Silicate paint in the bathroom improves the indoor climate

In no other living space there is such a high humidity in phases as in the bathroom, only the kitchen reaches in places at these record levels. Mold prevention is inevitably at the center of our efforts, but a well-balanced indoor climate is also desirable for the personal well-being effect. How does silicate paint in the bathroom contribute to this?

Alkaline and diffusible: This is how the silicate paint in the bath works

Silicate paint comes with a high alkalinity around the pH value of 11, so it is comparable in this sense with soapy water. Mold can hardly thrive in such an environment, moreover, the paint "steals" the water from the fungus.

A silicate coating absorbs water vapor and releases it, again in a dry environment, back into the room air. The necessary for the growth of mold surface moisture is thus reduced to a minimum: bad cards for the mushrooms!

Anyone who now applies the silicate paint on a mineral filler surface, which can absorb a lot of moisture within a short time, has almost won. Because this means that virtually no more water gets into the wall and the insulating effect of the outer walls remains fully intact.

On which substrates can silicate paint in the bathroom be painted?

Silicate paints are only suitable for mineral substrates; they do not last on wallpaper or surfaces saturated with substrate. But if you have a raw lime plaster or lime cement plaster in your bathroom, you are on the safe side.

Gypsum plaster is not suitable as a substrate for silicate paint, in addition, this material does not tolerate moisture. Your wall should have no gypsum-based putty points for a silicate coating.

Preparing for a bath painting with silicate paint

  • Mix a color of your choice with special tinting concentrates containing alkali-resistant pigments.
  • If your plaster sand or something porous, a consolidation with diluted water glass helps. Under no circumstances use a plastic base!
  • If your paint is too thick, dilute it with potassium water glass.
  • Cover all glass surfaces, tiles and ceramic elements with foil carefully, because silicate paint splashes will etch these surfaces.
  • Wear protective gloves and paint safety goggles when painting.

Tips & Tricks

Always work with silicate paint wet in wet, otherwise you risk staining and streaking! For larger areas, it is worthwhile to strike as a couple.
