CASEA Bauprotec 850 M – Lightweight Lime Cement Render

Bauprotec 850 M is a factory-produced Lightweight Lime Cement Render, specially designed for machine or hand application produced to EN 998-1: 2010 and is CE Marked.

Bauprotec 850 M is manufactured from a controlled blend of selected aggregates, lightweight aggregates, cement, polymers, and other components, therefore giving a high-quality weather resistant 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.

Bauprotec 850 M is a lightweight render for facades and walls constructed out of low, medium and high-density blockwork besides other masonry substrates. The product’s special composition allows the product to breathe therefore permits constant hygrometric exchange between the substrate and the environment.
