How To Remove A Kitchen Sink That Is Glued Down

Removing a kitchen sink that is glued down can be a daunting task. But don’t worry! With the right tools and a bit of know-how, you can have it done in no time.

In this guide, you’ll learn the steps involved in removing a glued-down sink, from preparing the area to preparing the new sink. With a few simple steps, you’ll have that kitchen sink out of the way in no time!

Preparing the Area

Before you start your project, make sure you clear the area around the fixture so you can easily access it and have plenty of room to work.

Remove any items sitting on top of the sink, and clean the surrounding countertops and surfaces. This will help you work freely and prevent any dust or debris from getting inside the sink.

Additionally, it’s a good idea to shut off the water and unplug the garbage disposal before you start if your sink features one. This will help ensure that a water pipe doesn’t burst and cause a mess while you’re working.

Removing the Faucet and Supply Lines

Alright, let’s get this faucet and those supply lines outta here!

The first step is to disconnect the supply lines from the shutoff valves. Make sure to loosen the nuts with a basin wrench and unscrew the connections that are connecting the faucet with the sink.

After that’s done, you’ll want to loosen the mounting nuts with a basin wrench that’s holding the faucet in place and then pull it up. If the faucet was installed with sealant, you’ll need to use a putty knife to help pry it away from the countertop.

Finally, you’ll want to install the pipes and add sealant to the underside of the sink to secure it to the countertop.

Cutting the Caulk

Excitingly, it’s time to cut that caulk and get your kitchen sink unstuck!

In order to do this, you’ll need to clean the caulk first. Start by using a putty knife or razor blade to scrape away any dried or loose caulk. Once you’ve removed the loose caulk, use a caulk remover or cleaner to ensure that the surface is clean.

After that, you’ll need to apply some fresh caulk to make sure the sink is properly sealed. Use a caulk gun to apply the caulk and make sure to smooth out the lines with a damp cloth. Once the caulk is dry, you should be able to remove the kitchen sink with ease.

Breaking the Seal with a Pry Bar

You’re ready to break the seal and free the sink from its glued down state – all that stands in your way is a pry bar.

To begin, use a lifting technique to carefully slip the bar between the sink and the countertop. This will help to break the seal, but it may take a few attempts. You can also use a scraping solution to help loosen the seal.

Once the seal is broken, you can pull the sink away from the countertop.

Here are a few tips to keep in mind when using a pry bar:

  • Make sure to use gentle, steady pressure when prying the sink away from the countertop.
  • Try not to use too much force, as this can cause damage to the countertop or sink.
  • Wear safety glasses or goggles when using a pry bar.

Using an Electric Saw

With an electric saw in hand, you can now easily separate the stuck-on sink from the countertop. Before you begin, make sure to read the instruction manual and take all necessary safety precautions when installing the saw.

Wear a face shield, protective gloves, and safety glasses, and make sure the area is well ventilated. Also, make sure the saw blade is firmly mounted and the blade guard is in place.

Once the saw is set up and the safety precautions have been taken, you’re now ready to start cutting the sink. Move the saw blade slowly and steadily along the edge of the sink, taking care not to damage the countertop material.

Once the seal has been broken, remove the sink from the countertop with a pry bar. Be sure to use a firm grip and keep your body at a safe distance from the saw as you work.

Removing the Glue with a Heat Gun

Now that the sink is off, you can use a heat gun to gently melt away the adhesive keeping it stuck down. Heat guns are a great tool for paint stripping and can be used to dissolve the glue used to secure the sink to the countertop. The heat gun can be adjusted to the right temperature to soften the adhesive without damaging the countertop.

To use the heat gun to remove the glue, start from the edge and work towards the center. Make sure to keep the gun moving in order to prevent overheating the countertop.

You may also want to use a chemical solvent to further dissolve the glue, but be sure to wear protective gloves and eyewear when using the solvent.

Before placing the sink onto the countertop in its final location.

Preparing the New Sink

Having prepped the countertop, it’s now time to ready the new sink for installation.

Choosing the right materials is an important part of the installation process. Consider the size of the sink, the materials it’s made from, and the type of fastening hardware you’ll need.

Be sure to check the manufacturer’s instructions for the sink and hardware, so you know exactly how to install them. The hardware you select should match the specifications for the sink and the countertop.

This includes fasteners like screws, clips, and mounting brackets. You may also need sealants and adhesives to provide a watertight seal between the sink and the countertop.

It’s important to use the right materials and properly secure the sink to ensure a long-lasting and leak-free installation.

Frequently Asked Questions

What kind of tool is needed to cut the caulk?

If you need to cut the caulk holding down your kitchen sink, you’ll need a sharpening tool to get the job done.

Depending on the type of caulk you’re dealing with, you may need to use different sharpening tools. For example, if you have a silicone-based caulk, you’ll need a sharpening tool that can easily slice through the silicone.

On the other hand, if you have a latex-based caulk, you’ll need a tool that can cut through the latex without damaging the sink.

What is the best way to protect the countertop while using a pry bar?

When using a pry bar to remove a kitchen sink, it’s important to protect the countertop from any damage.

The best way to do this is to waterproof the surface and cover it with a protective material.

If the countertop is made of wood, you might consider using a wood sealant and then lay a thick cloth over it. This will help protect it from scratches or chips caused by the pry bar.

Alternatively, you can use a rubber mat or a piece of cardboard to protect the surface.

Make sure to use the right amount of force when using the pry bar and to be careful not to damage the countertop.

Is there an alternative to using a heat gun to remove glue?

You don’t need to use a heat gun to remove glue from your kitchen sink.

An air chisel is a great alternative to consider. This tool can be used to chip away the glue and other material to free the sink.

To ensure that your countertop is protected, you should also use some waterproofing sealant to avoid any potential damage.

What safety precautions should be taken when using an electric saw?

When using an electric saw to cut through any material, it’s important to take safety precautions for your own protection.

Always wear protective goggles to shield your eyes from flying debris and use a drill to make pilot holes to prevent the saw from slipping.

Additionally, make sure your workspace is clear of any items that could be hazardous.

Keep the saw blade sharp for accurate and safe cutting.

What type of sink is best to replace a glued-down sink?

Replacing a kitchen sink that’s glued down can be tough, but there are plenty of adhesive options and sealing techniques to make the job easier.

You should consider a few factors when choosing the best sink to replace your glued-down one. For example, think about the sink’s size and weight, the amount of adhesive needed to secure it, and the ease of installation.

It’s also crucial to pick a sink that’s durable and easy to clean. Finally, ensure that the sink you choose is made of a material that’s compatible with the sealant used to secure it.

With these considerations in mind, you can be confident that you’ll find the perfect sink to replace the glued-down one.


Great job! You’ve successfully removed your old kitchen sink that was glued down.

Now that it’s out of the way, you can replace it with a new one.

All you have to do is prepare the new sink by cleaning and prepping the area, install the new faucet and supply lines, and then carefully place the new sink into the countertop.

With a few simple steps, you can have a brand new kitchen sink.
