Product Overview:

The Everbuild Lumberjack 650 Hybrid Polymer Wood Floor Adhesive – 14kg is a professional-grade flooring adhesive designed for solid wood, engineered wood, and parquet installations. Developed using advanced hybrid polymer technology, this high-performance adhesive provides exceptional bond strength, flexibility, and water resistance for long-lasting results in both residential and commercial environments.

Completely solvent-free and low VOC, Lumberjack 650 is a safer, eco-friendly option for indoor use. It offers an extended open time of around 60 minutes, making it ideal for large-area flooring projects or where precise adjustments are required.
