In no other living space does the humidity in the room be as high as in the bathroom, only the kitchen reaches these record values in places. 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: How the silicate paint in the bath works
Silicate paint comes with a high alkalinity around the pH value of 11, so in this sense it is comparable to soapsuds. Mold can hardly thrive in such an environment, also the paint "steals" the water to the mushroom.
A silicate coating absorbs water vapor and, in a dry environment, releases it 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 be painted in the bathroom?
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 for a silicate painting.
Preparing for a bath painting with silicate paint
- Mix a shade of your choice with special tinting concentrates containing alkali-resistant pigments.
- If your plaster is sanding or slightly porous, consolidate with diluted water glass. Under no circumstances use a plastic base!
- If your paint is too thick, dilute with potassium water glass.
- Carefully cover all glass surfaces, tiles and ceramic elements with foil, as silicate paint splashes will etch these surfaces. Schutz For protection, put on protective gloves and wear protective goggles.
- Tips & TricksWork with Silikatfarbe always wet in wet, otherwise you risk staining and banding! For larger areas, it is worthwhile to strike as a couple.
