Filling Q3 joints on cut edges.
How to fill drywall.
I fill the original edges as in the video "Finish Filling PRO4 Edges." This is a demonstration of the methods and tools I use for finishing joint filling. I made a mistake by not cleaning the filler before applying the final filler.
When using ready-mixed compounds (bucket mixes) in stages Q1-Q3, I don't modify them. I don't add water to them. Any water I add is used for extended filler (not to be confused with Q4).
Oops, the video fragment of filling with a trowel is an example of filling on a cut edge because, in reality, I do it on the longitudinal edge of the original.
