Do you still need to brush latex paint after decorating the ceiling?

Latex paint can be brushed or not. If you brush it, the surface will be smoother and feel better, but few people will stare at the ceiling of the house, so I think it doesn't matter if you don't brush it. Latex paint is more expensive. If the workers can't brush it well, it's not worth the candle. I don't think it matters if the walls should be painted. The landlord decides for himself.
