Enke Betoncoat 1K Primer is a pore-sealing reactive primer, used in particular as an adhesion primer on mastic asphalt. It is also suitable for mineral substrates where rapid recoating on the same day is required. It forms part of the Enke Betoncoat system for floor surfaces subject to heavy loads.

The 1K primer is used when:

• there are time-critical construction sites,
• The surface is to be coated on the same day,
• or mastic asphalt is present as the substrate.

For traditional mineral substrates with higher requirements in terms of pore sealing or moisture tolerance, however, 2K primers are usually the appropriate choice for the system.

Betoncoat 1K Primer cures very quickly and, at around 20 °C, can be overcoated after just 2–3 hours. This enables short construction times and streamlined workflows – a clear advantage when operations are ongoing or timeframes are tight.

The primer is applied using a lambswool roller. The primer is ready to use and does not need to be mixed.
Coverage is approximately 200–300 g/m², depending on the absorbency and nature of the substrate. The aim is to achieve an even, pore-sealing coat without any puddles forming.

The primer contains solvent-based polyurethane components and is flammable. Good ventilation, the wearing of protective gloves, safety goggles and suitable protective clothing, and keeping the product away from sources of ignition are essential.
The product should not be applied by spraying, but only by rolling. The instructions in the safety data sheet must be followed.
