Gravel-Lok® Amber vs Clear

Gravel-Lok® CLEAR Bond

  • Colorless to light yellow color (for white or any color stone)
  • Contains UV additives
  • Initially enhances stone color and has a shiny, wet look. Will stay shiny for 1 – 2 months or indefinitely, depending on amount of use.
Gravel-Lok® CLEAR Bond

Gravel-Lok® AMBER Bond

  • Amber colored (will discolor light / white stones)
  • Matte finish
  • Does not contain UV additives
  • Considerably less expensive than Gravel-Lok® Clear
  • Initially darkens stone and has a shiny, wet look. Dark color may change to have an amber/brown/greenish look and intensify in first few months. Then, Gravel-Lok fades off surface of stone (70 – 80%) exposing natural color and matte finish of stone. This process, depending on exposure to sun, will take anywhere from 2 – 6 months from initial application. Lighter colored stones will adopt an amber hue.
