improve water repellency, UV resistance, and provide stiffness essential for sewing and fabrication. When this protective coating is disturbed, often through folding or creasing, it can fracture, resulting in visible lines or marks known as crazing on the surface of the fabric.

Conclusion

We take great care when producing our umbrella canopies and protective covers, but we recognise that crazing can still occur, and we understand this can be frustrating. While these lines or marks might initially appear concerning, it’s important to remember that crazing generally doesn't affect the fabric's strength or overall performance. Typically, these cosmetic imperfections that will become less noticeable and resolve naturally over time.
