Description

Monobase is a single-component polymer-based non-combustible cementitious coating which has been developed to utilize advanced polymer technology to combine the strength and toughness of polymer-modified cement with the flexibility of synthetics.

Advantages
  • rior adhesion to various substrates
  • Combines the strength of cement and the flexibility of synthetics
  • Designed to allow minor movements in the substrate without causing cracking in the base coat
  • High flexibility allows for large surface areas to be coated without the need of unwanted control joints
  • Ready to use; just add water
  • Ease of application
Uses

Monobase coating is used as a non-combustible base coat in Durex® EIFS Systems and applicable as indicated in the respective systems specifications.
