Because of the score marks left by the 16 grit discs and to a lesser extent, the 24 grit discs, there is a need to follow up with a 60 or 80 grit finishing disc. These discs will remove the remaining paint and do the final surface preparation ready for painting. In some cases the 60 grit disc will strip softer painted surfaces or surfaces with 3 or 4 layers off just as effectively as the 16 grit disc. Just try them to see how they work in each different situation. Both the 60# and 80# discs have an abrasive edge so that the undersides of the boards are sanded as the flats are sanded. It is false economy to use the 16# then wait for the timber to dry and then dry sand with an orbital. Just get straight in with the 60# or 80#, hose down and the timber is virtually ready for painting.
Because this is a finishing disc used for the removal of score marks this disc achieves at least twice the coverage of the stripping discs.
