Important Information About the 30-Second Grab Time
The “30-second grab” means the adhesive will hold surfaces in place within half a minute,
but full curing takes 24–48 hours.
For best results and long-lasting adhesion, do not disturb the bonded surfaces during this period.
Use clamps or support for heavy items or vertical applications.
Suitable for:
Wood, stone, metal, foam materials, concrete, ceramic, marble, drywall, tiles, bathroom fixtures, mirrors –
perfect for any application where a clean, invisible bond is needed.
Instructions for Use
Surface Preparation:
Make sure surfaces are clean, dry and free of dust, grease, and oil. Slightly damp surfaces are acceptable.
1. Load
Cut off the tip of the cartridge above the screw thread. Attach the nozzle and cut to desired bead size. Insert the cartridge into a standard caulking gun.
2. Apply
Apply adhesive to one surface in a zig-zag pattern. For uneven surfaces, use enough adhesive to fill gaps. Best results are achieved above 5 °C (41 °F).
3. Press
Within 5 minutes, press surfaces together and hold for 20–60 seconds. For heavier materials, use clamps or temporary support.
Full cure in 24–48 hours.
