To choose the best one for your undermount sink clips, consider factors like drying time, water resistance, and bond strength.

By selecting the right epoxy, you can greatly enhance the installation process and the durability of your undermount sink.

Best Types of Epoxy for Sink Clips

When you are considering the best epoxy for undermount sink clips, there are a few factors to keep in mind.

You want something that is strong, durable, and able to withstand the effects of water and moisture.

In this section, we will look at some top contenders for the task.

Two-part Epoxy Resin Systems

One highly recommended epoxy for sink clips is two-part epoxy resin systems, which are known for their strength and durability.

These products typically consist of a resin and a hardener that, when mixed together, create a strong bond with excellent adhesion properties.

An example of such epoxy is one designed specifically for epoxy polymer systems, which are known for their resistance to physical aging, chemical aging, and hydrothermal aging.

Waterproof Epoxy

Another option to consider is waterproof epoxy. It is designed to be unaffected by water and moisture, making it an ideal choice for undermount sink clips.

This type of epoxy creates a secure bond that can resist the effects of water, ensuring a long-lasting hold for your sink clips.

Cure Time and Workability

In addition to the type of epoxy, you should also pay attention to the cure time and workability of the product.

While some epoxies may only require a cure time of around 24 hours, others might take as long as 72 hours to fully cure.

Generally, faster cure times can be more convenient, but it's essential to follow the manufacturer's instructions for the best results.

Choosing the Right Epoxy

When selecting the best epoxy for undermount sink clips, it's essential to consider several factors, such as durability, usability, safety, and price.

Let's discuss each of these factors in more detail.

Understanding Durability

Selecting an epoxy with high durability will ensure a long-lasting bond for your undermount sink clips.

The ideal epoxy should be able to withstand moisture, temperature changes, and the weight of a fully-loaded sink.

Look for an epoxy that has been specifically designed for use in bathrooms or kitchens and mentions its resistance against moisture, chemicals, and heat.

Considering Usability

Usability is another critical factor to think about when choosing an epoxy.

You need a product that is easy to mix, apply, and has a manageable curing time.

Ideally, look for an epoxy that has a straightforward mixing ratio and instructions.

Additionally, consider the working time, which is the amount of time you have to work with the epoxy before it begins to harden.

A longer working time can make the application process less stressful, giving you enough time to adjust the sink clips if needed.

Safety Factors

When working with epoxy, safety is crucial. First, ensure that the epoxy you choose has low fumes or is labeled as non-toxic.

This is especially important if you plan to work in a confined space, like a bathroom, where ventilation might be limited.

Always follow the manufacturer's instructions for usage and wear appropriate personal protective equipment, including gloves, goggles, and a mask.

Price Considerations

Lastly, consider the price of the epoxy when choosing the best product for undermount sink clips.

While it might be tempting to select the cheapest option, it's essential to prioritize the quality and performance of the epoxy.

However, this doesn't mean you need to overspend, either. Shop around for different options, compare their features and prices, and select a product that will provide a balance between quality and affordability.

Application Process of Epoxy for Sink Clips

Before you begin, ensure you have a clean and dry surface to work with.

Remove any debris or grease that may be present on the sink and the countertop.

It's important to also gather all the necessary materials, such as epoxy, sink clips, a mixing tray, and a spreading tool.


Once the surface is clean, carefully mix the epoxy according to the manufacturer's instructions.

This usually involves combining a resin and a hardener in the correct proportions.

After mixing, make sure to apply the epoxy within its pot life, typically ranging from 5 to 30 minutes, depending on the specific product.

Using a spreading tool, apply the epoxy to the flat side of the sink clips, ensuring a consistent layer without any gaps.

Next, press the sink clips onto the underside of the countertop in the appropriate locations.

It's essential to distribute the clips evenly around the sink to ensure that it is secured properly.

If any epoxy residue squeezes out, you can use a clean cloth to wipe it away.

Drying and Curing

Allow the epoxy to dry and cure for the recommended time period, usually between 24 and 48 hours.

During the curing process, the epoxy undergoes a chemical reaction that strengthens its bond and ensures a durable and reliable connection between the sink clips and the countertop.

Make sure not to use or disturb the sink during the curing period to avoid weakening the bond.

Once the epoxy has fully cured, you can safely install the undermount sink and enjoy the benefits of a secure and well-attached sink system.

It's all about understanding which features are most important for your specific situation and considering how well each epoxy can meet those needs.

With the right epoxy, you can trust that your undermount sink will remain secure and in place even after years of use.
