Description :

Two-component polyurea-based membrane applied manually for waterproofing roofs

Advantages :

Purtop 200 bonds extremely firmly to various types of substrate, if treated with a suitable primer beforehand,
and, once fully cured, forms a strong, seamless elastic membrane.
Purtop 200 offers the following advantages:

• excellent tear strength;
• high static and dynamic crack-bridging capacity, including at low temperatures;
• elongation properties above 500% (ISO 37);
• excellent resistance to alkalis and diluted acids;
• no strengthening reinforcement required;
• does not form overloads on load-bearing structures.

Technical Characteristics :

Purtop 200 is a two-component, solvent-free, pure polyurea-based formulate according to a formula developed in the MAPEI R&D laboratories. The product is applied manually and has a workability time of around 25 minutes.
Apply Purtop 200 in layers at least 1.5 mm thick. Once fully cured, thanks to its high tensile strength, tear strength and crack-bridging capacity (including at low temperatures), Purtop 200 forms a seamless, waterproof coating which adapts to substrates with any geometric form without cracking.
Purtop 200 meets the requirements of EN 1504-9 (“Products and systems for the protection and repair of
concrete structures. Definitions, requirements, quality control and evaluation of conformity. General
principles for the use of products and systems”) and the requirements of EN 1504-2 coating (C) according to PI,
MC, PR, RC and IR principles (“Surface protection systems for concrete”).
