Class PUX-520 – 2K Moisture-Barrier Polyurethane Floor Primer

CLASS PUX-520

Two-component, polyurethane-based primer developed for dry and damp surfaces.


Description

Application Areas

  • In polyurethane and epoxy flooring systems
  • As a primer on metal and similar surfaces.
  • In polyurea, polyurethane, and similar insulation systems.

Application Information

The packaging, kept at room temperature (+15°C to +25°C) for 24 hours, should be opened and mixed until a homogeneous consistency is achieved. The mixing process must be carried out using a low-speed mixer with a suitable mixing paddle. CLASS PUX-520 is applied homogeneously onto the surface using a fine-toothed trowel, short-pile roller, or brush, while monitoring material consumption. The material must be protected against water, rain, external environmental factors, and mechanical stress until it cures. It should be taken into account that curing times may shorten in hot weather and extend in cold weather.

Consumption

Depending on the surface condition; factors such as substrate porosity and absorbency may increase consumption. A preliminary test on the application substrate is recommended to verify consumption. Theoretical consumption as a primer: 0.300 kg/m² – 0.600 kg/m².

Packaging

In 20 kg sets (A: 15 kg + B: 5 kg) in tin pails
