To sand or not to sand?


How do I determine if sanding between coats of compound is needed? I know the pros only sand at the end, but I'm a beginner. How do I know if just a scraping with knife is all that's needed? Thanks.

Well, if it is not smooth to the touch( rub your hand over it) it needs sanding and it will trust me

And no amount of primmer and paint is going to fix flaws.
The key is applying thin coats in the first place so there's less sanding needed.
If it takes four coats instead of three while your learning so be it.
Far better, faster and less mess then having to go back and sand it all off.
Most common mistake I see DIY's make is not making the seam wide enough, the wider the seam the easier it is to make it look level.
For the last coat I often use a 12" wide knife with slightly thinned mud.
The whole goal is to fill in the low spots, not build it out away from the wall.

Run your hand over it if there are ridges use your knife to knock them off, any low places will fill with the next coat. Some of the high spots you may need to sand but shouldn't be many. To sand between coats isn't necessary unless your getting a big build up. If this is happening your using too much mud.
