What is the technique to be used in surface cleaning?
Dry cleaning methods mainly include laser cleaning, plasma cleaning, dry ice blast cleaning, high-speed impact jet cleaning and super-condensed supercooled kinetic cleaning. In contrast, wet cleaning methods use water or other liquid solvents as a medium to remove impurities by soaking, spraying or vibrating.
What does surface prep mean?
Surface preparation refers to the various methods that can be used to treat the surface of a material prior to coating application, the use of adhesives and other procedures. Surface preparation is essential for treating steel and other substrates before they are painted, coated or lined.

What is SSPC sp8?
SSPC-SP 8 is a surface preparation standard intended for acid pickling to be performed immediately prior to painting. As such, the standard includes elevated surface requirements that make sense if acid pickling is used as the primary method for cleaning and etching the steel surface prior to a coating application.
What is the difference between sweep blasting and sandblasting?
Sweep blasting is preferred over standard blasting because standard blasting could remove most of the coating, whereas sweep blasting, when done correctly, removes only zinc corrosion compounds and not the zinc metal layer (eta layer).
