MasterSeal M 686
MasterSeal M 686 is a hand applied rapid curing two component elastomeric polyurea membrane with high chemical and mechanical resistance.
The slight thixotropy of MasterSeal M 686 makes it ideal for the detailing of a variety of concrete waterproofing applications, including around manhole covers and upstands on reservoir roofs, secondary containment, raw water tanks, wastewater and biogas plants, digestors, commercial roofing, podium decks and balconies.
MasterSeal M 686 is applied by hand using a notched trowel or spreader (rubber or steel).

MasterSeal M 686 demonstrates excellent resistance to a range chemicals (tested according EN 13529).
High abrasion and impact resistance. Can be directly exposed to vehicular traffic.
Extraordinary crack-bridging and elastic properties.
Remains elastic even at low temperatures (Class A5 and B4.1 @-10ºC).
