Making sure white stays white
Even professionals will be familiar with the experience of painting a wooden substrate white, only for the yellowy brown colour to start showing through later on. Even if you have applied two paint coats. The new SÜDWEST KATIOTECH lacquers put an end to unsightly discolouration. They reliably block ingredients from the substrate and thus ensure perfect coverage. To make sure that white stays white.
A trio for every substrate
Discolouration mainly affects wooden surfaces, but SÜDWEST KATIOTECH lacquers are also ideal for any other substrate that requires excellent adhesion and a versatile appearance, such as plastics or non-ferrous heavy metals. A primer and two finishing lacquers are available.
The primer is suitable for interior and exterior wooden substrates and can also be used as a strong adhesion promoter on plastics or non-ferrous heavy metals indoors. These surfaces can then be overcoated with other finishing lacquers without any discolouration.
Properties
- Primer on a cationic binding agent base for interior and exterior use
- Prevents discolouration caused by soot, grease, nicotine, and wood constituents from showing through
- Excellent adhesive
- For all substrates
- water-based, low-odour and quick-drying
- Container sizes: 750 ml, 2.5 l, 10 l
The matt SÜDWEST KATIOTECH Deckenlack was developed for interior surfaces that are only rarely exposed to mechanical stress, e.g. wooden ceilings or panels, but also any other materials. Designed as a one-pot system, the first coat of the product serves as a primer and the second as a finishing lacquer.
Properties
- One-pot-system
- Prevents discolouration caused by soot, grease, nicotine, and wood constituents from showing through
- Excellent adhesive
- Matt appearance
- For all substrates
- Container size: 2.5 litres
The first choice for surfaces that are subject to mechanical stress or frequent cleaning, e.g. doors or panelling. The lacquer provides a silk gloss, robust surface on almost all substrates. The product is a one-pot system: primer and finishing lacquer can be applied in two coats.

Background information
How does discolouration occur?
The binders in conventional lacquers and paints are alkaline. They dissolve ingredients such as organic wood components, nicotine, or soot from the substrate, which then appear on the surface as unwanted discolouration during the drying process. The process is repeated with the second paint coat and discolouration appears again.
The pH value is the solution
The water-based SÜDWEST KATIOTECH lacquers use cationic binders with positively charged ions. Their pH value is therefore below 7, in the slightly acidic range. As a result, the discolouring ingredients are either not dissolved at all or only slightly and are firmly bound into the first coat of paint during drying. The second paint coat ensures perfect coverage.
