What specific paint property must be adjusted to achieve the desired faux finish decorative technique?

• A. The pigment color.
• B. Paint viscosity must be adjusted to control the flow and texture.
• C. The drying speed
• D. The type of solvent

Answer: (B)

The key idea is that faux finishes rely on how smoothly the paint can move and hold the texture you create with your tool. Adjusting viscosity—the thickness of the paint—directly controls flow and texture. Thinner paint flows more readily, blending colors and creating subtle, seamless patterns; thicker paint holds brush marks, spatter, or drag lines for more defined textures. This control over flow is what lets you achieve marbling, wood grain, ragging, and other decorative effects. While pigment color changes the look, and drying speed or solvent type can influence working time, the actual technique depends on how the paint moves, which comes from its viscosity.
