Hello everyone,
I have a detached double garage with a flat roof (concrete slab with 2cm (1 inch) PUR insulation and plastic waterproofing). The walls are made of 24cm (9.5 inches) Poroton bricks / hollow clay blocks (with a bulk density of 0.8 or 0.9).
What base plaster would you recommend for the exterior and interior? The suppliers suggested KNAUF LUP 222 (lightweight lime-cement plaster). What are your thoughts on this? Would you rather avoid using the lightweight aggregate?

Do I understand correctly that LUP222 is not recommended? No, you asked:

What would you recommend as a base coat for exterior and interior? And I said:

I cannot specifically recommend any exterior plaster product. Should I have clearly stated that I also cannot specifically advise against any exterior plaster product?
I am not a professional building materials salesperson, so I am not knowledgeable about comparing exterior plaster products A, B, ... Y or Z.
Therefore, my recommendation only referred to the interior plaster: to simply omit it in a garage, because from my perspective, interior plaster in garages or utility basements is entirely dispensable. I have lived for half a century without an "appendix" and have had no problems with garages without plaster and utility basements without screed. My best garage (made of pumice blocks without interior plaster) was even literally "without a floor." While promoting such voluntary austerity to this extent might be excessive, I am happy to confirm from long personal experience that you do not really suffer any disadvantage here. Cars are architecturally not demanding, after all.

Yes, something has to be applied because slots, sockets, etc., also need to be covered. Slots are filled with filler, and switches and sockets are also available as surface-mounted.

maybe my wife should decide now and then or take over the decisions from me 😉you now want to bother your wife with this, to put it politely, "First World Problem." We were actually talking about two questions: 1. whether a certain product, plaster XYZ, is the right choice; and 2. whether it is also suitable for interior use.Regarding 1., I would tell you myself, as someone who is only a semi-expert in understanding women, that this typically is not a core interest area for women, to be familiar with building plasters. Foundation or camouflage makeup is really not comparable.
Regarding 2., the conclusion "give up all hope that anyone would seriously consider plastering the inside of a garage" automatically (and I thought this was self-evident until now) also implies "never risk your marital harmony by nagging your beloved about such trivial matters."
For these two reasons, in my opinion, it is a major sympathy killer to delegate this to your wife. Women have a fine sense for detecting the underlying message: "Honey, I’m brooding over something completely trivial, could you take it off my hands?" — and they can take that very badly.

I don’t think there’s anything to add. Inside my garage, there is a beautiful retaining wall made of L-shaped concrete blocks, which hold back the slope next to it. I would never even consider plastering that wall.
However, if the original poster really has a lot of money to spare: insulating plaster is more suitable for living spaces and damp rooms. It also provides some insulation and can be used universally in all interior rooms. I applied it throughout my entire house interior. For a garage, it’s a bit like using a sledgehammer to crack a nut. And it’s definitely not suitable for exterior use.
