Use a screwdriver to take the doors and hardware off the cabinet body.
Go over the whole surface of the cabinet with a vibrating pad sander to dull it. Use dry rags to wipe off the dust.
Measure the dimensions of the first area of the cabinet to be relaminated. Mark out the measurements on a sheet of laminate veneer, using a square and pencil. Add an extra inch all around the edges.
Cut along the marked lines with the utility knife, so you have a cut out piece that's wider around by an inch than the area being relaminated.
Peel off the paper backing from the cut piece of laminate. Press the piece to the cabinet, letting it overhang the area by an inch all around.
Wrap a dry rag about your block of wood and press it over the laminate, starting at one end and working to the other, to firmly affix the laminate and squeeze out any air
Cut the extra veneer off the edges of the area and along the corners.
Repeat for each area of the cabinet. Reassemble the cabinet.
