Repair a Chipped Tub

The DIYer

If you have a tub with a porcelain coating that has a chip, it’s not the end of the world, or the end of the tub either. It takes a little work, but it can be fixed without too much effort or cost.

You will need the following:

1- Hair dryer

2- 220 grit sandpaper

3- Rubbing alcohol

4- Porcelain repair kit

5- Plastic putty knife

6- Straight razor

7- Nail polish remover

8- Porcelain touch up paint

Here’s how you do it:

1- Clean the chipped area thoroughly and dry with the hairdryer.

2- Sand the chipped area until all edges are smooth, be sure to not sand undamaged area to avoid scratches.

3- Clean the area again, this time using the rubbing alcohol and dry thoroughly before going to the next step.

4- Apply the porcelain repair as per instructions. Different brands may have different instructions, so be sure to read them.

5- Use the putty knife to smooth it over until it appears smooth and flush with surrounding area.

6- Allow to dry for at least 24 hours, then smoothen the edges using the rubbing alcohol and a cotton ball by wiping gently.

7- If the color doesn’t match, use a porcelain touch up paint to match the color.


1- The same repairs apply to sinks and toilets that need cosmetic repairs. This repair is not suitable for cracks or to seal leaks. Cracked or leaking fixtures should be replaced.

2- Porcelain repair takes time and patience. Rushing it will only make the damaged area look worse, so take your time and you’ll have a good repair when you’re done.
