How To Re-caulk A Kitchen Sink In 5 Steps

We bought our home little more than a year ago.  It’s been great, but it comes with a decent amount of maintenance.  We  learned to do some plumbing, patch dry wall, and some electrical too.

Recently we noticed a black substance peeling away from the sink.  This was great, a new opportunity.  I got to learn how to re-caulk a kitchen sink.  I knew that I had to jump on this issue right away because I didn’t want the cabinets below the sink to get damaged.  Below are the simple steps I took to re-caulk the kitchen sink.

After a year or two the old dark grey caulk line starts to pull away from the sink. After a while the old caulk line will look bad.

Cost: About $10.

You need caulk, a caulk removing tool, and caulking tool to get the job done right.

Step 1.

Using a scraping tool like the Caulk-Away, remove the old caulk.

Scrape of old caulk before adding new caulk.


Step 2.

Once you scrape off the old caulk, clean it away from the surrounding area.

Make sure you clean up the old caulk after you scrape off the old caulk.


Step 3.

Using a knife or a pair of scissors, cut the nozzle to open the tube of caulk.

Step 4.

Run a bead of caulk around seam between the counter top and the sink.


If you cut off too much of the caulk nozzle you will end up wasting caulk and doing more work.

Doh! I cut off too much of the caulk nozzle and the bead of caulk was too thick.

Step 5.

Using a tool such as the Caulk-Rite, run the tool against the line of caulk to remove excess caulk.

This is a finished caulk, use a tool to achieve a smooth neat caulk line.

Tips: Be careful, if you cut off too much of the caulk nozzle you will end up with excess caulk(like I did) on the caulk line.

Follow the directions on the tube of caulk to ensure proper use.  For example, make sure that you wait at least 24 hours before getting water on the caulk line to avoid damaging it.

If your sink needs to be re-caulked, do so quickly, it’s a low cost way to both improve the look of your kitchen and prevent water damage to your cabinetry.  As long as you follow the directions on the caulk tube you will be just fine.
