ᐅ Red lime plaster advantages? Which paint to use and how often to repaint?

Hello everyone,
We are currently in pricing discussions with three general contractors. All three brought up the topic of red lime plaster. I find it hard to follow, as their statements were completely different:
1: "Yes, red lime plaster is great, but so is the Mercedes. It costs about 15,000 euros more."
2: "I would definitely use red lime plaster. It’s definitely worth the additional cost of 5,000 euros."
3: "Red lime plaster is a great option. If you do the painting work yourself and we can agree on a compromise regarding the color, we can replace the red lime plaster one-to-one with cement plaster including painting."
Could the experts here please briefly assess the situation?
Also, I’m wondering which silicate paint should be used. Prices start at around 40 euros for a basic hardware store paint, go up to 80 euros for well-known brands, and over 200 euros for the Knauf option. Is the simplest solution to discuss this with the general contractor or the painter and let them handle the sourcing?
Edit: I realized afterwards that this topic might fit better in the "Masonry / Painting / Plastering / Electrical" subforum and have reposted it there.

Offers 2 and 3 are on par...
Don’t confuse painting work in new construction with a renovation coat in a rental apartment. Thank you for your feedback. Since I am naively calculating only the material costs and the paint and supplies won’t cost more than 5000 euros, I am much more satisfied with offer 3. Due to my profession, I can afford to spend several hours every day on the construction site for a few weeks.

In that case, it works for you if you don’t offset the extra effort, even though you are leaving out a large part of the calculation. However, the main answer to part of your question remains that this plaster will be significantly more expensive, and you have to decide for yourself why or if you want to bear those additional costs.
That said, I understand well that people are willing to put in more effort or pay more if they truly want something.

Yes, I’m definitely quite stuck and was really hoping for confirmation that the added value of the plaster truly justifies the extra effort and isn’t just a marketing gimmick.

@majuhenema – Just a thought. Why? Once the paint is applied, you won’t notice any difference in your house from that expensive material. You enter a house with gypsum plaster and think: phew, there’s no difference. And you paid so much for it.
Lime plasters make sense in heritage buildings. Let’s say a castle or a church needs restoration. Late Middle Ages. The builders back then couldn’t make buildings airtight. It wasn’t possible; they didn’t have the materials yet. The fact that the Romans knew about concrete was forgotten in Northern Europe in the meantime.
If you coat such a masonry from the inside with machine-applied plaster and paint it with Caparol, this happens: moisture enters the wall from the outside during damp weather periods. But it’s blocked from drying to the inside. As a result, the water will cause the plaster to flake off. A typical damage caused when old meets modern. If you use lime plaster and a chalk-based paint instead, the plaster and paint will absorb some moisture but won’t flake. When drier weather or wind comes along, the wall dries out again, as do the plaster and paint, and nothing happens.
Clear? But your house is airtight on the outside and dry inside. So why use this plaster? Ask yourself that objectively. K.

majuhenema5 Apr 2021 10:52Deep down, I also feel that you might be right, especially since a mechanical ventilation system with heat recovery is already planned. We have set a decision deadline until the end of April. Maybe by then, it will click for me. Currently, plastering including paint and decorating is still included in the offer. The lime plaster quote came up spontaneously during our last conversation with the general contractor from Offer 3.
I just wonder why this topic is currently so relevant, even in new builds? Is it simply a hype?
