Easy Install
Use exterior caulking or construction adhesive for durability. Some interior caulking can get soft when it is left in the sun.

Add Caulking to Center
Put some caulking in the center of the bucket before you install the Bucket Funnel. This will secure it to the bottom and helps with rigidity.

Add Thick bead around Edge
Try and fill the depth of the recess, so when you smooth it out you do not create low spots.

Smooth It Out
As you smooth it out you may need to add more caulking to keep it flush with the top surface. Now let it dry, and you are ready.
