interior tuck-pointing completed

Wetting the joints before the mortar is applied.  The initial absorption rate of these bricks is quite high, as they are bone-dry.  This actually worked out pretty well with the Type-N mortar, mixed to the proper consistency.
The before looks like bad dental work...

We needed to temporarily hold a flexible form (an old kitchen cutting mat) for a few minutes while the mortar set.  It took only a few minutes for a full joint, and slightly less for the partials.  Then we tooled the joints.

These are disposable piping bags which can be obtained from a bakery supply store.  Just Snip the tip, and pipe away.

You can also use a masonry bag--basically a reusable cloth pastry bag.  This video on youtube is worth a watch for technique.

We really did not think it was necessary to grind out all the joints--most (80%+) were sound. I Just raked out the softer crumbling ones to about 3/4" to 1" depth, and we applied the mortar to those. 

Finished arch.  I am still debating placing a lintel just under the arch, which is why i did not repair/replace those bricks.  If no lintel, then I'll fill those bricks in when I frame out for the window.

Looks good as old!  ;]
