Paint concrete prefabricated garage white / light gray / gray?

We are planning a precast concrete garage, which is expected to be delivered with the standard smooth formwork concrete surface. We probably will not order a white exterior plaster. Instead, we have considered painting the concrete ourselves in white, light gray, or gray. Does something like that work on bare concrete? And if it works, does it look reasonably good afterwards? Unfortunately, I have not found any photos of how the surface looks through image searches so far.

Above all, the color of the garage must also match the house!

Yes, absolutely right, that's why I mentioned several colors. As I have seen, there is exterior paint for concrete surfaces, which would probably fit. I would only be very interested in real photos because I can hardly imagine how smooth/rough a shuttering-smooth concrete is, whether it has those characteristic small holes, etc.

We are planning with a precast concrete garage, which will probably be delivered with the standard smooth shuttered concrete surface. We probably will not order a white exterior plaster.

What kind of cheap provider is that who offers a precast concrete garage with an extra charge for finishing – do you have to pick it up yourself too? ... that sounds like a joke to me.

VW sells quite well in Germany, even though the cup holder costs an additional 20 euros and is included with others. I actually find it less important whether the garage costs 38,000 euros and the plaster 2,000 euros, or whether another provider offers the garage for 40,000 euros in total. On the contrary, if it is optional, at least you have an additional choice.

VW sells quite well in Germany, even though the cup holder costs an extra 20 euros and is already included with others.

But not even VW offers the boxes unpainted.
