Is gator board waterproof?

No, gator board is not waterproof. Its wood-fiber facing absorbs moisture over time, which can lead to warping and surface damage, so it is built for indoor use.

• The outer wood-fiber layers soak up humidity and standing moisture.
• Prolonged exposure can cause warping and degrade the printed surface.
• Keep gator board displays indoors and away from damp environments.
• For outdoor signage, choose a waterproof substrate such as PVC board or aluminum composite instead.
