Primer concentrate GK5 | blocking ground | TÜV SÜD certified | pretreatment and preparation of the substrate for shielding paints

The primer concentrate GK5 is ideal for pretreating substrates as blocking ground for carbon shielding paints by YSHIELD. It is also a way to save money by avoiding an overuse of expensive shielding paint. TÜV SÜD certified!

No matter which shielding paint and no matter which manufacturer is chosen, the shielding paint and the substrate will inevitably be connected. There are rules of thumb regarding the yield of one liter of shielding paint, even though these can be “very relative”. If the substrate is prepared and as smooth as possible, the given yield is achieved most of the time. However, if the substrate is grainy, rough and with indentations (rough or fine plaster), the shielding paint is strongly put in, the use of paint increases and the yield goes down dramatically (we have already had a 30-50% reduction).

This specially developed, coordinated and high-quality GK5 primer concentrate was specially designed for the requirements of shielding paints on substrates. Firstly, it is an ideal condition to achieve the highest shielding attenuation possible with the shielding paint. However, it is also ideal to help people avoid unnecessarily high shielding costs through an overuse of expensive shielding paint.

This GK5 primer concentrate be used for priming old stable coats and tender, chalky and absorbent substrates. GK5 primer is also ideal for graphite shielding paints if problematic (mineral) coats need to be applied.
