I've used a tub of furnace cement for fire brick installation. A trick I learned while working with masons in the summer heat was to soak the brick before motaring in place. It allows the mortar, or in this case the furnace cement, to adhere to the surfaces better. I soaked the fire brick in water before trawling on the cement. I also sponged off the mating surface of the stove making sure it stayed moist after it was free of ash. Use a little cement between the brick seams, creating a sandwich with the cement between the bricks. Be sure to smooth off any that might ooze out, you don't need much.
Now, after all that, I read your post again! You can use the cement to smooth out the brick. Use a sponge to wet them good before applying the furnace cement. Let it dry per directions before firring up. A small pointing trawl will do the trick. I kept an oil burner refractory patched with this technique for many years.
