Penny-pinching glue spreader takes the cake
To minimize the headache of excess glue squeeze-out (which I find both annoying and wasteful), I use a plastic, disposable knife to lay down a perfect film of glue. The serrated edge creates a uniform thickness of glue, similar to a notched trowel for applying thinset tile adhesive. To control the thickness of the glue layer, simply tilt the knife. As an added bonus, dried glue easily flakes off the knife so I can reuse it often.
