Updating old cabinets
Remove the cabinet doors and drawers and remove all pulls, knobs, latches and other hardware from these parts.
Place the hardware and screws in plastic bags inside the cabinets where they will be easy to locate when you're ready to reassemble.
When sanding, there is no need to remove all of the old paint if it is sound and well-adhered; just roughen the surface to provide the new paint with a firm, clean base for better adhesion.Number each door and its corresponding location as you remove them.Do not mix them up or the hinges may not line up properly when you reinstall them.Allow the filled areas to dry, then use sandpaper to smooth out the surface of the cabinets.
If your repainting project is just a facelift for the cabinets, you don’t need to sand and paint the inside of the cabinets; mask off the interiors with painters’ tape for a clean finish and sand only the front surfaces and visible edges of the cabinet face frames.
If you have a pneumatic air compressor, use high-pressure air to blow the dust out of crevices or molding details.
