    MasterSeal 550 - An acrylic reinforced, cement-based, flexible waterproof coating


    MasterSeal 550 is a two-component, acrylic modified cement-based coating that requires only on-site mixing forming the ideal product to waterproof and resurface concrete, masonry, and most other construction materials. Simply applied by stiff brush, roller or trowel, it forms a waterproof, flexible coating. 

    MasterSeal 550 provides an effective barrier to waterborne salts and atmospheric gases. Fluid applied, MasterSeal 550 provides a hardwearing, seamless, waterproof membrane for roofs and foundation protection.

    Where is MasterSeal 550 applied?

    • To reface and even out variations in concrete surfaces 
    • As a waterproof lining for water retaining structures like water tanks, pools, reservoires, etc. 
    • For coating seawater channels 
    • Sealing and coating tie bar holes to ensure water tightness 
    • For waterproofing and protection against brackish water 
    • To provide foundation & retaining walls protection 
    • As a waterproof coating for roofs 
    • As a backing to marble and granite to prevent water ingress, and thus alleviate surface staining 
    • To provide protection to concrete surfaces from carbonation and chloride attack 
    • For use on pedestrian walkways in marine areas 

    What are the advantages of MasterSeal 550?

    • A 1mm coating provides anti-carbonation cover equivalent to over 80cm of concrete 
    • Waterproof – resists up to 7 Bars (70 metre head) of pressure 
    • Excellent adhesion – bonds to porous and non-porous surfaces 
    • Flexible 
    • Non-toxic – suitable for contact with potable water 
    • Suitable for light pedestrian traffic 
    • Breathable - whilst repelling water, allows substrate to breathe 
    • High resistance to carbon dioxide and chloride ion diffusion 
    • Unlike conventional coatings, which require a 7-28 day cure of concrete, MasterSeal 550 can be applied to 24 hourold concrete, thereby giving immediate protection​​
