Usage Instructions

Apply Bostik H785 adhesive in a V-shaped pattern, with the lines running vertically and spaced 10-20cm apart. Place the material in position and press firmly to achieve a minimum adhesive thickness of 2-3mm between the material and the surface. Avoid applying adhesive in circular dots. Due to its high initial strength, additional support during the curing process is often unnecessary. For any inquiries, please contact Hitta’s technical support department.


  • Not suitable for PE, PP, PC, PMMA, PTFE, soft plastic, neoprene, and bitumen substrates.
  • Not recommended for continuous water immersion.
  • Not suitable for use in dynamic joints.

Surface Preparation

Operating temperature: +5°C to +40°C (applicable to both the environment and the substrate). Due to the structure of Bostik H785 NO MORE NAILS HIGH TACK, we recommend using a professional caulking gun with precise drive and a V-shaped nozzle. All substrate surfaces must be firm, clean, free from oil or grease, and dust-free. Cleaning the surface prior to adhesive application is advisable. Bostik H785 adheres well without the need for primer on most non-porous surfaces. Porous surfaces should be pre-treated with a primer. Always perform an adhesion test before application.


When unopened and stored in its original packaging within a temperature range of +5°C to +25°C, the shelf life of the product is up to 18 months from the date of manufacture. Store in a dry place.
