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.

Defect-hiding surface textures

The present disclosure relates generally to wallboards, for example, suitable for use in constructing internal walls. The present disclosure relates more particularly to a wallboard and a method that provides simplified high-quality surface finishing. The wallboard includes a wall panel having a front surface and a rear surface. A sandable coating is disposed on the front surface of the wall panel. The method includes positioning wallboards adjacent to one another, applying sandable joint compound over joint formed between the wallboards, and sanding the joint compound and the sandable coating of the wallboards.

Wallboards, wallboard systems and methods for installing them

The present disclosure relates generally to building surface products, for example, panels suitable for forming a building surface. The present disclosure relates more particularly to a building surface product including a gypsum panel with an upper edge that overlaps a lower edge of a neighboring gypsum panel.
