CDF uses only hardwoods such as mahogany, red oak, maple and poplar in the construction of our frames. Once constructed, frames are either stained, painted or left natural and then sealed with our clear top coating and then cured. This process creates a surface that resists both scratches and graffiti. Infection control concerns are also minimized due to the density of our sealant. Proper disinfecting is achieved with the use of a disinfecting wipe or solution. Even permanent magic marker can be removed without damaging the surface of the frame.
