It depends on what type of plug compound the driller uses. Some of the quick set types will harden quickly enough to allow a full job to be done in less than a day. The longer set types take a day each for the thumb and fingers, or two days total. I personally like to give each area plugged at least two days, so I take a total of three days to do a complete job. I have never used the quick set resins myself, but have heard other drillers say that they are not totally satisfied with the final job using them. -- JohnP
