So I have this concrete wall between the old house and a small addition put on sometime in the past. We have torn out the flooring layers in the kitchen and we are having the wood refinished there. In the butler’s pantry, we are pulling the wood to use for patching in the kitchen, and putting new wood in the pantry.
In the addition area, we are going to tile, after pulling up a layer of plywood so that we can keep it level with the wood.
The problem is this 9″ by 31″ piece of the original exterior wall. We will tile over this area also, but we need to remove about 1 inch of it to maintain level. I was thinking of kerfing it with a masonry blade on a circular saw or grinder, then chipping out the pieces. Can’t use a wet saw. I figure I have to go a bit deeper than the floor level, and then use some floor leveler to get back to the proper height.
Anyone got any alternatives, or will my way even work?

I'd cut it down low enough that you can run the tile substrate over it as well. If you run cement board or whatever up to the concrete and then tile over both of them, you're likely to get a crack due to differential movement between the two substrates.

Any treatment that bridges the junctions will crack.
Add a decorative stone sill. Marble, granite, etc. Tile to the sill.
I'm not sure I follow why it would crack. My plan is to cut down about 1 1/4" to 1 1/2" since I know it will be uneven. Then I'll add some floor leveler or probably just thin set to bring it to the level I need to install 1/2" hardi board across the whole area, followed by the tile.I'm pulling a layer of plywood and vinyl from the area to be tiled, so that I can get the area at a constant level.

Movement.
Cementious materials don't move the same as wood products. 0.001" difference in movement and you will have a crack.
install 1/2" hardi board across the whole area, followed by the tile.
That will stop cracks, but I would use a Liquid Nail type product to adhere the Hardi-Board to the cement wall-ette because the glue will allow some differential movement while still providing support for the area.SamT
Try misting a little water on it with a weed sprayer. Just keep it damp, that will really cut down on the dust. We jackhammer out pretty big chunks of concrete around nightdrops in banks and the misting technique works wonders.

Thanks! I hadn't thought about just misting, but that I can do.How far apart should I make my cuts? What brand or type of blade do you suggest?
I like those small chipping hammers you can rent. take all of a hour time.
For the little bit you have to do any of them will work. Just score the crap out of it and then chip it out witha chisel or a small electric chipping hammer
