Grünwalder 2K primer - flood resistant

If you need a painting set, you can >>>CLICK HERE<<< to order our Lion Color Painting Set (X300). This was specially developed for the paints and varnishes from Farben Löwe.

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

The name itself suggests that the finished paint consists of 2 different components. It is a so-called base varnish (varnish, paint, primer) and the matching hardener. To ensure trouble-free processing of a 2-component paint, there are a few things to consider. The most important data about the paint is always included in the description of the paint. These are the following points:

• Which hardener belongs to the paint
• Mixing ratio
• Processing viscosity
• Dilution
• Pot life
• Processing time
• Processing type (application)
• Processing conditions

These points in detail:

• Which hardener belongs to the paint?

In the description of the paint (usually even on the paint can) the exact name of the hardener that matches the paint is always stated. Please never use another hardener.

• Mixing ratio

The two components, i.e. paint and hardener, are mixed together in a certain ratio immediately before processing. For our paints the ratio is 5:1 (by volume/liters). This means that 5 parts varnish and 1 part hardener are measured and mixed using a measuring cup. Only as much paint should be mixed as is necessary for the work process. 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

The 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 type of processing (brushing, spraying, rolling, pouring, dipping), it may be necessary to change the viscosity, i.e. to add some thinner. As a rule, the dilution addition is between 1% and 20%.

• Dilution

Just like with hardener, it is important to use the correct dilution. This is also stated in the description of the paint and usually on the paint can.

• Pot life

Pot life is the length of time that reactive materials can be processed, e.g.b Varnishes It is the time between mixing a multi-component substance and the end of its processability, so to speak the time period in which the substance can still be "taken out of the pot" and processed. The end of the pot life is usually indicated by a significant increase in viscosity, which prevents further processing.

• 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 because the necessary chemical reaction cannot take place. Even a short-term cooler temperature during curing can lead to problems.
