How to repair porcelain sink?

Hi guys! I’m new here and doing a few jobs on our rental before we move out next week.

Without actually being able to go into the store, seek advice and actually look at my options (I’m on Melbourne lockdown), I’m really struggling on what specifically to buy via online shopping.

we have a shallow but quite long crack in our bathroom sink, is someone able to advise exactly what I need to purchase so I can do click and collect?

ie what putty, sand paper, enamel paint? Or whatever I may need?

thank you so much!

Welcome to the Bunnings Workshop community @Kristen79. It's terrific that you've joined us, and many thanks for your question on porcelain sink repairs.

I understand that you are renting and would like to repair any damages before leaving, but if this was an owner asking the same question, I would suggest purchasing a new sink instead. Any putty or paint used excessively is likely to be quite noticeable. We want to make sure that any fix isn't going to make things look worse.

I wouldn't advise painting the whole basin. However, I would be quite happy with you placing a small amount of Selleys 30g Porcelain Fix Premium Epoxy Adhesive onto a plastic scraper and wiping/pushing it into the crack. It will likely fill it up and make it less noticeable. Only use a small amount and try not to smear it over the basin's surface. You could complete a suitable repair by pushing it into the crack and wiping off any excess on the surface. Please note you don't want to apply the adhesive to the surface as although the crack will be disguised, you'll now have "painted" white lines of epoxy.

Let me mention @redracer01 to see if he has some suggestions.

Hello @Kristen79

Welcome to Bunnings Workshop! @MitchellMc 's suggestions are all very sound and pretty much what I would have advised in your situation. But he is absolutely right when he says that instead of hiding the crack it will become even more noticeable. You could use a very fine brush to gently line the crack with the Selleys sealer how ever too much of it becomes obvious. Our goal is to blend and repair the damage.

If you choose to replace the basin it is a bit more involved. In order for you to get a correct fit you will have to bring the sink with you to the shop to compare cut outs and lip overhangs. It is a bit tricky and often not very straight forward as drop basin measurements change from time to time. Once you find a compatible basin you will need to be able to plumb it back in. If you find nothing compatible you may not have an option but to cut a bigger hole in the existing vanity top. This is on the assumption that it is a laminated timber top. You may need the services of a plumber or a registered handy man who has experience doing this. Please keep us informed of your progress and if you have any other questions please post it here on workshop.

Cheers,

MitchellMc suggested (some time back) the use of Selleys Porcelain Fix for such a crack and included a link. That link is no longer found now. I have an old tube of this product and have been looking around for a new one at Bunnings and elsewhere, but it doesn't appear to be available anymore. For what it is worth, I have used Porcelain Fix to patch cracks (due to slight wall movement) in off-white coloured bathroom tiles and it has been very effective at hiding the cracks. But in my case, the cracks had opened up slightly, say 0.3mm so it was possible to smear the adhesive along and into the crack using a blade or scraper and then quickly wipe off the excess adhesive (in a direction lateral to the crack) using paper towel soaked in mineral turps before the adhesive cures.

Hello @MartinG

Welcome to the Bunnings Workshop community. Thank you for joining the discussion.

Thank you for sharing your experience with Selleys Porcelain Fix. It's a good product and hides defects very well. Unfortunately, Selleys has discontinued the product and are currently in the process of making a replacement for it. Looking at the photo you posted, the repair looks neat and is disguised very well. Only if you stop to look and concentrate will you see the crack in the wall.

Hello,

I am wondering what they have replaced this product with to fix basin cracks?

Hi @OC,

Thank you for your question and welcome to the Bunnings Workshop community, it is fabulous to have you with us.

This Rust-Oleum Tub And Tile Touch Up Kit is a very similar product that can be used to fix cracks in ceramic and porcelain basins.

Let me know what you think.

I’m having a same situation for a vanity unit which had been chipped and cracked for around 10 years. I’d like to use Selleys 30g Porcelain Fix Premium Epoxy Adhesive as suggested. However, this product is no longer available in Bunnings. Any suggestions of alternatives? Thx

(PS. It’s a big job to replace this unit. One reason is that I can’t get the exact tiles anymore from around 20 years ago.)

Hello @AC60

There has been no update with Selleys in regards to the Porcelain fix. As an alternative I suggest looking at the PC-11 56g White Epoxy Paste or Rust-Oleum 13.3ml White Tub And Tile Touch Up Kit.

The PC-11 is like an epoxy putty that you can push into the cracks. I suggest using your thumb to fill both the deep and shallow cracks, your goal is to cover and fill the damaged sections with the least amount of epoxy so that you can easily sand off the excess. You can then cover the surface with the touch up kit, please note that the touch up kit although white will not match the exact finish of your basin.

If you need further assitance, please let us know.
