Mapei Purtop HA Hand-applied Polyurea

Mapei Purtop HA Hand-applied Polyurea

Purtop HA is a two-component, solvent-free, hand-applied polyurea resin designed for waterproofing small to medium-sized patios and flat roofs, as well as for repairing homologous polyurea waterproofing layers. It is characterized by its ability to form a tough, highly elastic, and seamless monolithic waterproof membrane.

Major Applications

• Rooftop and platform waterproofing
• Exterior wall waterproofing
• Basement and garage waterproofing
• Bathroom and wet area waterproofing.

Advantages

• Excellent waterproof performance
• Good weather resistance and durability
• Easy to apply
• Strong adhesion to substrate

Technical Data

Excellent physical properties: tensile strength up to 10 N/mm², tear strength up to 40 N/mm, and elongation at break exceeding 500%. Excellent crack resistance; strong static and dynamic crack bridging ability; maintains its strength even at temperatures below -20°C. Chemical resistance; excellent resistance to alkaline substances and diluted acids. Convenient construction; no reinforcement required, does not increase structural load; workable at room temperature for approximately 20 minutes.

Consumption by Experience

Consumption of  Purtop HA depends on the roughness of the various substrates. The theoretical consumption on a

smooth surface with a substrate temperature of between +15°C and +25°C is 2.6 kg/m² per 2.0 mm of thickness.

If the substrate is rougher or if the application temperature is lower, consumption and the setting and hardening times

increase considerably. For severely damaged substrates, we recommend repairing them with a suitable product

beforehand.
