DIY: Porcelain Chip Repair



Do you have any ugly chip or scratch in your porcelain sink or tub?  Why not fix it? There are easy to use porcelain chip repair kits that you can buy.  They make any damage in porcelain, ceramic or enamel surfaces practically disappear.  Look how easy it is to do it yourself!  This is a fun beginner project and it does not cost you much money.

In fact you probably already have the tools you will need around the house.  You will just need to purchase a Porcelain Chip Fix kit. (Which is only $5.00) at Home Depot.  You will see how satisfying it is to make a damaged porcelain sink (or tub) look new again.



Pick up a Porcelain Chip Fix Kit, masking tape, some flat razor blades, and a piece of fine sandpaper from the local hardware store or home center.



Other items you will need that you most likely already have include:


Finger nail polish remover, a small plastic lid from a household item, a long skinny stir stick (I found a wood shish kabob skewer in the kitchen to use).


1. Mix the Epoxy

This porcelain repair is a two part epoxy that needs to be mixed together and allowed to thicken for 25 minutes.

While the epoxy is setting up or “potting” , prep the chipped area you will be filling.


2.  Sand.

The chipped surface needs to be lightly sanded and cleaned thoroughly.  This will ensure the epoxy will get a good bond to the old surface.


3. Clean

Use an alcohol prep pad and wipe the area you just got done sanding clean.  You could also put some finger nail polish remover onto a rag or paper towel to clean with.  Allow a few minutes to dry.


4.  Mask

Use masking tape to mask off a small square around the repair(s) you will be making

5.  Apply epoxy

Use the little brush and apply the epoxy over the chip


6.  Smooth out


Use a flat blade just like a putty knife to smooth over the surface.  Drag the wet epoxy upward.


7. Pull masking tape off


8.  Make final pass


Working upwards, hold a flat blade tight to the surface and let the blades edge cut and smooth over the epoxy.  If you have any product smeared on the surface around the chip, you can clean it off with a rag and finger nail polish remover.  Be careful not to touch the filled area.


9. Let cure for an hour


Update: Have been 6 months since we repair and still looks good.

    thank you this was very helpful! we went to home depot first and they didn’t know how to help us . so glad we found you !

    I wish I had seen this before I did my repair. I had no idea about masking it and smoothing it. Mine is a lump of epoxy. When it is completely cured, can I sand it down?

      I would recommend carefully breaking off what you have done with a sharp wood chisel and starting over. I think it would be very difficult to sand and you would end up with a dull surface.

      Colors other than white are available. But colors between manufactures are different. So, find you sink brand and then search online for “Porcelain chip repair almond” or include Kholer or American Standard. You will find options. Good luck. Thanks for your comment. -Steve

      There are products and companies out there, that offer coatings that resurface porcelain. I personally have never done it. I have seen it done first hand, and was not impressed! I would advise against it. I m sorry I know that is not what you wanted to hear! Good luck
