Caulking a stainless steel sink is easier than other types of kitchen sink materials. In most kitchens, countertops are paired with stainless steel sinks mostly due to their appearance and durability. On any kitchen sink, a lot of cleaning using water takes place, which includes washing dishes, fruits, and vegetables.
One of the problems that can be witnessed is water getting under the sink. Besides this, debris and food particles will find their way beneath the sink. This simply means there is a dangerous leakage.
At times, it can be easy to pinpoint the source of the issue and in some scenarios, this is not possible. To avoid it when using a stainless steel kitchen sink, it is vital to caulk it.
6 Steps to Caulk a Stainless Steel Kitchen Sink:
Caulking is about sealing the kitchen sink to prevent leakage. For the project to be successful, you will need to follow some steps and use some specific tools. Rubbing alcohol, a rag, and caulking gun are all important.
Step 1: Clean the Countertop
Before you can start caulking around a stainless steel sink, you need to clean the countertop. If there is old caulk from a previous sink, it needs to be scraped off.
A sharp object such as a knife or single-edged razor blade would be ideal. If there is no previous sink or when you have scraped off the old caulk, you should clean the countertop using the rubbing alcohol. This is important as it eliminates residues that inhibit successful caulking while at the same time disinfecting it.
Step 2: Trace the Sink Outline
It is paramount that the sink fits accurately and firmly on the kitchen counter. Tracing the sink outline is a crucial step in making sure that the caulking is a success. At this point, lift the sink a few inches so that the caulking gun fits below its edge.
You need to apply several beads of the caulk on these edges and it should be enough to hold the sink firmly. This is to make sure that, there will be no movements once the sink is laid down on the counter.
Step 3: Put the Sink in Place
Once you have applied the caulk, the next step is to place the sink back on the counter. Make sure you are gentle while doing it to avoid a messy finish.
Apply a little pressure for better placement. You may see some excess caulk when the sink is in place, and you should wipe it out using a rag. If you need to secure it using screws or nuts, you can do so at this point.
Step 4: Trace the Sink Again
All the edges of the sink need to be fully sealed and this is the reason it is critically crucial to add the caulk. Lift the sink to fit it in the nozzle of the caulking gun and apply about a quarter bead of the caulk.
You can opt to use a finger to fill in the gaps. Avoid overdoing it and for a professional, smooth application, remove the excess caulk using a rag.
Step 5: Let the Caulk Dry
The caulk must dry up fully before the sink is used otherwise, the results will not be appealing. Water will damage the caulk which is not something you want.
For it to dry up completely, you should wait for 72 hours or more. If it is used before drying up, there are chances there will be gaps in the caulking which means with time there will be water leakage.
Step 6: Check the Finishing
You must make sure that the finishing is successful. You can tell this after 72 hours of drying. Check whether there are gaps or holes, and if there are any, they need resealing. You can use water to test whether it will run under the sink.
