Best Adhesive to Glue Sink to Kitchen Worktop or Unit

To glue sink to a kitchen worktop or bathroom unit, using Adiseal adhesive will provide a high-performance bond. Adiseal provides a strong, flexible, waterproof and durable adhesive bond when attaching sinks. Adiseal has also been shown to be the strongest adhesive in an independent adhesive strength test.

Adiseal provides high-strength bonds on sinks made from many different materials including metal, ceramic, granite and marble to wood worktops as well as other materials. Whether attaching the sink undermount or sitting on top of a kitchen worktop, Adiseal is the best adhesive to fit a sink.

Best Adhesive Strength Test

Ultimate Handyman conducted adhesive strength tests by applying various products between wood and metal surfaces, then subjecting them to pressure after curing. Adiseal emerged as the strongest adhesive, exhibiting strength three times greater than its closest competitor. Its exceptional resilience nearly caused the test rig’s screws to tear out before the bond broke, leading to the premature termination of the test.

Test results

Adiseal displayed remarkable durability, enduring pressures that exceeded 3123 psi in the bond strength test conducted between hardwood and metal. In contrast, every competing product’s bonds weakened at pressures of 1115 psi or less. The associated graphic underscores Adiseal’s outstanding performance, reaffirming its status as the foremost adhesive in its class.

How to attach a sink with an adhesive

How to attach a sink with an adhesive

  1. Surface preparation

    To get a good adhesive bond, making sure both surfaces are clean is very important. Wipe away any dirt, grease and dust.

  2. Apply adhesive

    Apply the adhesive to the sink. Cover as much area as possible to get a good bond but not too much that excess adhesive squeezes out when the sink is pushed together with the worktop or unit.

  3. Remove excess

    If any excess adhesive squeezes out, remove it before the adhesive cures.

  4. Temporary supports (if required)

    Use temporary supports if required to hold the sink in place until the adhesive cures. These temporary supports need to be removed once the adhesive cures.

  5. Test bond strength

    Apply some pressure to the sink to test the adhesive bond strength.
