房间天花板是石膏板，装修人员间接在下面就刷涂料了。请问这样做，和先批 3妹妹的石膏粉再刷涂料的区分大不大？
装修人员曾经把钉子洞用石膏粉涂平了。

石膏板上先批灰后才粉刷，否则不是看到缝隙了？

As long as the ceiling surface is smooth and clean then you can paint directly. you may want to use a primer directly on the plasterboard first before applying the paint.
Also check what kind of plasterboard they use for the ceiling; Generally there are 2 types of plasterboard: straight edge or beveled edge.
Straight edge - typically you add 2-3妹妹 plaster over all the surfaces because square edges don’t usually line up and thats why you need 2-3妹妹 plaster to make a smooth surface.
Beveled edge - the edges are pre-cut. When 2 board edge joing together it forms a recess slot. you can fill that slot easily with filler and then taped it with building paper and get a smooth surface between boards. When the filler is dry you can paint directly.
For ceilings, builder prefer to use beveled edge because its easier - putting plaster on ceiling is difficult and tiring and it drys very slow.
