Apply Adhesive and Bond Bricks Underwater

What happens here

Using a caulk gun loaded with Soudal Fix All adhesive, apply a generous amount of the adhesive onto the top surface of the brick that is submerged in water. Once the adhesive is applied, take the second brick and place it firmly on top of the first brick, pressing down to ensure good contact with the adhesive. Both bricks should remain submerged during this process.

Goal: Bond two bricks together while fully submerged in water.
