The top 9 courses of brick are in a considerable state of disrepair. After much discussion and evaluation, it is my opinion that the brick used at the parapet on the alley side are softer than those used on the other faces and they tend to absorb water more. This has resulted in the faces of many brick spalling off and significant deterioration of the mortar joints. While we do not feel this location justifies the expense of replacing the damaged brick and tuck pointing the mortar joints, we do have considerable concern about how well the new paint will adhere to this area and how long it will hold up. We propose to improve the face of the parapet by the following method: The area to be treated is the top 2' of brick by 176' long. Power wash with rotary tip to remove all the loose particles. Pre -wet wall with Tammsweld liquid bonding agent. In -fill mortar joints and missing brick faces with Tamms Thin Patch polymer- modified, cement based mortar formulated for repairing defects in concrete and masonry surfaces from featheredge up to 1 ". This will result in a relatively smooth surface (similar in appearance to the cast -in -place concrete beam directly below the brick parapet) that will encapsulate the existing brick and mortar joints into a significantly more stable surface for the paint to adhere to. This should prevent or minimize future spalling of brick as long as the back side of the parapet is properly flashed to the roof of the building.
