Of course it is logical for people to fear undermount kitchen sinks, as the typical stainless steel double sink that is only filled to one side with water will weigh approximately 100 pounds. What’s needed is super-strength epoxy. There are metal anchors that are used to anchor the anchors to the backside of your countertop. They are to be epoxied into place with two-part epoxy. Now the bond created by two-part epoxy has to be seen to be believed, but it has been said that the bond of it is often stronger than the items it bonds together. The installer should completely wipe down both the underside of the countertop as well as the sink itself. The reason for this is that there is often construction dust that adheres to these parts, and since dust will not make a good bond, be sure to have it be a very clean surface.


Once the surfaces are cleaned, a bead of silicone caulk can be run along the edge of the sink where it will touch the backside of the countertop. Most people use clear silicone for this, in case any of it oozes out and it may be seen if it’s not colorless, as you do not wish to change that seamless appearance.


The next step to installing undermount kitchen sinks is to take one 2X4 that is longer than the longest part of the sink if it’s a single sink or two 2X4’s if it’s a double sink. A bar clamp is then used for each drain hole found in the sink. The bottom end of the bar clamp goes through the sink drain hole, and the top part of the clamp goes atop the 2X4.


Once tightened slightly, the installer may then check if the sink is placed correctly before doing the final tightening of the clamps. Reaching up under the sink the two-part epoxy is applied to the bolt posts. After about 10 minutes elapses, the rest of the hardware that securely holds the sink to the countertop is placed in place. One should then wait approximately 24 hours to ascertain the undermount kitchen sinks’ adherence.
