I have a white cast iron sink that has a couple of rust stains around the edges. Can I cover them with paint & if yes what type of paint?

    Try removing the rust spots first and then use an epoxy paint if you cannot get the stain out.

    Hi Lil,

    First clean the spot to take as much rust off as possible. I use baking soda and a mix of vinegar & water - a 50/50 blend of each. Once it dries, you can buy some porcelain touch-up paint that will help preserve the sink. It probably won't match perfectly due to wear on you sink but it will cover the rust spots. Experiment and try to feather the edges of the paint to make it look it's best. Wishing you the best. -Linda

    In the UK we have a product especially for this as we still have lots of old houses that need it and it is white enamelled paint in a small bottle with a paint brush attached to the lid, and at first glance quite like nail varnish. So, as I have recently moved to Spain and it’s not sold there, the fact that it looked like nail varnish gave me inspiration. As it was only a little bit on the edge, I bought a good quality nail enamel in white and put a tiny touch on the area very thinly. It needed another coat, so I repeated a thin amount on top. Then I used a nail enamel clear top coat to seal it.

    I did this repair on our bathroom sink 5 years ago and we have difficulty finding the area now as it’s blended so well, and I’ve never had to repeat of the repair..... although I must admit the it is at the back of the sink where it doesn’t get any wear and tear from the children’s hands etc. Unconventional but it worked for us.
