CASEA Bauprocalc 830 – Hydraulic Lime Based Render
CASEA Bauprocalc 830 is a CE-marked, 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 that is suitable for use in external rendering and internal plastering. The unique properties of this render make it suitable for application on low, medium, and high-density substrates, for the renovation of old / listed buildings and ecological new builds.
CASEA Bauprocalc 830 contributes to a healthy internal atmosphere. It’s an excellent alternative to plasters containing gypsum or patent types of cement which have reduced vapour-permeable qualities. It’s ideal for kitchens, bathrooms, and other rooms where high humidity levels are expected. It is manufactured from a controlled blend of selected aggregates, hydraulic and building lime to EN 459-1 and other components to high-quality rendering product which is suitable for use in external rendering and internal plastering. The unique properties of this render make it suitable for application on low, medium and high-density substrates, for the renovation of old /listed buildings and ecological new builds. CASEA Bauporcalc 830 hydraulic lime-based render, produces a mortar that is softer than cement mortar.
After the initial set, stability and strength gradually build up over time; allowing enough flexibility to cope with minor settlement or movement in the building during this period, thereby reducing the risk of cracking. Good vapour permeability performance allows an unhindered transference of excess internal moisture through the building to the outside, thereby contributing significantly to a balanced and healthy internal atmosphere.
