A wide variety of finishes are available in architectural precast concrete, ranging from a smooth form or as-cast finish to deeply exposed aggregates. As a rule, a textured surface provides more uniformity than a smooth surface because the natural variations in the aggregates will camouflage subtle differences in the texture and color of the concrete. A medium sandblast finish, for example, generally provides more uniformity and consistency than an acid wash finish. Dividing larger areas into smaller ones with reveals or rustications can also help lessen any variation in texture that might be visible.
