Which finish is often used for providing extra texture to stucco?

Choosing sand as the finish for providing extra texture to stucco is grounded in the traditional practices of stucco application. Sand is integral to the stucco mix itself, enhancing the depth and tactile quality of the surface once applied. When incorporated into the final layers or used as a finish coat, sand helps achieve a variety of textural effects, from a rough, hand-trowled appearance to stippled looks that can enhance the visual interest of a home or building exterior.

Furthermore, different types of sand can be used to create varied finishes, allowing for customization in texture. This adaptability makes sand a favored choice among professionals seeking to enhance the aesthetic and functional qualities of their stucco work.

Other choices such as paint, trowel, and sealant do not serve the same purpose when it comes to adding texture. Paint will primarily alter the color without significantly affecting the surface's tactile feel, trowel relates more to the application technique than a textural enhancement, and sealants are used primarily for protection and waterproofing, rather than texture. Hence, sand is the ideal answer for adding extra texture to stucco finishes.
