MS Polymer Waterproofing Coating | Manta MS2024
Manta MS2024 is a liquid waterproofing membrane based on silane-modified polymer (SMP type) and nano-calcium carbonate, which cures with ambient moisture to form a seamless, elastic, impermeable rubber-like barrier. It is VOC-free and solvent-free, self-leveling, and used on roofs, exposed floors, basements, exterior walls, bridges, tunnels and metal surfaces.

Overview
Manta MS2024 is a liquid waterproofing membrane based on silane-modified polymer (SMP type) and nano-calcium carbonate, reinforced with inorganic fillers and functional additives. It cures via ambient moisture to form a seamless, highly elastic and impermeable rubber-like barrier.
The coating is VOC-free and solvent-free, self-leveling with good penetration, and has a rapid, neutral moisture cure. The cured membrane shows good elongation, tensile strength, tear resistance and peel adhesion, and it resists prolonged UV radiation, ozone and salt spray while remaining flexible across a wide temperature range. It bonds to most building substrates; test adhesion on the actual substrate before use.
Compared with Manta HS140, a one-component pure silicone coating with a specified VOC limit, MS2024 is an SMP-based coating listed as VOC-free. Both require a clean, dry substrate. Where the substrate is damp, Manta HP-2K is a two-component system that can be applied to damp substrates.

Applications
- Construction waterproofing and thermal protection: seamless waterproofing and, for light colors, thermal reflection on new and existing roofs, exposed floors, basements, exterior walls, warehouses and water tanks
- Infrastructure and public facilities: bridges, subways, tunnels and highways; because it is solvent-free, also sensitive environments such as archives, libraries, technical rooms and historical heritage sites
- Metal and exterior protection: waterproofing, anti-corrosion and UV shielding for aluminum balconies, window awnings, corrugated metal roofing and storage tanks
- Bonding: adhesive for decorative wall panels
- Detail repair: adhesion to concrete, wood, ceramics, glass and metal, for waterproofing repairs on external surfaces, basements and bathrooms
Application Guidelines
- Substrate: Clean, dry and structurally sound, free of standing water and condensation. The substrate temperature must be at least 3 °C above the dew point; residual moisture can lift the cured membrane.
- Coverage: Apply a minimum of two coats. Ensure application does not exceed a coverage rate of 1.5 gallons per 100 square feet (approx. 6.11 liters per 10 square meters) per coat to ensure proper curing.
- Method (Cross-Hatch): Allow the first coat to cure sufficiently (walkable) before applying the second coat. The second coat must be applied perpendicular (cross-hatch direction) to the first coat.
- Inspection: Ensure all target surfaces are coated evenly and completely, leaving no gaps, pinholes, or blisters.
- Limitations: Not recommended on bituminous membranes (APP/SBS, BUR), where the coating can delaminate, or for areas under permanent ponding water.

Frequently Asked Questions
What coverage rate should be used when applying Manta MS2024?
Apply a minimum of two coats, at no more than 1.5 gallons per 100 square feet (6.11 liters per 10 square meters) per coat so that each coat cures properly. Apply the second coat perpendicular to the first in a cross-hatch direction once the first coat is walkable.
Which substrates does Manta MS2024 bond to?
MS2024 bonds to most building substrates and shows strong adhesion to concrete, wood, ceramics, glass and metal. Test adhesion on the actual substrate before use. It is not recommended on bituminous membranes (APP/SBS, BUR), where the coating can delaminate, or for areas under permanent ponding water.
How fast does Manta MS2024 skin over, and what colors are available?
Tack-free time: Approx. 20-30 minutes, under the test conditions listed in the specifications. MS2024 is available in black, white, gray and blue.
Can I test Manta MS2024 before placing an order?
Yes. Samples are charged. The sample fee includes courier delivery and is deducted from your first formal order. Use Request a Sample and state the quantity and your application. The TDS is on this page; SDS and COA are available on request.
