1. A method of preparing an extruded polymer-based construction material for future surface painting, the method comprising:
in response to a treatment of a surface of the extruded polymer-based construction material, increasing a surface energy of the surface from a first surface energy to a second surface energy of at least 40 dynes/cm2, the polymer-based construction material comprising a polymeric composition including a polymeric resin and a filler;
wherein the surface energy of the surface persists within 20% of the second surface energy for at least one month from the treatment of the surface.
