CASEA Bauprocalc KAP 830 – Hydraulic Lime Based Render is a factory produced hydraulic hardening render/plaster based on lime, specially designed for hand and machine application produced to DIN EN 998-1: 2003. It is manufactured from a controlled blend of selected aggregates, hydraulic and building lime to EN 459-1 and other components to give a high quality rendering product which is suitable for use in external rendering and internal plastering. The unique properties of this product makes it suitable for application on low, medium and high density substrates.


  • High water vapour permeability (breathability).
  • Machine or hand application.
  • Suitable for external and internal use.
  • Sustainable.
  • Application up to 20 mm.


A hydraulic hardening render/plaster based on lime for walls constructed out of low, medium and high density blockwork and any other masonry substrate. The product’s special composition allows the product to breathe and also permits constant hygrometric exchange between the substrate and the environment.
