Sikalastic® M 200 | Polyurethane Base Coat for Sikalastic® Traffic Systems

Sikalastic® M 200 — Moisture-Curing Polyurethane Base Coat Membrane

One-component, moisture-curing polyurethane base coat (formerly MasterSeal® / MSeal M 200) | 5 US gal (18.93 L) pail | Brand: Sika | System: Sikalastic® Traffic 1500 / 2000

Sikalastic® M 200 is the liquid-applied polyurethane base coat membrane used in Sika's Sikalastic® Traffic 1500 and Traffic 2000 deck coating systems. Applied at 25 wet mils (0.64 mm), it forms the waterproofing layer of the assembly beneath the system's wear and top coats, bonding to properly prepared concrete and plywood decks.

Performance Highlights

Typical values from the current Sika Canada Technical Data Sheet. Actual results depend on substrate, preparation, mixing, film build and site conditions — confirm against the current TDS and project specification.

Key Characteristics

• One-component, moisture-curing polyurethane — no on-site mixing of a second component; cures with ambient moisture.
• Base coat of the Sikalastic® Traffic 1500 / 2000 systems — the waterproofing layer beneath the system wear course and topcoat.
• Strong adhesion to prepared substrates — for concrete and plywood decks prepared to the specified profile (minimum ICRI CSP 3 on concrete).
• Two grades — self-levelling for field areas; flash/sloping grade for details, cants and sloped surfaces.
• Formerly MasterSeal® / MSeal M 200 — same product family under the Sika name following Sika's acquisition of MBCC.

Typical Applications

• Balconies, walkways and plaza decks in Sikalastic® pedestrian traffic systems
• Parking structures and ramps as part of the specified Sikalastic® traffic system
• Stadiums, mechanical rooms and commercial deck waterproofing over concrete or plywood

Limitations

• Do not apply to damp surfaces or substrates with moisture content above 4% by mass.
• Ambient and substrate temperature must be between +4 °C and +32 °C (40–90 °F) during application.
• Concrete must be mechanically prepared to a minimum ICRI CSP 3 profile; confirm primer requirements against the system documentation.
• Shelf life: 1 year in unopened 5-gal pails, stored per the TDS.

Health & Safety

Moisture-curing polyurethane — use ventilation and the personal protective equipment listed in the Safety Data Sheet during mixing and application. Keep unopened containers sealed until use and follow the current Sika SDS for handling, storage and disposal.
