MDF (medium-density fiberboard) is inexpensive, durable, and a good choice for many woodworking and carpentry projects. Learn how to use it correctly, and how to avoid common mistakes.

• Make Your Own Trim
• Combine MDF With Wood Moldings
• Prepare for a Dust Storm
• Avoid Full Sheets
  Try MDF shelving, usually in 1 x 8-ft. sections. I like to slice these long, easy-to-handle shelves into trim stock.
• Sand, Prime, Sand (Kilz, 100 grit)
• Don’t Let It Get Wet
• Reinforce MDF Shelves
• Don’t Use a Hammer (drill holes first or use a trim nailer)
