• Building ideas for MDF molding can be essential to maximizing creative designs, according to Master Renovator. MDF molding is a fiberboard composite and a cost-savings option when compared to wood. In fact, nine out of 10 homes built today include MDF molding. While MDF options save money they are not as durable or reliable as solid wood. Speak with a contractor before making a final choice.
  
  

Build in Dry Places

• MDF molding is easy to paint and attach to almost any wall, according Master Renovator. But you should only build using MDF molding in dry places. MDF rapidly absorbs water and causes the material to expand and deteriorate.
  
  

Use Molding Blocks

• MDF is flat and will provide an even look on the base of almost any wall which is beveled or misaligned, according to Master Renovator. However, MDF will easily bend or break if it gets hit by hard objects or catches on hooks, shoes or doors. Using molding blocks in addition to MDF itself can help prevent it from accidentally snapping. Molding blocks are attachable pieces which fit onto the ends or corners of MDF.
  
  

Use Specific Tools

• MDF fiberboard is composed of sawdust and finished materials are extraordinarily dense, according to Master Renovator. The density of MDF makes it difficult to nail. In fact, hammering nails into MDF can cause it to break. Use air nail guns or wall glue to attach MDF. Air nail guns inject various sized nails without the repetitive, pounding force of a hammer. Permanent glue does not require nails or hammering at all.
