Polurethane-Polyurea hybrid waterproofing membrane MasterSeal M 860 is a hand applied, solvent free, two component, self levelling, polyurethane -polyuria hybrid based, elastomeric coating.
MasterSeal M 860 is used in a variety of general concrete waterproofing applications including
balconies, terraces, podium decks and car park decks. It is also used in roofing applications where
there is no requirement for a fire retardant system.
MasterSeal M 860 is self levelling and is used on horizontal and near horizontal surfaces.
