In a previous post, I discussed the usual problems with kitchen cabinet doors and that's vulnerability of the concealed hinges getting pulled out. In most cases, the problem manifests itself with the hinge screws getting loose and the kitchen cabinet door misaligning from the cabinet and sagging.

Here are the procedures to readjust the cabinet part of the concealed hinges and effectively reattach them to the cabinet. The kitchen cabinet door being described by the procedures below is the right door (door swings right)
  • With a Phillips-type screwdriver, completely remove the hinge screws in the cabinet part of the concealed hinges. Do this for both of the concealed hinges. Usually, the screws of the door part of the concealed hinge don't easily come off so there's no need to unscrew them.

    You'll notice how one of the concealed hinges has loosened. The scratched paint on the cabinet wood resulted from the constant wiggling of the metal loose hinge in its place. You'll also notice how the door sags by the misaligment of the door edge relative to the cabinet. The gap between door and cabinet appears wider at the top.

  • Prepare a dish or tray with water just enough to dip your fingers in it.

  • Mix the two parts of the wood epoxy just enough for fill in the screw holes. Alternatively, you can use a wood filler for this purpose.

    The wood epoxy I use comes in a tube as shown below. As in most epoxies which have hardener and adhesive, the tube type epoxy also has two parts. One part of the epoxy is inside (colored white) while the other part is on the outside (colored pink).

    Using this kind of epoxy is convenient. You only need to cut or slice with a putty knife the amount you need. The piece would automatically have the right amounts of hardener (part A) and adhesive (part B).

  • Dip your fingers in the water to moisten them as needed. Doing so will prevent the epoxy from sticking.

  • Force the mixed epoxy into the screw holes. You can do this by pushing epoxy in them. When the epoxy spreads out on the wood surface, scratch the material back to to where the screw hole is located and push again. See below.

  • Do this repeatedly until there is little epoxy that spreads on the surface, meaning, much of the epoxy has entered and filled the hole. You only have a few minutes before the epoxy hardens so act quickly. Be sure to read the epoxy label for curing times. There is no need to keep the epoxy material flush to the surface as this will be covered by the concealed hinge. Also, epoxy material will still come out when the screws are placed in.

    Notice the scratched paint at the edge of the kitchen cabinet door. This resulted from its constant banging on the cabinet frame because of the loose hinges.

The next post will discuss the correct placement of the concealed hinges and securing them with the new screws.
