Product usage
Application and installation guidance.
JGN806 works great for patching up concrete surface issues like pits and cracks, prepping areas for carbon fiber or steel reinforcement, and adding protective layers against corrosion on bridges or buildings. It also seals cracks effectively and can decorate or protect concrete exteriors, performing best on clean, dry surfaces but holding up on damp ones too.
Construction Process
Mix A and B in a clean container per the ratio until uniform—use a knife for small batches or a mixer for larger ones. For protection jobs, grind the concrete to expose aggregates and scrape on 2-5mm thick. When repairing defects, chisel out loose parts first, then layer as needed; thin with a bit of primer if desired. For sealing cracks, cut grooves if necessary before filling. It sets strong in 12-24 hours at 25°C, ideal for quick turnarounds.
Why JGN806?
Folks in construction often pick JGN806 because it handles real-site challenges like uneven surfaces or slight moisture without losing grip. Plus, its concrete-like color means repairs blend right in, avoiding that patched-up look on visible areas.
