Epoxy on Your Sinks

This pandemic is bringing out the creativity in people. Homeowners are DIY-ing almost everything in their household—upgrading spaces from bedrooms to living rooms to bathrooms.

While everyone is excited, knowing what to use and what not to use on certain things is essential to avoid regrets.

Can you use appliance epoxy on sinks? Although appliance epoxy is commonly used for appliances, this too can be used for sinks. This will not be a permanent fix, but it can still be good for freshening up your sink color.

Nobody wants a discolored fixture. Read this article to learn more about appliance epoxy and how you can safely paint it on your sink.

What Is Appliance Epoxy?

Appliance epoxy is a strong, moisture-resistant enamel designed for indoor metal surfaces.

It offers a flat, washable surface for the external finishing of appliances such as dishwashers, washing machines, dryers, and other indoor metal applications.

It is ideal for appliances or bathtubs and sinks with rusted, scratched, or worn surfaces.

You might have difficulty buying an appliance epoxy that suits any of the newer finishes, like black stainless steel or champagne.

Use appliance epoxy when the temperature is about 50 to 90°F, and the humidity is below 85% to ensure adequate drying.

Blend carefully to ensure that all dye has been redispersed. If required, thin the substance with mineral spirits or acetone.

Use a high-quality brush for small areas and add soft, even coats to ensure even flow and finish. Use a high-quality foam roller for broad surfaces to provide a smooth finish.

Painting Sink with Appliance Epoxy


Here are the things you will need to paint a sink using appliance epoxy:

  • Sandpaper
  • Appliance epoxy paint
  • Painter’s tape
  • A good quality paintbrush or roller
  • Cloths or newspapers to protect your cabinets and floor
  • Vapor mask

A Little Advice

Before anything else, here are the things you should note when painting a sink using appliance epoxy:

  • Buy the Right Paint – Rust-Oleum appears to have the most choices regarding the forms and finishes of appliance epoxy. Options include a 30-ounce epoxy paint can in white or stainless steel. It also has an epoxy spray can in black or white and a slim 0.6-ounce container in white or black for touch-ups.

  • Make Sure You Have Enough Paint – Of course, you do not want to run out of paint in the middle of your task. User reviews say that better it’s better to purchase the 30-ounce paint.

  • Prep Your Workspace – When painting your sink, be sure that nothing is on it. Tape any display pieces with painter’s tape.

  • Sand Down the Existing Paint – You can achieve the best results by using the paint that comes in the 30-ounce can. It could also make more sense to paint the whole appliance entirely, rather than just one part. This will create a more consistent finish.

  • Applying the Paint – The epoxy appliance instructions mention that you should start adding coats one hour after the first coat. But it would be better if you waited until the next day to apply another coat. A single coat typically takes 24 hours to fully dry.

Start Painting

Preparing the Workspace

  1. Remove all knick-knacks, towels, etc. Place two sheets of tape on the drain plug.

  2. Sand the rust spots, if any, with wet and fine metal oxide sandpaper. Remove the brown, rusty, wet residue from the paper towels.

  3. Dissolve and use the cleaning powder that comes with the package to disinfect the whole sink thoroughly according to the instructions.

  4. Use the steel wool enclosed in the package to roughen up the entire area. Follow the instructions for this process.

  5. Taping and hanging plastic are essential to this task. Tape over the entire faucet fixture and hang plastic over the mirror. If you don’t want to drop any paint on the tile around the sink, tape it.

  6. Turn off the feed valve under the sink so that no one unintentionally turns it on. This epoxy appliance leaves a perfect drop that sticks on everything that covers the floor and other fixtures.

  7. Apply a rust converter substance, by either brushing or spraying. Let it dry overnight until the epoxy sink is sprayed. It is a smart idea to stick two crossed pieces of tape over the sink so that no one touches the wet paint.

Painting the Sink

  1. Wear a face mask, as this material is obnoxiously smelly! Don’t just open a window; run a fan in the bathroom if you have one.

  2. It is recommended that you wait two to four hours between coats. However, follow the directions to make sure. If you paint the sink too much in one spot, it will drip. The drips are hard to get rid of once they are there.

  3. Do not take off the tape until the sink is dry. Again, follow the instructions, though you should probably wait two or three days before using the sink.

Three coats are fine, but do a final fourth coating if you want that added shine after 24 hours.

This will give you more assurance that the paint is durable and ready to use for anyone in the household.

Painting Bathtub with Appliance Epoxy

Aside from painting appliances and your sink, you can use appliance epoxy for your bathtub.

  1. Clean the tub well with soap and water and make any necessary repairs before starting.

  2. Mask off the wall at the side of the tub with masking tape. Do not forget all other areas not to be sprayed, such as the drain.

  3. You can paint with a small paintbrush for masked edges. You can use either a large brush or a roller for larger surfaces.

  4. Two coats are almost certainly necessary and the drying period can vary based on the color you use.

  5. After a second drying period, remove the masking tape and re-install any missing products, such as faucets.


Appliance epoxy paint is not only for appliances. You can use it for other things, such as your sink, bathtub, and cabinets.

Appliance epoxy is perfect if you are trying to save money.

However, it is better to stick with paint designed for these things or use the spray for a smoother finish.
