Sculptured concrete is now a normal feature of almost all facade construction in Western Germany. In recent years it has grown in popularity in most countries of the world because of the demand for pleasing appearance as well as structural function in concrete and the availability of inexpensive, elastic form liners that can reproduce very fine details. Perfect uniformity of appearance over a large concrete surface seems almost impossible to achieve. The surface is usually blotchy, showing uneven formwork joints, form-oil stains, batch flow lines or other defects. The new elastomeric form liners overcome these problems by creating a surface that is uneven to start with; the recesses create shadow in which nail heads, lap joints and tie marks can be hidden from view. The variety of sculptured effects that can be created in this way is almost infinite: very fine wood graining, rough skin textures, chiseled concrete, deep-etch grooving, geometric and abstract patterns and fantasies, personalized finishes, and artistically created reliefs. Also, because of the flexibility of the liners, curved surfaces can be formed without difficulty. Liners are usually supplied in sizes sufficiently large for standard construction heights. If horizontal construction joints cannot be avoided, it is often advisable to accentuate the joints with filler strips recessed in the concrete. Elastomeric liners can be bonded to any formwork surface and stripped off again as desired. After attachment the liner surface is brushed thinly but evenly with a release agent. Excess agent must be wiped off. The agent is a special composition that does not affect the elastomer.
