Tenax Gravity Knife Grade - 1 Gallon

Tenax Gravity Knife Grade – 1 Gallon is a high-performance, extra-clear vinyl ester stone adhesive engineered for professional fabricators who demand exceptional bonding strength, fast curing, and superior color stability. Designed for bonding and laminating granite, marble, quartz, ceramic, and other hard surfaces, this versatile adhesive delivers strong, durable results for demanding stone fabrication and installation projects.

Featuring a thick, knife-grade consistency, Tenax Gravity is ideal for vertical and horizontal applications, including countertop seams, edge laminations, and visible stone joints. Its extra-clear formula cures to a smooth, glossy finish that can be sanded and polished to blend with surrounding stone surfaces. The adhesive can also be tinted with compatible universal coloring pastes for improved color matching.

Engineered for reliable indoor and outdoor performance, Tenax Gravity offers excellent UV stability along with resistance to freezing and high temperatures. Its fast-setting formula provides a tack-free time of approximately 20–35 minutes at 77°F (25°C), helping fabricators complete projects efficiently without sacrificing bond strength or finish quality.

For optimal bonding performance, apply Tenax Gravity to clean, completely dry surfaces. Mix thoroughly with 1–3% catalyst by weight according to the manufacturer's technical data sheet. When custom color matching is required, add compatible coloring paste before introducing the catalyst. After use, keep containers tightly closed and store away from heat, humidity, and direct sunlight to maintain product quality.

Whether bonding natural stone, laminating countertop edges, or creating clean, professional-looking seams, Tenax Gravity Knife Grade provides the strength, clarity, and versatility required for professional stone fabrication.

Important: The approximate 20–35-minute tack-free time applies to a thin layer at 77°F (25°C) and does not indicate full cure. Always follow the manufacturer's current technical and safety data sheets for proper mixing, application, handling, and storage.
