Remmers MB 2K – Multi-Functional Waterproofing

Flexible, Crack-Bridging, and Bitumen-Free Waterproofing for Structural Protection. Remmers MB 2K is a high-performance, two-component, polymer-modified waterproofing compound designed for versatile applications in both new construction and refurbishment projects. Combining the strengths of flexible mineral seal slurries and bituminous thick coatings, MB 2K delivers long-lasting, crack-bridging protection that meets modern waterproofing standards—without the use of bitumen.. Key Features & Benefits. Multi-Functional Application: Waterproofs basements, foundations, floor slabs, plinths, balconies, and more.. Crack-Bridging Capability: Bridges cracks ≥ 3 mm for reliable substrate protection.. Rapid Drying: Full drying in 8–24 hours depending on conditions—speeds up construction timelines.. High Adhesion Strength: Bonds to mineral and aged bitumen substrates (subject to condition and preparation).. Flexible Application: Apply by brush, trowel, or spray to suit site conditions and surface profiles.. Solvent-Free & Low VOC: Safer for applicators and environmentally responsible.. Short-Term UV Resistance: Withstands temporary exposure during construction—final finish recommended.. Tested to DIN EN 14891: Suitable for liquid-applied waterproofing under ceramic finishes.. Application Areas. New build waterproofing (walls, slabs, and foundations). Retrofit waterproofing (WTA-compliant). Basement walls and exterior plinths. Waterproofing beneath or behind walls. Sealing pipe penetrations and movement joints. Adhesive for perimeter insulation boards. Connecting to watertight concrete components. Technical Specifications. Composition: Polymer binder, cement, mineral fillers, additives. Density: Approx. 1.15 kg/dm³ (mixed). Drying Time: 8 hours at 23°C / 50% RH; up to 24 hours at 5°C.
