General notes
- Do not add any foreign substances during mixing and application.
- Protect the freshly applied render/plaster from rain so as to avoid among others efflorescence and from too quick dehydration, in order to ensure an optimal hardening.
- Comply with the national guidelines and/or standards (for ex. DIN 18550); if not issued and if necessary, request technical advice.
- 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.
Special notes
- After a sufficient hardening and uniform drying (3 - 4 weeks), all Weber mineral overlay renders (top coats) - range weber.star or weber.top - can be applied.
