Two-Component Waterproofing Coating | Manta HP-2K
Manta HP-2K is a two-component reactive waterproofing coating that combines high elongation with high tensile strength. It can be applied to damp substrates and is suitable for positive-side and negative-side waterproofing of flat roofs, terraces, basements, foundations, wet rooms and tunnels, on concrete, metals, PVC, existing coatings and bituminous membranes.

Overview
Formulated with proprietary polymer technology, Manta HP-2K is a two-component (A/B) waterproofing system designed to combine high elongation with high tensile strength. The liquid-applied, ambient-curing system forms a continuous watertight barrier and provides high weatherability and durable, long-term substrate protection.
HP-2K overcomes a drawback of polyurethane systems: the sensitivity of their isocyanate component to moisture. It can be applied directly onto damp substrates and is suitable for both positive-side and negative-side waterproofing. Its viscosity can be tailored using DBE to meet specific application requirements.
The one-component coatings Manta HS140 and Manta MS2024 require a dry substrate and are not recommended on bituminous membranes. HP-2K is a two-part reactive system that can be applied to damp substrates and adheres to bituminous membranes.

Applications
- Roofing: flat roofing systems and terraces
- Below grade: basements and foundations
- Wet rooms: kitchens and bathrooms
- Negative-side waterproofing: interior waterproofing of retaining walls and cellars
- Infrastructure: tunneling
Surface Preparation & Application Guidelines
- Substrate Preparation: The substrate must be structurally sound, clean, and entirely free of dust, grease, oil, and other contaminants.
- Mechanical Cleaning: Mechanically remove any friable parts, laitance, or loose particles using a wire brush, scraper, or suitable abrasive method.
- Pot Life Consideration: Due to the system's rapid curing kinetics, Part A and Part B must be thoroughly mixed and applied immediately within its workable pot life.

Frequently Asked Questions
What is the mixing ratio for Manta HP-2K, and how should pot life be managed?
Mix Part A and Part B at A:B = 4:1 (by weight). Because the system cures rapidly, the two parts must be thoroughly mixed and applied immediately within the workable pot life.
How quickly does Manta HP-2K cure?
Tack-free time is < 4 hours (at 25°C). Through-cure time is < 24 hours.
Can Manta HP-2K be applied to damp concrete or on the negative side?
Yes. It can be applied directly onto damp substrates and is suited to both positive-side and negative-side waterproofing, including interior applications on retaining walls and cellars.
Can the viscosity of Manta HP-2K be adjusted?
Yes. Viscosity can be tailored using DBE to meet specific application requirements.
