Clean the surface of the sink
Scrub the surface of the sink with a non-abrasive kitchen cleanser in order to remove all the grease, mold, dirt, hard water deposits, soap film and the oils. If you find any mildew on the surface of the sink, then top the non-abrasive with some bleach solution and rub for few more minutes. Rinse the sink with water until no more soapy.
Do away with the caulks all around the fixtures of the sink, using a scraper.
Repair chipped areas
Use a filler compound to overhaul all the possible dents and chips
Clean the area surrounding the sink
Accurately clean the external area of the sink using the remaining non-abrasive cleanser. Also clean the floors and walls around the specific sink.
Smooth the surface
Smooth the internal and external surfaces of the sink by scrubbing them with dry sandpaper and then rinse it thoroughly with water.
Apply epoxy coating
Now apply a thin coat of the epoxy coating, using a brush or roller strokes. Leave it for about one hour or until the epoxy dries off fully and then apply the second coat. Leave it for another one hour, allowing it to dry.
Note: You can apply the third coat if you feel necessary.
Apply a thin layer of acrylic topcoat
Grab a clean brush and top the epoxy coating with a thin layer of acrylic topcoat. It helps in adding final shine to the sink.
Once the acrylic topcoat dries thoroughly, reapply the caulk to the fixtures of the sink.
Allow the topcoats to dry and set
Leave the sink for at least one week in order to allow the layers of topcoats set and dry completely.
Wipe the floor around the sink with a wet cloth or sandpaper. Now wash the equipment used in the projects.
