Universal Primer 2K is a two-component, polyurethane-based bonding agent suitable for almost all substrates found on site. It is used in conjunction with the Enke liquid polymer systems Enkopur, Enkryl and Enkolan to ensure reliable adhesion to a wide variety of materials such as metals, concrete, cement screed, tiles, bituminous roofing membranes, elastomeric membranes and existing floor coverings.

Universal Primer 2K is the preferred choice when:

• there are different or unknown substrates,
• sensitive substrates such as films or membranes are present (minimal swelling),
• rapid drying and prompt further processing are required,
• or maximum adhesion is required on roofs and balconies.

It covers around 95 per cent of all typical construction site substrates and significantly simplifies the choice of system.

Components A and B are thoroughly mixed to a homogeneous consistency in a mixing ratio of 100 : 60. The ready-to-use mixture is applied to the prepared substrate by rolling or brushing.
Unlike many two-component products, the primer remains usable for several weeks after mixing, provided the container remains sealed airtight. The drying time is approximately 15–60 minutes (depending on temperature).

The consumption is approximately 100–200 g/m² (based on the ready-to-use mixture). The following factors are decisive:

• the roughness and absorbency of the substrate
• Application method (roller or brush)

The aim is to achieve an even, continuous film without any puddles forming.

Universal Primer 2K contains solvents and must not be used indoors. Ensure there is adequate ventilation, keep away from sources of ignition, and wear protective gloves, safety goggles and suitable work clothing.
When handling Component B, the isocyanate warnings must be observed (training is compulsory for commercial use). The information provided in the safety data sheets is binding.
