Stucco has been used since ancient times and is still widely used throughout the world. It is one of the most common of traditional materials, and with the popularization of Portland Cement the composition of stucco has become a harder material.
Stucco is applied directly, without lath, to masonry substrates, such as brick, stone, concrete, or hollow tile. But on wood structures, stucco, like its interior counterpart plaster, must be applied over lath in order to obtain an adequate key to hold the stucco. Like interior plaster, stucco has traditionally been applied as a multiple-layer process, sometimes consisting of two coats, but more commonly three.
Dash Stucco Finish:The Dash finish is sometimes called "Splatter Dash", "Rough Cast", or "Dash Coat". Dash texture is a grainy, somewhat pebbly finish composed of many tiny, sharply defined and closely packed peaks. Dash texture creates an attractive appearance to stucco and relieves the surface effectively.
Sand Float Stucco Finish:The Sand Float finish is a rough finish obtained by using a wood float. It has a heavy finish with a circular pattern.
Lace Stucco Finish: The Lace finish has become very common in the past twenty years. This finish however, has several drawbacks with collecting dirt, moisture and chipping. The lighter lace pattern is more popular because it hides cracks and imperfections, stays cleaner than the heavier finish, and is easy to patch for future changes. This finish is commonly used on newer homes throughout southern California.
Decorative Stucco Finish: Decorative stucco finishes are created using hybrid techniques that combine floating, dashing and troweling. Decorative finish types include scraped, simulated timber, cat face, marblecrete, trowel sweep, brick, web, frieze and region-inspired techniques such as Arizona, California, Santa Barbara, Spanish, Monterey and English.
Most stucco deterioration is the result of water infiltration into a building's structure. Potential causes of deterioration include: ground settlement, lintel and door frame settlement, inadequate and leaking gutters and downspouts, intrusive vegetation, moisture migration within walls, vapor drive problems, excessive ground water and poor drainage around the foundation. Water infiltration will cause wood lath to rot, and metal lath and nails to rust, which eventually will cause stucco to loose its bond and pull away from its substrate.
