There really is no limit to the finishes you can achieve with a decorative overlay, ranging from ultra-smooth to heavily textured. It all depends on the type of overlay system and the tools used to apply it.
- Spray-applied toppings are probably the most popular finish for knock-down texture
- Microtoppings and skim coats allow you to achieve a wide variety of decorative finishes by using tools such as hand trowels, floats, rollers, and rubber squeegees
