Big Impact DIY: How To Refinish Your Porcelain Sink

How to breathe new life into an old yellowed and chipped laundry sink.

If you live in an older home, like me, the chances are that you might have an old sink or bathtub that you need to refinish.  You might try and hide this sink or tub from your friends and family because it might put you to shame.  And no matter how hard you scrub it, the yellowed surfaces won’t come clean, and you can’t magically make the chips and scratches disappear.

But there is hope!  We used to have one of these sinks in our laundry room.  And the worst is that I could not hide it.  Our kitchen/laundry room door is the main exit to our garden, so everyone who visited could see it.  I’ve had a Tub & Tile Repair kit for a couple of years, sitting and waiting for this project.  I finally got around to refinish the porcelain sink a couple of weeks ago, and I can tell you that it is not as hard as you might think.

How to Refinish your Porcelain Sink or Bathtub using Rust-Oleum’s Tub & Tile Repair

Touch up Chips and Scratches

We had some big, and a lot of little chips in the sink.  Hey – it was probably installed when the house was built in the 1970s.  I am proud to say that we have not contributed to the big chips though – maybe we caused some of the small ones.  I decided to fix them up first with Rust-Oleum’s Tub & Tile Touch-Up

The touch-up kit is easy to work with.  You don’t need full PPE for this – only latex gloves.  You just mix the two parts, and the one bottle comes with a handy application brush.  I will say that the brush is a bit wide – which makes it difficult to touch up small chips – but overall, the process was easy.  You can do multiple coats, ten minutes apart to fill up deeper chips.  I left it to dry for two days before moving onto the next step.

Be sure to follow the exact instructions on the packaging regarding the cleaning of your surfaces beforehand as well as proper application.

Clean and Prep-work

Next, it is time to prepare your entire sink or tub surface for painting.  Look at the instructions and follow them carefully.  Make sure you follow all the steps, as this will have an impact on your final product.  We did not have any peeling paint, but we did remove the existing silicone/caulk around the sink.  I used degreasers, abrasives, bleach and sanding paper as instructed. 

I could not remove our drain, so I taped it off with masking tape.  You can do this by taping off a larger section and then you can cut the tape with a craft knife in the exact round shape of the drain.  Rub over it to make sure the tape has well adhered to the surface. 

Now, you are almost ready to refinish your porcelain sink.  Gather your PPE and a tack cloth for the next step.

Paint the Sink and Let Cure

I used Rust-Oleum’s Tub & Tile Refinishing Kit, and for this part, you need proper ventilation.  I have a large window and a door right at that sink, and I still put up a fan as well.  I directed the fan towards the door to make sure the fumes are directed outside, and it worked quite well.  Even if you think you have proper ventilation in the room, consider using a fan too – the fumes are bad.  Wear goggles and latex gloves.  Wear a mask – and no, a fabric face mask you use because of COVID is not suited for this job.  Use a proper respirator mask. 

When you are ready, start mixing the two parts as indicated on the packaging.  Wipe the surface with a tack cloth just before painting.  You can either paint by brush, roller or sprayer.  I did as much as I could with a roller and used a paintbrush for the tight spaces.  You can recoat after one hour.  I found that the roller puts the paint on in thinner coats, and as a result, I had to do three coats to get proper coverage and hide the yellow forever.

Let your sink or tub dry and cure for at least three days before exposing it to moisture.  We even waited the three days before touching up our wall tiles & installing new silicone.

I definitely love the outcome – this sink now looks brand new, and I don’t have to hide in shame anymore.  I did not find the product difficult to work with – if you do a lot of painting, it is not a hard project to complete.  The only tricky part is the fumes which require you to use the proper PPE – but if you do that and ensure adequate ventilation, you are good to go.
