Description

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.
