sa-3

[Saravanan Mohan]

Gents,

 

To achieve sa-3 surface preparation grade using dry abrasive blasting method can we use sand as a abrasive?

Is any picture about this in the pictorial standard?

For SA 2.5 / SA 3, I recommend to use use grit blasting / shot blasting , if required a combination of both but not sand blasting. Nowadays, it is prohibited to use sand in blastng, as it  causes Silicosis, a lung disease, that is caused by the inhalation of toxic, carcinogenic crystalline silica dust particles. Silicosis is incurable and irreversible. 

 

Thanks
