How to Add an Undercoat to a Stainless Steel Sink

Remove the Sink

• 1

  Turn off the water at the main valve in your home. Shut off the electrical circuit that powers the garbage disposal. Turn the shut-off valve located beneath the sink to the right to close it.

• 2

  Place a bucket beneath the sink to catch water left in the P-trap. Remove the nuts that connect the water lines to the sink with an adjustable wrench.

• 3

  Unscrew the nut that holds the hose for the garbage disposal in place. Unhook the hose and electrical wiring attached to the disposal. Insert the screwdriver to loosen the retaining ring on the disposal. Remove the disposal.

• 4

  Loosen the metal clips that hold the stainless steel sink to the countertop. Lift the sink from its place in the countertop.

Add the Undercoat

• 5

  Don your protective rubber gloves, face mask and eyewear.

• 6

  Place plastic sheeting on the ground in a well-ventilated work area.

• 7

  Turn the stainless steel sink upside down on the plastic sheeting. Clean the underside of the sink with soap and water. Dry the sink with towels.

• 8

  Hold the can 12 to 24 inches away from the surface and spray a thin layer of the undercoat using short, quick strokes. Let the undercoat dry for four to six hours.

• 9

  Turn the can upside down and hold the spray valve down for one short spray to clear the nozzle.

• 10

  Apply a second thin coating of undercoat to the sink. Let the undercoat dry overnight.
