While the crews are hard at work on our house construction, my husband has been busy with a cast iron sink restoration. Read all about his progress and see how the sink looks now!

 

It’s been a super busy summer for the construction crews out at our house build site. They are currently finishing up the framing and sealing the exterior. Hopefully, all of that can be finished before the cold Fall weather starts up! In the meantime, We have been cleaning and preparing items that will be used in the new house. Bathroom vanities are getting painted, chairs are being refinished, and the cast iron sinks are getting restored!

We have two vintage cast iron sinks that will be installed in the new house. One is a large, single basin farmhouse sink which will be used in the kitchen. The other is this smaller model 1930’s Kohler wall hung unit, which will be the perfect compliment to our main level powder room.

 

HISTORY OF THE CAST IRON SINKS

Both sinks were recovered from the property we are currently renting, my husband’s grandparents farmstead. They remodeled their house sometime in the 1960’s, and at that time put the sinks outside. They sat for 50+ years in the woods, covered with leaves and debris. Because of this, the sinks definitely needed some TLC.

We talked about hiring a company to do a complete restore, but decided to test out a DIY version on the smaller sink. Once we knew the results, we figured we would be able to make an informed decision about what to do with the larger one.

 

 

CAST IRON SINK CLEANING

First, the sink needed some good old elbow grease. Craig started with very mild cleansers – such as a baking soda/water mixture. Eventually, he moved to harsher chemical cleaners, including ‘Iron Out’ and ‘Bar Keepers Friend.’ While they did clean the sink somewhat, none of the products were completely removing the rust stains.

Craig really wanted to remove the rust, as it could affect the sink’s future integrity if not addressed properly. He ultimately needed to use a wire wheel brush to remove the rust spots.

 

FIXING THE CHIP

Besides the rust, the biggest issue with this sink was a large chip in the enamel, as well as a hairline crack that ran along the side and up the back splash. They were both cosmetic issues, as they did not cause any problems with the sink being able to hold water.

We found an epoxy material that could help fill in the imperfections. Over the course of a day, Craig applied layer after layer, allowing the epoxy to dry between coats. Once the material was above the height of the original enamel, it was left to dry for a few days before sanding.

This product requires a ‘wet sanding’ technique – to help keep the dust down, and to eliminate scratches on the sink’s surface.

 

 

PAINTING THE CAST IRON SINK

We had determined, while cleaning, that the original enamel would need to be covered to get a uniform look. We were in no way looking for perfection, as we understand that this is an old sink. However, the discoloration was pretty bad from the years the sink had sat outdoors.

Once the epoxy had been sanded down smooth, it was time for paint! Craig started by painting the back of the sink with a black ‘rust inhibitor’ paint.

Rustoleum makes a specialty paint product that can be used for bathroom fixtures such as sinks and bathtubs. We decided to give it a try for the front!It goes on about the same as a standard can of spray paint, but the drying time is much longer. This allows the paint to harden.

After three coats, the sink is looking great! The finish isn’t quite as shiny as the original enamel, but it is pure white and uniform. All of the rust spots are covered, and you would need to look extremely close to see any sign of the large chip or crack.

We are quite pleased with the outcome – especially considering the money we saved by doing it DIY style! Of course, until the sink is in use, we won’t know how this paint will hold up over time. I will try to remember to write an update after we have used the sink for several months.
