Which method can be used to achieve a textured wall finish?

The option that involves employing sponges or special brushes is correct because these tools can create various textures on a wall surface by manipulating the paint as it is applied. Sponging, for instance, involves using a damp sponge to dab paint onto the surface, resulting in a soft, textured effect. Similarly, special brushes, often designed with unique bristles or shapes, can produce patterns and textures that contribute to a more dynamic wall finish.

This technique allows for a range of artistic expressions and can enhance the overall aesthetic appeal of a space. Textured finishes can also help in hiding imperfections on the wall surface, making them a practical choice as well as a stylistic one. While other methods can create different effects, they do not focus specifically on the texture achieved through the application technique described.
