NEW UP
As I said I was in work in progress for the work in the cellar .. We almost finished restoring 
I had some material in surplus, and so I decided to create a spray booth 
I created using scrap pieces of wood, metal and plasterboard! 
The orange parts are the simple tape to protect the wires!
Internally we have used glass wool to be glued to the plasterboard, to ensure that the dusts of the paint adhering to the surface and do not flutter on the piece.
The wall behind was made with plasterboard to cover the wall and keep it safe.
If you see before we tried with the spray glue, but it was drunk from plasterboard, then we switched to the option B
Good old silicone
To adhere the glass wool at the side of iron, we have drilled the metal pieces to pass the wires and hold the glass wool anchored on three points
With some mishap and various fix with what I had in the cellar 
We have stretch a braided metal cable to carry the weight of the hanging pieces and so we set like this:
Internally set like this:
And here's the final result:
Aesthetically it's not much, but at a functional level is the best that I could create with what I had .. Cost = 0
I just have to buy two or three aluminum trays to be put on the table and fill them with water, to gather dust that falls while I paint and then periodically change the water and / or trays!
Keep in mind the negligible cost of the trays € 0.30 each one ..
I thought of a vacuum cleaner, but it cost me more and then I live in an apartment building .. I can not take a cab industry in the cellar, otherwise other people cause me problems ..
I Aspect your comments and opinions !!
That's all for now!
