Horizon™ The Indoor Outdoor Surface Adhesive

Horizon™

The Indoor & Outdoor Surface Adhesive

Integra Horizon is a high-performance 10:1 two-part methacrylate adhesive engineered for demanding interior and exterior surface fabrication. Designed to deliver exceptional bond strength, UV resistance, and long-term color stability, Horizon performs where other adhesives fall short — whether in luxury kitchens, outdoor entertaining spaces, or exposed architectural installations.

Available in a comprehensive color-matched range for leading surface brands, Horizon is ideal for seaming, mitering, laminating, and vertical applications. For fabricators who need reliable performance across changing environments, it is the trusted choice for projects that demand weather-resistant, long-lasting results.

Built to perform in the harshest conditions

Horizon has proven performance on quartz, porcelain, ceramic, sintered stone, and natural stone for both interior and exterior applications. It features exceptional UV and weather resistance, making it ideal for outdoor kitchens, pool edges, exterior cladding, and flooring exposed to harsh environmental conditions.

With a fast 9–14 minute working time and a 20–30 minute fixture time, Horizon supports efficient fabrication without sacrificing control. Its no-sag consistency is perfectly suited for vertical seams and miters, while excellent color stability ensures seams remain visually consistent over time — even under direct sunlight.

Once cured, Horizon withstands temperature cycling from -40°F to 158°F, meeting the real-world demands of modern surface fabrication.

Performance without compromise

Horizon is GREENGUARD Gold certified and formulated with low VOCs, supporting healthier indoor air quality while maintaining the strength, durability, and weather resistance professionals expect from Integra Adhesives.
