What is a common benefit of using smooth finishes on drywall?

Using smooth finishes on drywall provides an ideal surface for painting because they create a uniform and blemish-free foundation that enhances the final appearance of the paint. A smooth surface allows paint to apply evenly, reducing the likelihood of issues such as roller marks or uneven texture that could occur with more textured surfaces. This finish also helps to ensure good color representation and avoids the need for multiple coats, as any imperfections in the drywall are less likely to show through a well-applied coat of paint.

In contrast, while a smooth finish can also aid in wallpaper application, the level of adhesion is influenced by other factors such as the wallpaper type and adhesive. Although smooth finishes can help minimize repair needs, the primary focus is not on that aspect. The easy application of textures is not a characteristic associated with smooth finishes, as texturing typically requires a rougher or more textured surface to effectively adhere and show the desired pattern.
