    MasterProtect 320

    Anti-carbonation coating with acrylic polymers

    Preventing the degradation of concrete and the corrosion of embedded steel reinforcement is an ongoing concern, particularly for structures where preserving aesthetics matters. Protecting concrete against weathering and pollution has never been easier, thanks to MasterProtect 320 – a one-part, ready-to-use, water-based coating formulated from a blend of high-performance acrylic polymer emulsion with pigments and fine fillers. MasterProtect 320 gives excellent protection against carbonation while remaining water-vapour permeable.

    Where to use MasterProtect 320?

    The coating is available in many colours, and provides a protective and decorative finish for exterior and interior use on concrete and other surfaces. It can be used for high-build applications and offers excellent adhesion to concrete substrates. 

    • ​Integral finish for the repair and protection of reinforced concrete
    • Smooth matte finish for new and refurbished buildings
    • Aesthetic final coating for a uniform appearance

    What makes MasterProtect 320 different?

    MasterProtect 320 has very good resistance against saponification and can be applied on almost all substrates without any primer. It forms a strong coating, so can be cleaned by steam or even high water pressure without damage. MasterProtect 320 maintains an excellent bond to the substrate even after undergoing many freeze-thaw cycles.

    Owners will benefit from fewer repair cycles during the lifetime of a structure by using the Master Builders Solutions repair system: 
    • ​MasterEmaco – repair morta​rs
    • MasterProtect – concrete protection

    MasterProtect 320 provides long-term aesthetic protection and longer maintenance cycles, delaying concrete deterioration considerably and helping to reduce operational downtime and overall structural maintenance costs. Its performance is proven by full CE certification in compliance with EN 1504-2 and additional non-mandatory tests.
