Classification

As stucco is a term that defines a category of materials and not a material itself, it is difficult to classify them. In general terms it can be classified into:

• Traditional classical stuccos: those made with the techniques and materials that were used until the 19th century, such as plaster, marble and slaked lime stuccos.
• Synthetic stuccos: they are products obtained by mixing different materials and chemical formulations that are sold already manufactured and their composition is based on a patented mixture. They have been very popular in the United States since the 1950s.
• Modern stuccos: as plastic stucco contains synthetic resins, generally acrylic, they serve as a final coating, replacing paint, they are easier to apply than the traditional ones, they come ready to apply.

Other classification

• Scraped Stucco: Finish given to stucco by passing a toothed tool over the surface of the stucco before it sets.
• Pebble stucco: Exterior finish of a wall made by inlaying pebbles or pressing them against the surface of the stucco.
• Sprayed and ironed stucco: Finish given to sprayed stucco by troweling the protruding areas before it sets.
• Lime and portland cement stucco: Stucco made with portland cement and a portion greater than 50% of its volume, which allows an improvement in its plasticity.
• Portland cement stucco: Stucco made with portland cementand a portion of lime less than 50% of its volume.
• Chopped and ironed stucco: Exterior finish of a stuccoed wall achieved by troweling before it sets.
• Sprayed stucco: Process by which a finish is provided by throwing mortar against a wall or by means of a special machine or pneumatic gun.
• Marble dust stucco: Form of stucco in which marble dust and lime mortar are used. Also called marmoration.
