    Sikalastic® M 800 (formerly known as MasterSeal® M 800) - Spray applied polyurea/polyurethane waterproofing membrane

    How does MasterSeal M 800 work?

    MasterSeal M 800 is a solvent free, two component waterproofing membrane. Due to its fast cure speed it can only be applied by special, two component spray equipment.

    MasterSeal M 800 is intended for use in general waterproofing applications such as car park decks, podium decks and cut and cover tunneling.

    Using the appropriate primer, MasterSeal M 800 can be applied to most substrates including concrete, galvanized steel, aluminum, UPVC, glass reinforced polyester etc.

    What makes MasterSeal M 800 a unique solution?

    Low tensile strength, fast cure spray membrane with exceptional crack bridging abilities.
