MASTERSEAL M689

MasterSeal M 869 is a solvent free, self leveling two-component polyurethane membrane. It is applied normally as waterproofing membrane or  on other Masterseal polyurethane waterproofing membranes as a wear coat. MasterSeal M 869 is primarily intended for use in the car park deck Masterseal waterproofing systems.

• Spray delivered and ultra-fast curing: enables easy application to form a monolithic waterproofing membrane on simple and complex surfaces.
• Rapid curing
• Continuous membrane: monolithic – no laps, welds or seams
• Excellent chemical resistance.
• Waterproof and resistant to standing water.
• Fully bonded to substrate: can be applied to a wide range of substrates with the appropriate primer.
• High water vapour permeability: low risk of blistering.
• High resistance to carbon dioxide diffusion: Protects concrete from rebar corrosion.
• High abrasion and impact resistance: Withstand mechanical traffic.
• High elasticity and crack bridging capability: o Remains elastic at low temperatures; Tg approx. – 45°C o High durability and protection with reduced cracking due to embrittlement
• Thermoset – does not soften at high temperatures
• Resistance to root penetration

MasterSeal M 869 can be used in MasterSeal 2263 and MasterSeal 2264 car park systems meeting the specifications of German standard DIN V18026 type OS11 for indoor and outdoor use. Using the appropriate MasterSeal P primer, MasterSeal M 869 can be applied to most substrates including concrete, steel, cement screed, glass, and reinforced polyester. MasterSeal M 869 is the multipurpose coat for parking deck systems for use indoor and outdoor
