   Sack rub (sack finish)

   A finish for formed concrete surfaces, designed to produce even texture and fill all pits and air holes. After dampening the surface, and before it dries, a mixture of dry cement and sand is rubbed over it with a wad of burlap or a sponge-rubber float to remove surplus mortar and fill the voids.

   Sacking

   Removing or alleviating defects on a concrete surface by applying a mixture of sand and cement to the moistened surface and rubbing with a coarse material such as burlap

    

   This was a new one to me so I just used Ask.com

   Hope this is what your looking for

    

    No one should regard themselve as "God's gift to man." But rather a mere man whos gifts are from God.

   It's kind of similar to "Teabagging".

   See if you can find some pictures of teabagging, you will get an idea of what sacking is.

   So i wouldnt actualy pull my forms with the concrete still soft and rub it. i could wait a day as i normaly do and then "sack" it.

   Does the concrete need to be "cured" before this is done?

   I always used "parging" as a term for water proofing.

   You can "rub" it when the forms come off.  If you have a bucket of water and a little Portland slurry, you can use that to lube the rub block.

   Like I said, I'm no mason, but I've done it...

   I always thought it was called "parging."  Make a slurry of sand and Portland and apply it to a wetted down concrete or block wall with a coarse brush.  I'm no mason, but I've done it that way many, many times.

   Parging

   Portland cement plaster applied over masonry to make it less permeable to water No one should regard themselve as "God's gift to man." But rather a mere man whos gifts are from God.

   Hve never heard the term sacking. I heard of parging but mainly it just "RUB" " you need to rub the wall" or "It gets a rubbed finish"

   "Sack and Patch " on crete... any type of pour, patch holes and defects, to bring it up to a higher grade finish. "Parging" on cinder/concrete block....to give it a smooth appearance Those are the terms/difference used around here.

   Sounds like a process we called "bagging" when I worked in architectural precast concrete. A little bit of the design mix minus the aggregate was set aside (dry) and later mixed with a little water and rubbed over the piece with a piece of burlap to fill voids and pockets. Appearance was extremely important with the components- lintels, sills, quoins, walls among other things.  "Bagging" was preparation for the final finish- it wasn't the end of the process. An acid etch was the most often used finish. Others were brushed or rolled on retarder applied in the form on on the casting table for an exposed aggregate finish and sometimes sandblasting.
