I pay people to do this stuff. I know my limitations, and they are many!
Contrary to what is usually stated by the manufacturers, I find Joint Compound to be better than Spackle. In my experience Joint Compound is more crack resistant and just works better. Just my personal experiences.
I rarely if ever have to do any sanding - I just use a damp sponge. The KEY to a good job (took me years to learn) is do at least 3 thinner coats and do NOT try to get the first coat perfect! Feather out the edges and never try to do a job in just one coat - it's impossible to get everything perfect with a single coating.
The best joint compound used to be saliva.
Can you share a video of the process? Load it on youtube and make money off it.Pffffttt. Just look at my screen name. 45 years in the bizness.
Never sanded a wall yet. Go to level 5 finish, skim coat and then wipe with a damp sponge. The end result is better, the amount of extra mud used is insignificant, and the results are better.
