Kitchen cabinets, sinks, baths- these are the tools constantly exposed to water, hence getting damaged and mildewed. Damp feelings! Isn’t it?

Indeed, there are available products to eliminate this dampness, such as varieties of putties, caulks, and sealants. But if we talk about silicone among them, undoubtedly it’s the best one.

To protect your sink from water damages and mold, you should seal its rim with a good bead of silicone caulk. But what types of caulk you needed? Which brand? Why won’t you go for others? – These all are the questions that make a buyer confused, suitable? We think so!

Hopefully, this article will disclose all your confusion about using silicone caulk for the kitchen sink and help you get proper guidance.

What Kind of Caulk to Use For The Sink?

Indeed, it’s challenging to know which types of caulk or sealant would be the right one while plenty of products are available there claiming to be the best for specific applications.

Well, in that case, you need to point out the problems according to your project. For example, your project may need a specific temperature range or water-resistant ability and reliability. And these asked attributes would help you to find out the desirable types of caulk.

Let’s see what the troubles your sink generally faces are.

  • It remains wet most of the time
  • Water builds up around it
  • Water leads to soap scum and molds on the rim.

So, to troubleshoot these problems, you need a caulk that would be

  • waterproof
  • Repels moisture
  • Resistant to mold and mildew
  • Have good adhesive properties
  • Designed for resilient flexibility

Now it’s time to disclose the desirable caulk or sealant that can provide all the above attributes. Here, the pure 100% silicone caulk is the most recommended one and the best solution.

Depending on your sink type (drop-in or undermount), you need to choose the caulk as well.

However, if you are looking for protection against water damage and mold growth, saving energy, 100% silicone is an excellent choice.

Is It Better to Use Silicone or Plumbers Putty?

Plumbers putty and silicone caulk are the most commonly used products in sealing leakage and plumbing. Also, both of these are good enough for this job.

None the less we would recommend you to use silicone instead of plumbers for dealing with the disrupting sink.

You are wondering – why is that?

Well, here are some issues why you should use silicone caulk in particular applications-

  • Plumber’s putty doesn’t give adhesive strength, and it remains soft while silicone forms in a hard texture. So, if you require a strong bonding for your project, you should avoid putty.
  • Silicone adhesive can be used in a large number of applications also in more significant projects. On the other hand, a plumber’s putties are suitable for sealing a small area.
  • Both of these products are waterproof intact. These are built for resisting water, right? Of course. But, for its rigidity and strength, silicone can deal with heavy water pressure and last longer.
  • The plumber’s putty doesn’t seal the space between the wall and sink.
  • Silicone caulks come in a variety of colors, from clear to 23 different light shades. Unfortunately, as the patties aren’t visible after applying, you can’t use them in exposed areas.

Of course, a plumber is more durable than silicone, and it keeps its elasticity. And the maintenance of this product is more accessible than the silicones’.

But if we talk about the rigidity, resistant capacity, and multi-purpose application, you know, it’s silicone caulk – the best solution.

Maintenances of Silicone Caulk

As silicone is a sticky material and becomes hard after drying, you should maintain it in a relatively tricky way. For example, you need extra tools or techniques for a clean outcome while applying or removing the product.

Let’s see what tools and techniques you need to apply while dealing with this adhesive are. Shall we?

Removing the Old Caulks

What you will Need-

  • Flat razor blade/putty knife
  • Angled blade
  • Paper towel and rubbing alcohol

What you will Do-

  • Position the knife to the bottom of the old caulk and slice it slowly.
  • You should keep the knife flat so that it won’t scratch the sink base.
  • While scraping, don’t go too deep. Try to keep it 1/8 to 1/4 inch into the gap.
  • Use an angle of the knife to cut the caulk from the sink downward as well.
  • Alternate between the flat razor and angled blade to remove as much of the old caulk as possible.
  • Use the same technique to remove the old caulk from all around the sink.
  • Also, you can use a caulk remover around the rim in case it seems so hard.
  • After removing the caulk, clean the area with a paper towel soaked in rubbing alcohol. It will make your surface ready to get the new caulk.

Lastly, leave it to air dry altogether before starting the further application.

Applying New Silicone Caulk

What you will Need

  • Painter’s Tape
  • Knife
  • Caulk gun

What you will Do –

  • Tape The Sink Edge

Use the painter’s Tape to the countertop leaving a little space to the gap. Make sure that the gap is visible and accessible.

You can tape both to the countertop and the side of the sink to get the best finishing result. Be careful while taping the corners; it should be the shape of the sink.

  • Prepare The Silicone Caulk

Cut the caulk nozzle with a knife at a 45° angle close to the tip so the tube fits tightly against the rim.

Don’t cut the caulk tube too large as it will make the caulk come out too much at once. Instead, insert the caulk tip into a sealant gun and test its flow on a Scarp material.

  • Apply And Smooth The Caulk

Point the tip of the tube into the space between the sink edge. Squeeze the caulking tube gently but firmly, pulling the tube toward you. Maintain the smooth continuous motion with a steady flow to create a smooth layer.

While it comes to smooth the layer, you can use flat smoother like a silicon tool to get a perfect finish.

Well, in this case, you are using painter’s tape for the same purpose; then would you need a smoother again? We don’t think so! Let your finger do this job!

  • Remove The Tape And Let it Dry

While the caulk is still wet, pull the tape off the sink. You should see a clean and straight line of silicone caulk all around your sink.

Avoid applying water into the sealant until it’s scorched. Here’s to mention that different caulks come with a different range of drying time; you will find it in the manufacturer’s instructions.

That’s it! Your sink is now safe with silicone and ready to go.
