The most commonly specified textures for precast include smooth, retarded and water-washed, form-lined, sand- or abrasive-blast, acid-etched or acid-washed, and tooled
Smooth texture, as the term implies, is an as-cast finish. This texture is a direct result of the quality of the formwork surface. It is the least aesthetically pleasing but the most economical of the surface textures, especially if the surface is to be field painted. Form defects and color non-uniformities are noticeable with this finish texture, air voids are normal, and surface crazing should be expected.
A word of warning, those of you that either design for exposed concrete or who have to build exposed concrete, what you are asking for and what you are going to receive may be two entirely different things. You have to understand the distinction between the two.
Whenever somebody tells you that something is "Almost" like something else, you should usually run, don't walk. If exposed concrete is "Almost" like architectural concrete, that's a problem. Run away from those things, don't walk. If you want architectural concrete, specify architectural concrete."
