Today, you are going to learn how to paint a porcelain kitchen sink (or any other sink that you have at home), and how to get paint out of a porcelain sink.

That is a reasonable nuance since, if your sink has already been painted before, you might want to remove the old paint before applying the new one.

Also, we will explain how to apply a design on your sink in case you want to get totally creative, and whether or not it is possible to spray paint this item.

How to Paint a Porcelain Sink?

You may want to paint or repaint your porcelain sink for many reasons. maybe, you are just tired of it being all white and boring, or perhaps, its initial color does not fit the new color of your walls and so you want to repaint it to make it look more fitting.

Or perhaps, you are going to sell your house or apartment, and you want the sink to look better, but you would not like to replace it since it is still in a good state (well, except for the color, perhaps).

No matter why you decide to do it, painting a sink is always cheaper and faster than replacing it, of course, except for the cases when it’s broken and you must replace the sink.

And if this is already decided, and you have already bought the paint and the brushes, we guess it is time to explain how the painting process will go. But first, let us familiarize you with the general sequence of actions that will have to be taken:

  1. Get your room ready for the upcoming painting process
  2. Clean the sink
  3. Apply the bonding agent
  4. Protect the fixtures and accessories
  5. Apply the paint
  6. Cure the paint

Done! Looks pretty simple, huh? But we want you to keep in mind that, if you want to get the best results, you should choose a paint color that closely matches the original color of the sink.

In case you need to change an outdated color, you need to reapply thin coats of enamel until the surface of the sink is completely covered.

But anyway, always keep a small amount of paint on hand in case the overcoat chips, since you don’t need the original paint to show up from beneath.

Also, we suggest you make sure that you have prepared all the tools that you will need for the upcoming painting project.

Get Your Room Ready

No matter whether you will be painting a sink in your bathroom or a kitchen, you need to protect the walls and all the objects around to avoid them being accidentally painted as well!

That’s especially crucial if you are painting in the bathroom since these rooms are usually rather small and every careless move of the paint brush can leave very artistic but vey unwelcomed splatters of paint on the walls.

So grab some plastic sheeting and cover the walls and the floor around the sink.

If you are painting in the kitchen, make sure you also cover the cabinets or shelves above the sink.

Clean the Sink

Before you start painting, your sink must be cleaned.

If you apply the paint onto the dirty surface, it will not adhere properly resulting in the uneven and messy coating that will soon start peeling off.

We suggest you clean the surface and the bowl of your porcelain sink with the help of any household cleaner that you usually use at home.

Make sure those products are able to cope with soap scum, as well as rust and lime.

However, you should always keep in mind that any harsh abrasives are not allowed on porcelain!

Such products can leave rather noticeable scratches on the surface of your sink, especially if the porcelain is pretty old.

When you are done with cleaning, you can make use of denatured alcohol as a past-cleaning solution. It will help to get rid of the cleaning products leftovers.

Simply dampen a clean cloth with denatured alcohol and wipe the entire surface of your sink. This product will easily remove any residue that might be left after the use of cleaners.

Now just let your sink dry completely, and you can move to the next stage.

Applying the Bonding Agent

Now you need to cover the entire surface of your sink with a special bonding agent.

This product can be bought in any hardware store, but make sure that you buy the one that is designed for porcelain exactly!

Put on protective gloves and cover your sink with the product with the help of a rag to wipe the bonding agent on the sink’s surface.

It will help the paint to adhere way better and smoother. One coat of bonding agent is more than enough to prepare the sink for the upcoming painting application.

Make Sure Your Fixtures And Accessories Are Protected

You should mask off light fixtures, mirrors, any accessories, plumbing and hardware with painter’s tape and plastic sheeting.

Use a spray gun with a compressor to apply a coat of acrylic urethane enamel to the sink.

While doing this, remember to wear a mask with a ventilator to avoid inhaling the chemicals, and also, keep your bathroom windows and other windows open throughout the house to ventilate the space.

Apply the Paint

Now you can apply the paint evenly across the entire surface of your porcelain sink. If you are using spray paint, let it dry for fifteen minutes, and then apply two more light coats of paint remembering to let it dry between the sessions.

Also, if the weather allows and if your sink can easily be removed, we would recommend you take it outdoors to complete the painting procedure.

Like this, the sink will not just dry faster and better, you will also avoid filling your entire home with the odor of paint which can be toxic for people and cause headaches if inhaled for long enough.

Remember to Cure the Paint

Finally, the very last step in your painting project is curing!

To do it, you need to place a heat lamp next to your freshly painted sink for about one hour to let the paint cure. In case you have no heat lamp, no worries! Simply let the enamel dry completely itself.

And once your sink is totally dry, oit is recommended to wet sand it with the help of 1000-grit sandpaper.

Like this, you will easily level out any uneven patches and rough areas on the surface of the sink that might be left after the painting process.

Add the final stroke by wiping the entire sink with paper towels to remove dust after sanding.

Then, using a power buffer, foam pad and auto compound, remove any remaining scratches. Hand buff with car wax to create a shiny luster.

Well, this is basically all that you will have to do to get your porcelain sink painted!

Test Your Paint

If you are removing an old paint that was not applied by you (for example, if the sink was painted by the previous homeowner), you need to test the paint first to know what solvents to use.

It must be done before you start the process since you need to know for sure whether this paint is oil-based or water-based.

The check is pretty simple: you just need to moisten a rag or a cotton swab in denatured alcohol or rubbing alcohol and rub the painted surface for a few seconds vigorously.

Now look at your rag/swab.

Do you see the traces of paint on it?

If you do, then the paint is water-based. If you don’t, then your paint is oil-based respectively.

Depending on what type of paint you are dealing with, you will want to use different products.

If your paint is water-based, you can keep on rubbing it off with alcohol and then just wash the surface with an abrasive sponge and soapy water.

In case you are dealing with the oil-based paint, opt for either a lacquer thinner or acetone.

As an option, you can use a paint stripper: it’s even better since this product won’t damage the porcelain and it works on both water-based and oil-based paints!

All you need to do is to apply it with a brush over the sink, wait for ten or fifteen minutes until the paint starts blistering, and then remove it with a paint scraper.
