modificato la cc addensandola( e' diventata quasi pastosa).
Il primo distributore di Roma mi disse di usare l'airless(sul prospetto di allora veniva consigliato).
Dalle discussioni passate rilevo che quasi tutti gli utilzzatori l'hanno data a rullo e percio' mi mancano notizie e dati tecnici(come diametro ugello ,pressione aria )o altro per la migliore riuscita
del lavoro.
Le istruzioni del produttore non sono senz'altro migliori di quelle che mi puo' dare chi l'ha gia' data.
Se mi puoi aiutare tu che sei tra i pochi che l'hai data a spruzzo ti ringrazio di cuore

Avevo già postato le istruzioni in altro post le rimetto qui, buon lavoro:

Whilst most Coppercoat is applied by roller, it is perfectly acceptable to apply it by spray and any good boat spray specialist will be able to achieve an excellent finish.
The key is to apply it in several thin coats - this product is much heavier than conventional paint so you must take care not to apply it too thickly too quickly.
It is all too easy to apply too much too soon, which ends in runs and sags, so do take care and do not try to work too fast – do allow the appropriate partial cure time between each coat/pass.
It is worthwhile having your spray man practice with half a litre against an old board or wall and getting the technique correct, before then starting on the boat.
You will need to use a pressure pot system, with a three horsepower compressor (minimum), 15 cubic feet per minute and 120psi.
For the gun we recommend a 705 aircap, FF needle and 1.6 to 1.8 fluid tip.
Have as short a lines as possible (with few joins), so as not to lose pressure between the compressor and the gun tip.
You will need to thin the product by 20% using Iso-Propanol alcohol. You will also need this thinner to clean the lines afterwards.
Coppercoat is only spray applied by people who are used to spraying and have spray equipment, so by definition they are experienced.
Consequently they normally only need the most basic of additional info, as they set up all the equipment correctly during the practice trial. But by giving them at least the above info, they can turn up with the correct gear.
