Mapei Purtop 200

Mapei Purtop 200

Purtop 200 is a two-component, solvent-free, pure polyurea-based waterproof membrane suitable for manual application. It is primarily used for waterproofing terraces, flat roofs, and other areas, and can also be used to repair surfaces with existing polyurea waterproofing layers. This product boasts excellent elasticity and tear strength, curing to form a seamless, highly resilient waterproof membrane that can adapt to various geometries without cracking.

Major Applications

• Waterproofing for areas such as terraces and flat roofs
• Repairing surfaces with existing polyurea or pure polyurea waterproofing layers
• Forming a seamless, highly elastic waterproof membrane on substrates of various geometries
• For applications requiring high elasticity, high tear strength, and crack bridging capabilities
• Complies with EN 1504-2 standards and can be used in concrete structure protection systems

Advantages

• Elongation at break > 500% (ISO 37 standard)
• Excellent static and dynamic crack bridging ability, effective even at low temperatures
• Good acid and alkali resistance
• No additional reinforcement required, reducing structural load

Technical Data

Performance (1.5 mm thickness)

Mechanical properties after 7 days at +23°C:

- Tensile strength (ISO 37): > 4.5 N/mm

- Elongation at break (ISO 37): > 500%

- Tear strength (ISO 34-1): > 30 N/mm

Hardness (DIN 53505): Shore A = 60

Watertightness (EN 1928, Method A): No water leakage

Consumption by Experience

The dosage of Purtop 200 depends on the roughness of the substrate. For smooth surfaces with a substrate temperature between +15°C and +25°C, the theoretical dosage is 2.5 kg/m² per 1.5 mm thickness.

If the substrate is rougher, the dosage will increase. If the substrate is damaged, we recommend using a suitable repair product beforehand.
