Plastic Tips for foam gun*: -I didn’t mention this in the video, but you can use these to protect the tip of your foam gun when working against an abrasive surface like concrete, brick or stone. These will lay a very small thin bead of foam. If you need a larger foam bead, simply cut off the tip for a wider diameter.
