Types Of Mortar For Tuckpointing and Repointing

What is mortar and exactly what different types of mortar are there. Mortar, as we know it today is a combination of 3 elements the element is a Portland based cement, the second is fine masonry sand, and the last element is clean water. Mortar is manufactured in different strengths for different uses their strengths are rated by various letters dictating their cured PSI. The system in rating mortar is based on the words MaSoN wOrK which every other word is used. M stands for type M cement which is rated at 2500 PSI, S stands for type S cement, N stands for type N cement and so on. Type S cement at 28 days is rated at 1800 PSI when it is completely cured and hydrated. Most tuck pointing jobs involved using or type K cement type O cement. At 28 days type cement K is rated at 350 PSI. The reason behind using hydrated lime to create a lower PSI for cement used in tuck pointing is the older brick used in buildings was much softer than current brick standards. The more Portland cement used in mortar makes the blend stronger, but in turn if you’re working with historical brick tuck pointing projects. It’s important not to use too strong of a mortar.If too strong of a mortar mix is used in your re pointing project it can lead to the destruction of the original brick on your commercial or residential buildings façade. Whenthe mortar has a high compressive strength it will make the brick face spalled off with no real hope of recovering from the damage. Mortar that is used in repointing brick should be equal to or lesser than that compressive strength or less than the original mortar used in the construction and laying of the brick. For example lime is the key, because before there was Portland cement, lime and sand was used to lay brick. Older brick is much softer than brick being manufactured today, so it’s important to use a mortar blend that has a lower PSI rating when tuck pointing older buildings. Typically, Fairfax contractor uses type N for newer residential tuck pointing jobs on homes built after the 1930s. But if your residential or commercial building is older than great consideration needs to be taken when choosing what type of mortar is to be used to re-point the brick façade of the building. These considerations consider the type of lime to Portland ratio and color of the mortar that will be used to replace the old worn joints.

Why Is Repointing Brick So Expensive

The reason that repointing brick in your home our your commercial building is so expensive is because it takes an artisan to replicate the color, the joint and the type of mortar that was originally or historically used in the façade of your home or commercial building. The second reason is tuckpointing is very labor intensive. The first step is to determine how your home or building will be scaffold so that the Masons can cut and repoint all the joints in the brick. If more than 50% of the brick in your building a home need to be reported, it’s probably wise to re-point the entire structure. Any contractor that operates in Virginia must first hold a contractor’s license issued by the DPOR and Fairfax Contractor holds a class A RBC Residential Building Contractor (CBC) Commercial Building Contractor license#2705154312 expiration date July 31, 2018. In addition, we have both Workmen’s Compensation insurance, and complete general liability insurance that is up-to-date. Many commercial buildings will need to take into consideration the fact that the sidewalk may be closed or partially closed during the repointing of the façade of the building. These permits are not only time-consuming to procure but also are expensive. Taking into consideration that restoring a brick façade on a home or at building requires the utmost skill and artistry of a competent team of masons will tell you that this project is not going to be inexpensive.

Color Matching Mortar For Tuckpointing

Once we have scaffold your project OSHA standards, we will start cutting out all the old mortar joints. Typically, if 30% to 40% of the wall needs to be re-pointed it probably makes sense to do the entire wall. To re-point. Brick work and in need to get at least a 70% embedment into the old brick by removing that bad mortar or lime and sand mix depending on the age of the building. Working in small areas, because you don’t want to get ahead in yourself, the mortar is carefully removed by the use of an angle grinder with a diamond wheel. What separates a semi pro to a artisan Masons intact pointing is matching up the old mortar to a T. This is critical for a number of reasons. One of the building may lie within a historic district and the historical department in your particular city or county may require that the exact match of mortar is used in the repointing project. Often times it’s wise to use a premixed blend of Portland line that’s been pre-colored, such as Essrock Brixment this bag blend is very convenient because of the consistency it offers when tuck pointing large brick areas. Often times a good Mason will have to hand mix a number of different batches to create a color that is very close to the original mortar color used when building our home was built. This is difficult because the mortar has now become aged and more of the sand has been exposed through acid rain is truly takes some artistic skills and a great eye for color.
