Mr. Suez along his kitchen nook had only one section of backyard brick wall that needed to be repaired. He wanted a quick fix because he had sold the house. It appeared that two of his sprinklers were facing the bricks. The middle bricks had started to deteriorate. Part of the repair was to insert new repair patch within the brick wall and the other part was to apply a sealer coat to the brick area.   

This post shows the six steps to repair this problem. 

Step 1: Fig.1 shows the removal of all debris, plant and garbage near the wall area. Scrape out loose bricks and loose mortar.
Step 2: Fig.2 shows a manual caulking gun that will be used to apply missing mortar on the seams of the brick wall. Fig.3 shows a 2-inch brush that will be used to cut around the red brick area.
