What Does Waterproof Mean for Acrylic?

When people ask whether acrylic is waterproof, they typically want to know whether water can damage the material.

Acrylic's non-porous surface prevents water from penetrating the material, which means it does not:

  • Swell
  • Rot
  • Rust
  • Absorb moisture

This makes acrylic a reliable material for environments where water exposure is common.
