How to Install Undermount Sink Without Clips : Step by Step

Let’s see the step by step process to install undermount sink without clips .

1. Cleaning

When installing your kitchen sink with adhesive, it is essential to clean both the countertop surface and the sink surface that will come into touch with each other during the installation process.

Cleaning your surfaces with acetone and a clean cloth eliminates any filth, dirt, oil, and other contaminants that may impede the cleaning process. Whenever you are using this product, you must adhere to all of the directions and precautions stated on the acetone bottle. Immediately after cleaning, let the sink surfaces dry completely, which typically takes just a few minutes.

2. Apply Adhesive

When purchasing an adhesive, it is important to use the finest glue available so that your sink will remain precisely aligned with the countertop for an extended period of time.

Although many readily accessible adhesives on the market are also appropriate for kitchen sink installation, clear or crystalline silicon is considered as the industry standard. It is superior to other kinds of adhesives in terms of strength, and it is also used to seal the area surrounding your Undermount sink once it has been installed.

In order for the sink and the countertop to connect, the sink must have a contact surface.

When your sink makes touch with your countertop, this is referred to as the “contact surface.” A silicone bead or cord is wrapped around the contact surface of your sink.

For an under-mount sink, the contact surface is typically a 1-inch lip on the same side of the sinkholes as the sink openings themselves. Drop-in sinks require silicone to the bottom of the sink’s perimeter, which is the opposite side of the sinkholes.

3. Installation

You must install the sink at the bottom of the countertop if you wish to use an under-mount sink installation method.

Before applying the glue, the installers must first put the sink in the cabinet under the aperture for the sink. Next, your sink is lifted until it makes contact with the bottom of your countertop after the silicone glue has been applied.

Depending on the number of drain holes in your sink, 1-2 bar clamps and a cross bracing will be required to secure it in place. One end of the bar clamp is attached to the bottom of your sink via the hole for your sink drain, and the other end is secured to the cross-bracing of your sink.

Next, the installer adjusts the location of your sink and tightens the bar clamps until your sink is flush with the surface of your counter. The clamps will stay in place until your silicone has hardened completely.

Drop-in sinks are more easily installed than their under-mount counterparts because they are more accessible. Next, the adhesive is applied beneath the lip of your sink, which is then lowered into place and adjusted to its proper position.

4. Washing

Both drop-in and Undermount sinks need immediate cleaning following installation to remove any excess silicone from the sides of the sink.

You have to eliminate the extra sink edges and debris from the surface of them. A tiny amount of silicone oozes out from below the sink edges when you tighten the clamps.

Before removing the extra silicone, connect the sink lip with the surface with your finger to make sure that they adjust correctly. If you believe you need to apply more silicone, go ahead and do so, removing any excess silicone with a cloth and acetone before it hardens.

After you have cleaned the surface of your sink, it will seem flawless, clean, and glossy.

5. Epoxy

The last step in installing an Undermount sink without hardware is to provide additional support for sinks that have a trash disposal system.

Filling your sink with water may put a tremendous amount of pressure on the trash disposal sides, causing your sink to come loose from the countertop. Adding extra support to your sink will decrease the likelihood that it will get dislodged from its countertop. –

The expert installers will connect tiny pieces of granite or acrylic material to the underside of your countertop using two-part epoxy. It will help to overlaps the lip around your sink. Because your epoxy is a highly fast-setting substance, it also enables the installer to join the piping immediately after your sink installation, which would not have been feasible if you had used your silicone instead.

Using your epoxy and blocks with a drop-in sink is not essential since the countertop supports the sink.
