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. Apply a coat of glue to the edges of the boards but do not assemble! Allow this first layer to soak in. Then apply a second layer of glue and assemble the panels. The first layer 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.
