Fields of application
weber.dur 112 is used for preventive structural fire protection on concrete building parts.
The product corresponds to the recipe mortar according to DIN 4102-4 Part 5.1.4 (5).
With the lime-cement lightweight render, structural elements in existing buildings can be fire-protected, while concrete thicknesses can be significantly reduced in new buildings.
For the rendering on steel structure refer to the national standards (for ex. DIN 4102-4).
As base coat render weber.dur 112 can be coated with the thin-layer mineral top coat render weber.star.
Alternative: weber.dur 112 is also used as a base coat and smooth top coat render in a further working step.
For use indoors and outdoors.

General notes
- Comply with the national guidelines and/or standards (for ex. DIN 18550); if not issued and if necessary, request technical advice.
- Protect fresh render surfaces from direct sunshine, strong winds or moisture.
- The consumption figures mentioned in this document refer to the minimum layer thickness of the render. Due to specific substrates and application variations, the consumption might vary. Exact consumption must be determined on a job site mock-up (trial area).
- Adjacent building parts must be separated from the built-in render system.
- Remove cement laitance (hard sinter skin) with a notched large trowel prior to application of subsequent products.
Special notes
- In case of mechanical application use render machines with the following equipment: special fan for insulating render - screw pump D 4.1 or D 6-3 - hoses of 25 mm diameter and maximal length of 15 meters. For full information request technical advice.
- In case of work interruptions over 15 minutes machine and hoses should be run empty and cleaned.
