    Abstract: The present disclosure relates generally to a surface structure for construction products, for example, suitable for construction products that cover visible interior surfaces, such as drywall and ceiling panels. The present disclosure relates more particularly to an interior surface construction product including a visible surface covered with a texture including surface features having a height in a range from 20 μm to 2500 μm. The visible surface has an average rotational derivative that is no greater than 1.2*a respective rotational derivative of a Lambertian surface under the same lighting and viewing conditions. The rotational derivative is the percentage change in radiance from the visible surface in a viewing direction when illuminated in an illumination direction as the surface rotates about an axis that is perpendicular to a plane defined by the viewing direction and the illumination direction.
