ᐅ Adhering Brick Slips to Aerated Concrete Blocks

Hello
We built our house using 36.5 cm (14 inches) aerated concrete blocks. Now we want to attach brick slips to the exterior. I have heard many different opinions and now I am unsure what is correct.
One person says that a base coat plaster has to be applied first. Another says that he has been doing this for 30 years and you can stick the slips directly onto the blocks. First bonding mortar, then mesh reinforcement, and then the slips.
I originally planned to glue them onto a lime-cement base coat plaster. Could the plaster fall off because of the weight of the slips?
How did you do it?

I can’t really go into detail because I’m not a fan of facing bricks and haven’t dealt with them much. However, I can maybe clarify where the different opinions about whether something needs to go underneath come from: Brick slips can be applied to various types of building materials. Those who think of brick, pumice, or similar walls with standard-sized bricks and thick mortar joints naturally picture less “flat” wall surfaces. With aerated concrete large blocks laid in thin-bed adhesive, the situation is quite different, which also affects the subsequent steps and the most suitable materials.
