Q. What glue works best with MDF?

A.Just about anything, including PVAs, epoxy, and polyurethanes. However, because MDF tends to suck up aqueous glues, when edge-gluing solid wood to the edges of MDF, it’s advisable to pretreat the MDF with Wood Size (available from Franklin) or Glue Size (available from Custom-Pak Adhesives) to minimize suck-up of the glue and a resulting poor bond.
