MDF means medium-density fiberboard, and has become one of the most popular composite materials in recent years. Because MDF is uniform, dense, smooth and free of knots and grain patterns, it makes an excellent substitute for solid wood in many applications. MDF is made up of wood particles and resin; the particles are separated uniformly to make a fine, consistent material that is then cooked and pressure steamed. The material is then bound with an adhesive and heat pressed to produce a solid board with many of the same qualities, but without the various limitations, of natural wood. It is an exceptional base for solid color and wood grain RTF veneers and laminates, and is the ideal substrate for painting because of its smooth finish. Because of MDF’s consistentmakeup, machining this material with the right tools results in clean, sharp edges without chip-out or fuzzing. Because MDF is denser than most woods, manufacturers use only the highest quality tools of carbide and diamond for cutting. As opposed to those made of natural wood, kitchen doors made of MDF have no joints to crack after they have been painted. In addition, MDF doors come out as one solid piece, whereas traditional wood doors are 5 pieces that tend to warp over time, making them substandard for painting. MDF doors are usually used for painted light-coloured kitchens. They are highly durable and provide a clean look with a smooth finish.
