What You Need To Know About Gravel-Lok

Gravel-Lok has been scientifically created to bond with a number of aggregates. It's a single component, moisture-curing liquid.  When combined with Cell-Tek's LSG Series Load Support Grid,  it's an absorbent, long-lasting natural stone surface that can be used in a large variety of civil, residential, and industrial applications. This product is an excellent choice for parks, cities, and other projects with pervious surfaces (such as concrete)  as well as for stone scaping in residential areas.

Gravel-Lok comes in either clear or amber and each is available in one-gallon size, 5-gallon buckets, or 50-gallon drums.

Clear Gravel-Lok Bond

This clear bond is colorless or a very light yellow.  It's perfect for white or any other color of the stone.

Amber Gravel-Lok Bond

• The amber color can discolor light or white stones.
• Offers a matte finish
• Does not contain UV additives
• A lot less expensive than the Clear Gravel-Lok Bond

At first, it will darken the stone and create a shiny wet look. Dark colors may change and appear as brown, amber, or greenish which will intensify over the first few months. The Gravel-Lok will fade from the surface of the stone by 70 to 80% leaving behind the natural color and matte finish of the actual stone. This color-changing depends on exposure to the sun. It can take up to 2 – 6 months after the first application. Lighter-colored stones will take on an amber shade.
