Stone PU Adhesive NBS: Block Adhesive Foam Instead of Mortar
Compared with cement-based mortar, a foam adhesive saves water, mixing tools, waste and weight on the scaffold. Stone PU Adhesive NBS is a ready-to-use, one-component block adhesive foam for fast and efficient bonding of stone-based building materials. It cures with atmospheric moisture into a strong, slightly foaming bond line that compensates for small irregularities between dimensionally accurate elements.
- Shear strength of 700 kPa, adhesive strength of 150 kPa
- Minimum mechanical fixing time of 30 minutes
- Final strength after 24 hours
- Thermal conductivity of 0.030–0.035 W/(m·K)
- 750 ml gun-grade aerosol; 500 ml handheld version available
Masonry Adhesive Foam for Blocks, Aerated Concrete and Sills
This masonry adhesive foam bonds stacking blocks, hollow blocks, concrete, aerated concrete, fibre cement, pond edges and window sills or thresholds. Applied with a foam gun via the NBS valve, it is fast and precise to dose. The adhesive is not intended to fill large cavities or strongly uneven surfaces; for structural applications, always follow the requirements and approvals of the building system. Temperature resistance -35 °C to +90 °C, fire class E (EN 13501-1).
