Hi,

Please help me!
I have to obtain on Aluminium coating on a 10 m long and 3 m diameter tank (carbon steel),
The thickness of the coating must be >0,12 mm.
Is it allowed to blast with quartz sand bebore spraying ?
Till now I never sprayed so big areas.
Do you know which could be the price for such a tank?
Thank you !

Hi exnnerspray

I would only recommend using alumina or chilled iron grit for final blasting before spraying. By all means use the cheaper blasting abrasives for initial cleaning of the surface before final grit blasting. The key to a good coating is in the substrate preparation, so take care when considering cheaper blasting materials.

Hi exnnerspray,
While carrying out Aluminium spray coating inside the vessle be sure about Fume and aluminium dust removal as some times aluminium dust becomes self explosive.
Wish you a best opf luck
