Leaving a smooth, attractive line of caulk is a difficult task for me — even when I follow the manufacturer’s recommended procedures. I’ve used rounded pieces of wood and plastic, and my finger, all both wet and dry. The result is invariably a caulk seam of amateur status.
For me, the solution is an ice cube. I take an ordinary ice cube and shape it to a rounded tip using the palm of my hand. Then I wipe down the entire length of the caulk seam with the cube. This leaves a perfectly smooth seam, and the excess caulk is easily removed from the cube. Water isn’t the best tooling liquid for all caulks, though, so check the labels.
