    MasterSeal 541 - An acrylic reinforced, cementitious, flexible waterproof coating


    MasterSeal 541 is a two-component, acrylic modified, cementitious coating that requires only on-site mixing to form the ideal product to waterproof and re-surface concrete, masonry, and most other construction materials.

    Where is MasterSeal 541 applied?

    • To reface and even out variations in concrete surfaces
    • As a waterproof lining for water retaining structures like water tanks, pools and reservoirs. 
    • For coating seawater channels
    • Sealing and coating tie bar holes to ensure water tightness 
    • For waterproofing and protection against brackish water 
    • To provide foundation protection 
    • 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 541?

    • Excellent adhesion – bonds to porous and non-porous surfaces  Slight flexibility
    • Suitable for light pedestrian traffic
    • Breathable – whilst repelling water, allows substrate to breathe
    • Slurry or trowellable consistency; application is still possible by spray. 
    • Unlike conventional coatings, which require a 7-28 day cure of concrete, MasterSeal 541 can be applied to 24 hour-old concrete, thereby giving immediate protection
