MDF stands for "medium density fiberboard" and is an inexpensive alternative wood product that can be used for many remodelling projects. Building cabinet doors using MDF can save money yet still provide a professional look to your home project. If you have do-it-yourself skills, you should be able to handle this project.
Clear a work space in the garage or outside as the MDF panel typically comes in 4-by-8-foot sheets.
Set up the sawhorses, adequately spaced so the MDF panel can lay flat.
Measure and mark the size of the cabinet door on the MDF panel. Use the straight edge to draw a line from mark to mark.
Cut out your panel, using the circular saw.
Smooth the edges of the cabinet door, using sandpaper.
Prime and paint the cabinet door. Paint the interior and exterior of the door and let dry.
Install the hinges and knob on the cabinet door.
Secure the finished cabinet door to the cabinet base. Finish with a damp cloth to remove any dust residue.
Wear protective eyewear and a dust mask as the MDF is very dusty. Always pre-drill holes before installing any screws.
If using a full sheet of MDF, you may need an additional person to help, as the panel is heavy. MDF is prone to warping in high-humidity areas such as a kitchen or bathroom and should be painted for protection.
