About the product
Receive the railing and resume work in minutes
Kerakoll Prestocem ECO is an eco-friendly thixotropic mineral mortar with ultra-fast setting and hardening, specifically formulated for high-strength fixings. It is not a surface repair mortar: it is the product used for receiving and anchoring elements — railings, frames, brackets, corrugated pipes, electrical boxes — when you cannot wait hours for it to harden.
THIXOTROPIC: NON-SAGGING: this is what allows an element to be received vertically or overhead without the mortar falling out of the hole while setting. A conventional mortar would require shoring.
Why choose Prestocem ECO
- ✓ Ultra-fast setting: express commissioning, without immobilizing the work area.
- ✓ High mechanical strength for light structural anchors and fixings.
- ✓ Water and frost resistant, making it suitable for exposed outdoor fixings.
- ✓ Thixotropic: remains in the void in vertical applications without the need for formwork.
- ✓ Eco-friendly and formulated for GreenBuilding.
- ✓ Two formats: 25 kg bag for construction sites and 5 kg box for occasional jobs.
