Surface preparation method
(OP)
Hi guys,
Are sand blasting & shot blasting processes same?
These are related to surface preparation before painting.
If they are not same, which one is better and why?
Thanks

RE: Surface preparation method
Sand blasting in many cases is used to remove previous coatings, rust, scale, etc., down to bare steel. Also changes surface texture.
Shot blasting will do this also, but has added property of cold-working the surface of the steel & makes the surface harder.

RE: Surface preparation method
I think the best terms to use for describing a process to clean a surface are either "media blast" or "grit blast", since there are numerous types of abrasive media used such as sand, glass beads, baking soda, walnut shells, ceramic particles, metal slag, or even frozen CO2 powder.

RE: Surface preparation method
It's a new information for me.
RE: Surface preparation method
sand blasting, IMHO, wouldn't create this, and is more a surface preparation for painting.

RE: Surface preparation method
steel shot blasting is a process commonly used to clean metal parts with no intention of altering the mechanical properties in the surface of the component. A good example is the cleaning of sand castings using Wheelabrator machines. The shot blast removes flash and contaminants like mold sand from the casting surface, and produces a uniform surface texture, but it is not intended to alter the mechanical properties of the casting.
