  • Steel wool
  • Trisodium phosphate cleanser
  • Masking paper
  • Soft clean cloths
  • 180-grit sandpaper
  • Acrylic spray primer
  • Epoxy spray paint
  • Metal-etching spray primer
  • Professional painter’s tape

How to Resurface a Kitchen Sink – Step by Step Guide

How to Resurface a Kitchen Sink

Step 1: Cleaning the sink

The first thing you need to do is clean the sink thoroughly, or the primer won’t stick. Apply trisodium phosphate to a clean, soft cloth and wipe all the dirt from the sink for the best results.

Trisodium phosphate is a TSP substitute, which is environmentally friendly. It is well known for its effectiveness in cleaning old soap, residue, and accumulated dirt from any kitchen sink’s surface excellently and with ease.

Ensure that you get a heavy-duty trisodium phosphate soap and rinse your kitchen sink thoroughly. Then, please leave it to dry for at least 2 hours.

Step 2: Sand the surface

Using the 180-grit sandpaper, sand your kitchen sink’s surface thoroughly, including the edges. This will make the surface rough, enabling the paint to adhere better.

Sanding will also smoothen minor scratches and chips hence very important. And since nonmetal sinks are usually stubborn when it comes to making the adhesion stick, making them coarse by sanding is the best way to go.

Step 3: Smoothen the surface

To smoothen the sink surface, you need to cover the countertops and faucets with masking tape. Secure it with tape and then apply it to your sink’s metal drain.

Then, get fine-grit sandpaper and smoothen your kitchen sink’s surface after sanding. Remove all the debris and dust using a damp cloth as well.

Step 4: Apply Bonding Agent

After making the surface smooth and removing all the dirt, it’s time to apply the bonding agent. To get an even surface, apply a thin coating and allow it to dry for 5 to 10 minutes.

Step 5: Apply Epoxy Primer

After the drying of the bonding agent on your sink’s surface, get the epoxy primer and brush it on the surface as well. Ensure that the coating isn’t too heavy.

And to prevent visible brush strokes, move the paintbrush in the same direction. Leave it for about 15 minutes to dry.

Step 6: Sand the sink surface again

Take the sandpaper and sand your sink’s surface again after the drying up of the epoxy primer. When this is done, wipe away all the accumulated dust with a damp cloth.

Ensure that the surface is sparkling clean, and apply the epoxy primer for the second time. Then, leave it to dry for 15 minutes.

Step 7: Apply an Acrylic Topcoating

Now that the second layer of epoxy primer has dried up get a high-quality brush and apply a light acrylic coating. Use the same direction while brushing for uniformity and avoid nasty brush marks on your sink’s surface.

Apply the second acrylic coating after the first one dries up.

One thing to note is that this primer (acrylic) works best on nonmetal sinks. If you have a metal kitchen sink, use a metal etching spray primer.

If using the metal etching primer, repeat the same procedure, ensuring that you apply thin layers and allow enough time for sufficient drying.

And after the last coating, leave your kitchen sink to dry for 24 hours before cleaning it. To get the best results, refrain from using it heavily for about 5 days.
