Water-based Flexible Decorative Coating (EN1504-2)

Overview

Flexcrete's Monodex Ultra is a decorative, anti-carbonation masonry coating to protect external walls against carbonation and water ingress. 10 year system.Monodex Ultra is a technically advanced, minimal VOC, water-based decorative coating which protects against carbonation and water ingress without entrapping moisture. It is fast drying for year round use externally with excellent fire performance characteristics for internal use. Monodex Ultra prevents water ingress and resists the growth of mould and fungi, making it the ideal low cost coating for new build and maintenance projects.

Monodex Ultra is a one component, decorative coating which offers an economic solution for the protection of buildings and other structures with a service life up to 10 years. To inhibit the growth of mould and lichen, it contains an active biocide which is retained in-film. Elastomeric properties permit substrate movement and bridging of hairline cracks. Adhesion is excellent to mineral substrates and other commonly encountered building materials.

Monodex Ultra is cost effective for internal use and for the external decorative protection of facades, soffits and the elevations of structures in temperate and tropical climates. Monodex Ultra can be applied using Graco Pumps (see the  Airless Spraying of Decorative Protective Coatings Membranes Graco Pumps).
