RE: [MW:8882] Blasting Profile - SA 2.5

A dust contamination test is required when the time interval between a blast cleaning and paint application is too long and sometimes is more than 3 hours dependant on paint specification requirements. This means that if you apply a paint coat straight after blast cleaning then it is not reuqired to perform a contamination test. This is explained with the fact that the possibility of the contamination of the surface is very low if you apply paint coat straight after blast cleaning.
 
However, your paint specification should be a main reference point and should describe all these requeirments.

Dear All,

 

If the blasting profile is to be SA 2 1/2, whether dust contamination test is mandatory on the blasted surface.

 

Thanks and Regards

K. Vivek
