Exposed aggregate, micro exposed, acid-etched, sandblast finish... - how do they differ?
While exposed aggregate and sandblasting offer a certain texture depth, exposed aggregate (by choosing from a wide range of different exposure depth types and sandblast by selecting and configurating the sand and the sandblasting device), by comparison, acid-etched surfaces have an even finer exposure depth, where the concrete surface resulting in a “silky” optical finish, often with a “deeper tone” due to the effect of the acid.
