Repair Mortars

How do you fill mortar between bricks?

Scoop a dollop of mortar onto a brick trowel or hawk, hold it up even with a bed joint, and push the mortar against the back of the joint with the tuck-pointing trowel. Eliminate voids with a few slicing passes of the trowel's edge, then add more mortar until the joint is filled.

How do you fix cracked mortar?

If the cracked mortar is harder, make a relief cut down the center of the mortar joint using the pointed edge of the chisel and then gently chip out the mortar (brick grout) that contacts the brick. If the removal work is going really slowly, use an angle grinder to make the relief cuts.

How do you repair concrete mortar?
