The smaller knives (7″ – 18″) can be used with a mud pan to both apply and wipe off excess material. To use these smaller size knives with a mud pan, simply pull the material out of the pan and apply. Cleaning or wiping the knives is easy! Wipe off the material edge of the knife on the inside of the mud pan. The larger knives (24″+) will generally not work well with mud pans as there are not many mud pans larger than 24″ in size. For these sizes, you will need to clear your knife with another knife into your bucket or separate pan.
