The application of 2K or 2-component paint is explained very simply and quickly.

The name alone says that the finished paint consists of 2 different components. It is a so-called master paint (varnish, paint, primer) and the matching hardener. There are a few things to consider for problem-free processing of a 2-component paint. The description of the paint always contains the most important data about the paint. These are the following points:

• Which hardener goes with the paint
• Mixing ratio
• Processing viscosity
• dilution
• pot life
• Processing time
• Type of processing (application)
• Processing conditions

These points in detail:

• Which hardener goes with the paint?

In the description of the paint (usually even on the paint can), the exact name of the hardener that goes with the paint is always given. Please never use any other hardener.

• Mixing ratio

The two components, i.e. paint and hardener, are mixed together in a specific ratio directly before processing. With our paints, the ratio is 5:1 (by volume/litres). This means that 5 parts of paint and 1 part of hardener are measured and mixed in a measuring cup. Only as much paint should be mixed as is necessary for the work step. Once the hardener has been added, the hardening process can no longer be reversed. Stir the mixture well for at least 1 minute.

• Processing viscosity

Viscosity is a measure of the viscosity. The higher the viscosity, the thicker (less flowable) the liquid is, the lower the viscosity, the thinner (more flowable) it is. Depending on the type of paint and processing (painting, spraying, rolling, pouring, dipping) it may be necessary to change the viscosity, i.e. to add a little thinner. Typically, the addition of dilution is between 1% and 20%.

• dilution

Just like with the hardener, it is important to use the right thinner. This is also given in the description of the paint and usually on the paint can.

• pot life

The pot life is understood as the duration of the processability of reactive materials, e.g. paints.It is therefore the time between the mixing of a multi-component substance and the end of its processability, the period of time, so to speak, in which the substance can still be "taken out of the pot" and processed Processing prevented.

• Processing time

In addition to the pot life, some materials also have a processing time. Optimum processing is only possible during this time. After that, the workability and the painting result deteriorate, even if the paint is still liquid and no change can be seen. So please only mix as much paint as you can use in one go.

• Processing type, application

Lacquers and paints are always developed for specific applications. Therefore there are differences in the processing method. For example, spray paint can usually not be applied with a brush, or only very poorly, because it dries far too quickly. With a paint that is suitable for painting, the drying time is much longer, which is why, for example, dust can fall onto the fresh surface longer during the drying time. It is therefore important to pay attention to the type of processing specified for a paint, varnish or primer.

• Processing conditions

The processing and especially the drying of 2-component paints should not take place below 18°C. This information refers to the paint material, substrate and room temperature during processing and the subsequent drying and curing time of 7 days. Temperatures that are too low lead to drying and hardening problems, since the necessary chemical reaction cannot take place. A brief cooler temperature during curing can also lead to problems.
