    ​SikaTop®-586 Seal (formerly known as MasterSeal® 586)

    Smooth-finish waterproof render for internal and external use on concrete and masonry  

    ​Approved under regulation 31 of the Water Supply (Water Quality) regulations 2000

    Any surface waterproofing system coming into contact with potable water has to not only deliver on performance but meet the right regulations, too.  MasterSeal 586 render has been developed to provide an attractive waterproof finish that protects both the structure and potable water, when needed.

    Where to use MasterSeal 586?

    MasterSeal 586 provides interior and exterior waterproofing for concrete and masonry, above and below ground, where a smooth or textured finish is required. Typical applications include:
    • ​Water reservoirs
    • Tunnels
    • Walls and floors of basements and showers
    • External renders for structures in a harsh-weather environment
    • Blowhole/pore filler

    How to use MasterSeal 586?

    Mix with clean water or a MasterSeal 600 / water blend to a plaster consistency for a waterproof render/fairing coat. MasterSeal 586 is suitable for trowel application in layers of 3mm to 6mm.

    What makes MasterSeal 586 different?

    Solvent-free MasterSeal 586 offers complete waterproofing with a decorative finish. Cement-based for extreme durability, it can withstand both positive and negative pressure. MasterSeal 586 keeps its aesthetic appearance with high-pressure water or steam cleaning.
