ᐅ Silicone Resin or Emulsion Paint – Which Is Better for Interior Walls?

We are about to move into our 8-year-old condominium and currently have painting quotes on the table to have the entire interior of the 4.5-room apartment repainted white. The walls have a rough plaster finish and are white in good condition. The paint could probably last another 1-2 years without needing a new coat, but since the apartment will be empty anyway, it would be nice for it to feel "fresher."

Now that we have the quotes from painters, I notice that the cheaper offers usually specify silicone resin paint, while the more expensive ones mostly use interior dispersion paint.

Painting costs, compared to the purchase price of the apartment, are almost negligible, so I don’t want to save in the wrong place. Could someone advise me on which type of paint is best to use for standard interior rooms?

@Scout What you are writing here is simply pure propaganda. Anyone interested can easily find the safety data sheet for Stocolorbasic online. This interior paint, based on dispersion technology, is typical for large projects because painters can buy it in bulk at a low cost, yet it still ensures good application and coverage. This middle-of-the-road interior paint is non-toxic, contains no biocides, is completely safe, and is used on walls in thousands of hospitals, nursing homes, apartment blocks, and office buildings. That is a fact, not fake news.

No, Karsten, not like that! You’re just repeating what your brother said.

The Safety Data Sheet for this paint clearly states:

Contains 1,2-benzisothiazol-3(2H)-one, a mixture of 5-chloro-2-methyl-2H-isothiazol-3-one [EC No. 247-500-7] and 2-methyl-2H-isothiazol-3-one [EC No. 220-239-6] (3:1), 2-methyl-2H-isothiazol-3-one. May cause allergic reactions.

What do you think is the purpose of the isothiazolinone in there? Clearly, only as a biocide! Any objections?

Codecheck comments:
Possible sensitization or allergy potential. Only a low concentration is allowed in the workplace.

Just Google Dr. Wolfgang Plehn from the Federal Institute for Risk Assessment on “Isothiazolinones on the skin and in indoor air – misjudgments and their consequences.”

There it says, for example:

"The Information Association of Dermatological Clinics (IVDK) estimates that 1-2 million people in Germany are sensitized to MIT ▸ According to the Building Trade Association (BGBau), 80 cases of occupational illnesses related to isothiazolinones have been recognized in the last 10 years."

And the data sheet also states:

Contains VOCs (Directive 2010/75/EU) 0.02%, 0.3 g/l.

So volatile organic compounds, meaning: it releases vapors.

At least I would replace “completely” with “supposedly.”

This paint is certainly economical to use, easy to apply, and looks good. But your “harmless” does not apply to everyone.

I don’t think we will agree on this. The UBA apparently considers this preservative harmless, but you and others do not. My wife and I do not have allergies. I don’t feel that these wall paints affect me.

We are now using StoDecolit K 1mm (0.04 inches) interior plaster and the Rapid dispersion paint from Sto. It looks great so far, and I’m curious to see the long-term results.
