![]() However, it is not necessary to use the same exact mix/type of mortar nor finish of the joint as it may be too costly, an owner needing Building Renovation may change it at his/her discretion for a variety of reasons, materials may not be available, etc. lime putty) or a mix with portland cement and/or a more modern mortar such as type n, then it can be matched exactly or very closely with that same mortar. When doing a Building Restoration or Historical Preservation, if one wants to be certain about what the existing mortar is exactly composed of then removing a small section of the mortar and having it analyzed/tested by a lab is a fairly easy and inexpensive option. It is not a matter of if there will be failure in the mortar, mortar joints and/or masonry facade but when. This will save the owner the greater expense of masonry unit replacement while only having to repoint the mortar joints when they do fail. brick, stone, block) and when there is movement in the wall/facade/structure it will move and crack before the masonry unit(s) will. Type n mortar is, arguably, the best of the modern mortars to repoint with in most applications as it is usually softer than than the masonry units (i.e. Type n, o, and m mortars are the most commonly used today. For the last half century, modern mortars are made with more basic cement (and/or portland cement) and typically are ready-mixed and, while easier and cheaper for use, they typically do not last as long as lime based mortars found in older buildings. Older buildings in the United States that pre-date the early 1900’s usually are lime based mortars, while after 1900 portland cement was widely used in mortars. Because tuckpointing can be a very complicated matter when deciphering exactly what type of mortar mix is best for the re-pointing process and it is an elaborate process it is better termed re-tuckpointing or, simply, repointing. It involves removing the old existing mortar, preparing the joints properly for re-pointing, tuckpointing, and finishing the joints to match as close as possible the existing joints in terms of type of mortar, color, and the finish of the joints. To make it look neat, we make sure that the lines we produce are as straight as possible.Tuckpointing (also spelled as tuck pointing and/or tuck-pointing), used in Building Restoration, Historical Preservation and other masonry repair projects, is the process of removing old cracked, spalled, or failed mortar in the joints (both head and bed joints) between masonry units such as brick, block, stone, etc. Step 6: When the new mortar starts to harden, we use a straightedge and a tuckpointing tool to make straight lines in the center of the joints. Depending on your request, we may also give it a slightly indented look. Step 5: After applying the mortar to the joints, we smooth it to achieve a flat-looking surface. In doing this, we start with the horizontal joints first. Step 4: Once the mortar is ready, we fill the joints with the new mortar. ![]() Step 3: Once the ground-out mortar joints are already clean, we mix the new mortar to make sure it matches the existing color of the brick. If the dust is too thick, we use a high-pressure air nozzle to do the job. ![]() Step 2: Using a masonry brush, we remove the dust and debris from the ground-out mortar joints. We usually use an angle grinder since it is less time-consuming than using a hammer and chisel. Step 1: When tuckpointing, the first step is to take out the existing mortar joints to a depth of about an inch.
