Fill Cracks and Holes with Super Glue and Granulate
Super glue alone bonds two matching surfaces. When material is missing, you need a filler. With granulate and low-viscosity glue, you can rebuild the area in minutes.
How the 2K system works
The granulate readily absorbs the low-viscosity glue. As it cures, the granulate and adhesive form a solid compound known as the granulate matrix effect. The repaired area is waterproof, heat-resistant and resistant to chemicals.
Four-step guide
- Prepare. Clean and dry the area. Remove any loose fragments. Cover the back of a hole with adhesive tape to stop the granulate falling through.
- Add granulate. Fill the crack, hole or gap to a maximum depth of 10 mm.
- Apply glue. Apply the super glue precisely to the granulate. It soaks in and cures in seconds. A little heat is generated in the process.
- Finish. Build up additional layers for deeper areas. Then sand, drill and paint as needed.

The granulate usually runs out before the glue. It is available separately and works with any low-viscosity super glue.
Frequently asked questions
Can super glue fill holes?
Not on its own: super glue needs two closely fitting surfaces. Combined with filler granulate, it forms a solid mass that fills holes and cracks.
How thick can the layer be?
Up to 10 mm per application. Fill deeper areas in several layers.
Can I drill into the repaired area?
Yes. The cured compound can be sanded, drilled and painted.
