How much sanding

Hello people:
I am renovating my house (everything from foundation to roof), 50 year old foreclosure. My question is this, I just mud and taped on my joints twice, I have also done some sanding. I plan on slapping knockdown mud on with a crows-foot-brush. My question is how much do I need to sand before I start applying texture.

Thanks guys

I would suggest you skim a 3rd coat on any areas that look like they need it with a wide knife to kill any rough edges. If you do that, your sanding should be minimal.

Place a 2' or 4' level across those joints to see if they are flat. Even with the knockdown, major bumps may be visible. If the bumps are too high, your call, sand the high areas (don't expose the tape) and skim coat on each side.

Here is a good overall article for new home owners.

Like X, I always go three coats so one more would be in order for me as well.

Big chunks can be knocked off with the knife rather than sanding, should you have any.

While many pros can get by with only 2 coats of mud on ceilings that will be textured - 3 coats is best! Shining a bright light and viewing the drywall from an angle can be helpful in spotting defects in the finishing. Remember it's a lot easier to fix any bad spots now than after you've textured/painted.
