     Around here knockdown & Popcorn 2 different types of texture. For knockdown you can use joint compound. But IMHO bagged texture (which can be found @ the Big Boxs or any DW supply house) works much better. Additional binders & such in the bagged stuff, which makes it Ezer to use.

    If you use the bagged goods make sure you mix the way the bag states, amt. h20. Biggest problem I have seen is people not letting the mix sit for a bit. When we can, we mix the night before & then the same batch gets remixed before use

   the knock down effect is what I'm looking for. Applied with a splatter pattern and then trowled down.  Would you recommend regular joint compound and if so how much water would you add to the mix? just enough to allow it to flow nicely from the hopper?

     If you have'nt done any texture in a while, I would go with the bagged stuff. How big of a compressor are you using? The amount of air flow is also a key to good results. If your air runs low the texture could get Sloppy. I like to have at least 30psi when I spray.

     If you run low just wait for the air to catch up! I will run out to the shed & see if I have a bag that I could post a picture. I Have also had good results with the stuff Home Depot sells.

     If you do use joint compound I would mix it to something thicker then pancake batter. You also need the right touch when knocking down (go lightly when knocking down).

     What I like about the bagged stuff is the fact that I have a larger open time  for the knockdown step.

     Best bet would do the closets first to get in the swing of it. If you run in to problems & your not trying to match a texture, you can always re spray an area after it dries & hide the problems.

     The drywallers around here all like the Knockdown texture, because they say, "It Hides a Multitude of Sins!"

     Remember to de-bur the walls before you paint (knock-off or light sand the fuzz & burs when 100% dry).

   Very helpful thankyou. I would love to see a pic of the bagged stuff. I have never used or seen it before. The ready-tex product that I was using was a lot like regular mud. I had a sneaky suspicion that they were two of the same. I will be using my MakAir compressor for the job, i don't think I will have a problem with it keeping up. 30 psi sounds good,  I used to run just a little less than that, but it will depend on the batch i think

   If you'll pay the shipping, I can fix you up with all the old, used, popcorn you can handle.  People here in CA are scraping it off by the ton and it can be had cheap - lol.

   Dont know if the above is the same product as you used before (or if my cut&paste link even works!!) but the the site has lots of info/product data http://www.cgcinc.com

   I do lots of ceiling patching and use Synko brand textures (dry form) available from GWB suppliers. They will have, or be able to get what you need.

   I spray with small gun (not the hopper-type) using my AIRPAC compressor. This is adequate for small areas/rooms. As mentioned, low PSI but high cfm req'd.

   Happy Splattering
