Fasteners

Glue

• Wood glue - essentially the same as Elmer's white glue but with coloring and additives to make it set up faster than white glue
  

• White glue - the regular stuff commonly found at your local "-mart" store.
  

• Polyurethane glue - unlike yellow or white glue that requires air to cure, polyurethane glue requires moisture to cure. Polyurethane is excellent at joining dissimilar materials such as wood and plastic. When curing, it "foams", so clamps are a must with this type of glue.
  
  

• When working with MDF, remember this trick to get better results. You'll find the edges rougher and more porous than the face. Gluing as you normally would can "starve" the joint of glue. To avoid this, "double glue" the joint. The first layer soaks in and helps seal the surface, while the second application works to create a solid bond.
  

Nails

Self-explanatory, except to say for building a cabinet, screws are the preferred method, but nails can be used if you wish, however, plywood or solid wood panels are recommended if using nails

Screws

Screws will require special methods when used with MDF. Screws installed into the edges of MDF can cause it to split, resulting in a weak or failed joint. You'll need to drill a pilot hole for your screws. Use a drill bit the same diameter as the shank of your screw, and drill your hole slightly deeper than the length of your screw. Secondly, use sraight-shanked screws to avoid splitting the material and also to get a better grip in the material. Special screws, called Confirmat screws, are available but somewhat costly.
