Hello!!
I’d say it’s partly yes, partly no.. Here’s some info about primers.
Primarily, a primer is used to provide better adhesion, meaning the product you apply after the primer will stick better.
However, if you want to be 100% sure, there are also special adhesion primers made specifically for silicate paints. I believe the company Sto also supplies those; it doesn’t hurt to ask.
Regards.

Hey Schakal, where did you hear that primer acts as a bonding agent?
This is actually a primer that stabilizes and hardens the substrate, and if properly diluted, it also regulates the absorbency.
If applied on a substrate with low absorbency, like drywall or plaster without surface preparation, and the primer remains on the surface or is absorbed too little, creating glossy spots, you actually achieve the opposite—a reduction in adhesion.
By the way, what is your profession, that you recommend and spread such nonsense?

If the primer remains on the surface of a weakly absorbent substrate, like drywall or unpainted plaster, and is absorbed too little, causing shiny spots to form, you actually get the opposite effect—a reduction in adhesion. What do you do for a living that you recommend and spread such nonsense?100% agreement
Regarding the advice to paint walls with water, I can only say that I have never heard such nonsense. Everyone is happy when the walls are dry.

And now to you, Meier!!
But before I start, some information for you:
What I do professionally and so on is none of your business, that should be clear. If you want to ask me something or correct me, I have no problem with that. Maybe everyone can be wrong sometimes, or, as you wrote, well, that’s not to my liking.
Sure, I could have extended my feedback and explained it in more detail, but that wasn’t the point.
But now back to the other point:
Do you actually know that there are tons of products, especially for primers and bonding agents?
There are even some that combine both, just so you know.

Primer
A primer is used to prepare and seal substrates. It is applied indoors and outdoors before applying new coatings, plasters, or tiles on walls and floors.
Primers are available in solvent-free (LF) and solvent-based (LH) versions. Solvent-based primers should only be used outdoors because the smell indoors is very strong. For indoor use, always choose solvent-free primer. Primers have two functions:
1. To stabilize crumbly or chalky substrates, and
2. To create a bonding layer between the substrate and the subsequent coating.
Best regards.

Most of Schwarzmeier’s posts are like that. Apparently, he needs to release some aggression here. He rarely contributes anything productive. It’s unfortunate, but I guess there have to be people like that. Just put him on your ignore list. He really doesn’t deserve any more attention.
Depending on the type, primer does not prevent breathability. Although breathability is somewhat of a complex topic anyway. Just because a wall has some ability to “breathe” doesn’t mean it actually does.
A wall should be able to absorb and release moisture to a certain extent in order to balance fluctuations. Nothing more. Most primers do not prevent this.
Not all primers consolidate the surface, but all of them “equalize” the properties between different materials, for example, gypsum board and filler joint.
It’s best to contact Sto directly; they can provide precise information on which primer is suitable for a specific case.
