Well I will recommend you should not even try it again.

I do not want any answer from you anytime.

Dear Yngve Kjell Alvarsson,

Yes. It’s possible. I have seen couple of my Indian contractor friend develop a compact wet concrete with a light Roller.

Using vibratory screeds with a light rollar Smooth consolidate & finish fresh concrete surfaces in one step can be done. Roller screeds and vibrating screeds help concrete contractors achieve a quality slab without the bending. The evolution of a concrete contractor starts with casting aside the hand-held striker, standing up straight and taking hold of a hand-held vibratory screed. Vibratory screeds have a relatively low entry price, allowing contractors to see a quick return on their investments when you consider the physical advantages to workers, the speed in which one machine can perform screeding and vibrating, and the quality of the finished product. A roller screed's lack of vibration makes it ideal for pervious concrete, sloped projects like driveways and sidewalks, and inclines. It's especially productive on projects where you're laying concrete in strips.

Hope it help you out.
