ᐅ Painting Maxit facade render in white?

Hello, the final coat of exterior plaster has just been applied at our place! It is from the manufacturer Maxit, in white. So now I’m wondering how many times it needs to be painted. The plastering company says once is enough if it’s white, but a painter friend says that new plaster always needs two coats. What do you think? Thanks a lot for your opinions!

We have the same situation. I don’t know the brand. But it was said that if the color is already mixed into the plaster, we only need to paint once. Otherwise, it wouldn’t make sense. Just be careful to get the exact same shade.
