Soda or crushed glass? Selecting blast media by surface
SBS soda breaks up on impact and is useful for selective removal of coatings.
SodaBlast Systems · SBS SYSTEM
In short
SBS soda breaks up on impact and is useful for selective removal of coatings. Crushed glass has angular grains and can create a surface profile. Start with the next operation. A timber surface left on display and a steel frame sent to the paint shop call for different test pieces.
Five grades of crushed glass
The SBS glass brochure lists five size bands in millimetres: 0.15–0.3, 0.2–0.5, 0.3–0.8, 0.5–1.0 and 1.0–2.0. For example, the finest grade is listed for selected timber and aluminium work, while the two coarsest grades include steel roughening. Use the sample to agree texture and consumption before ordering the batch.
On wet steel work, agree how the part will move from stripping to the painter. Discuss an appropriate inhibitor and compatibility with the next coating. On timber, inspect the dry sample in side light before settling the grade for the whole job.
