Methods and devices for modifying a building panel are disclosed. A solution is applied to a surface of the building panel. The solution consists of light alcohols. A force is applied to a portion of the building panel substantially normal to a horizontal plane of the panel. The force causes a deformation of the portion of the building panel.

A water-based coating composition is described herein. The composition includes an aqueous dispersion derived from an ethylenically unsaturated monomer and one or more organic solvents. The composition when applied to a substrate and allowed to dry provides a wet look to the substrate.
