When cracks are sinking in your brick wall, you need to rebuild them. This process is known as tack pointing. But before you try to fix this yourself, or before hiring a repair done by a contractor or handyman, you should be aware of the top 10 common mistakes when repelling mortar.
The first mistake is to do a repair before checking for additional problems. Repairing mortar and brick cracks before checking whether foundation or other problems are occurring can cause damage to houses and masonry premises greatly.
Crack settling by arranging the foundation and applying stress to the brick. This makes it a common symptom of basic restoration, and it helps to understand where and how much movement occurred in the foundation.
Locating the mortar along these sedimentary cracks and replacing broken bricks limits the ability to correctly repair the housing foundation. Performing these repairs will often damage the brick walls when the foundation is repaired. Mortars and bricks arranged to fill gaps in these cracks become wedges, cracks on the opposite side are formed in the area, the bricks are pushed out to the corners of the house, causing cracks in the walls of the bricks Or tilt from home. When the house is lifted it completely leaves the foundation.
Before repairing the mortar's cracks, you can not feel enough stress to check the housing structure or other problems related to the foundation.
Brick sedimentation The second most common mistake in repairing cracks is to pick the foundation repair company that repairs the foundation. There is a difference in flattening the foundation of your home and solving the basic problem.
There has never been a family foundation built at the perfect level you know. Flattening the foundation of your house puts pressure on your house, which in turn creates many cracks in the bricks and mortar joints around your home. When they emphasize the level of a word and use computerized levels for its reading, it is a strong will to try to level your foundation even causing more problems. If they emphasize lifting, stabilizing, adjusting, and using the cracks of mortar and bricks, focusing on acquiring the range of movement of the residential slabs, they can grasp the details of the movement more precisely and provide a high quality foundation The more likely you will offer the repair service.
The third common mistake of repairing bricks uses these tubes of mortar repair calling trying to repair their own cracks. Crimping is used to seal the wall around doors and windows and expanded control joints but allows movement but is not intended for use as a mortar and can damage other bricks There is sex.
Caulking is never seen like a mortar and it tends to clean the surface of the brick due to the texture of the brick. The same applies to many other masonry repair products. They include adhesives, epoxies, and other additive mixtures, which are difficult to use and difficult to remove. In many cases, you need to remove all bricks in the area where these products are used to repair bricks. If you want to repair mortar cracks yourself, you need to use the appropriate repointing mortar with the same composition as the original one. These are not bulk goods customized to match your mortar composition but mortar matching analysis of existing mortar samples is required.
The fourth stone repair mistake is how you match mortar. Do not confuse this with matching mortar color. Mortar matching is the process of analyzing mortar samples to identify composition, performance and formulation. Since the colors of sand and other materials in the composition affect color, they are related, but the basic formulation of the mortar composition must be adapted before attempting to match the color of the existing mortar .
Mortar compositions and formulations are guides for making suitable repair mortar and maintaining the formulation. This is important, as mortar is a mismatch and composition is different from the original mortar, it makes it harder to match colors, damages the bricks and prevents new mortar from combining with old mortar. If the mortar collapses the wall may fall.
The fifth common mistake in repairing masonry is to match the color of the mortar. In most cases, mortar composition analysis of the original mortar will be skipped, instead a general premise will be made. This makes it difficult to match the color of the mortar, since the color is the direct result of the composition and the ratio of the material in the mortar mixture. In order to match the color of mortar, it is necessary first to match the formulation and composition of existing mortar.
After the basic formulation and blending, you can adjust the color of the base material and adjust the color of the mortar by adding pigments as needed. However, a common error is adding pigments and other materials too quickly, or changing the formula base. You must comply with the basic formula to maintain the performance and type of mortar being produced. You can continue adding, but you can not regain anything, so please add all parts slowly.
In masons repair, the sixth common mistake is the depth of repair. Patches and bandages cover the top of the problem, but in order to repair the cracks, it is necessary to remove some of the existing mortar. It must be removed to a depth that allows for a good bond between the new mortar and old mortar and brick. This will help to ensure the repair of masons. In general, a good depth is on the order of 1/2 to 3/4 inches deep of the mortar joint. Especially when the clearance can replace the entire mortar joint, it is better.
The seventh item where the error occurs is to prepare the crack for re-arcing. Dust and debris remaining in the crack prevent the new mortar from binding to the old cement and prevent the mortar joint from being completely filled. It is important to peel off loose debris and dust, rinse off old mortar. This will help new mortar bonds to existing mortar.
The eighth mistake is to mix the mortar in general. Water is added quickly, exceeding the necessary amount, trying to adjust this. The most common attempt to solve this problem is to add sand or mix to the mortar. Doing this will change the composition formula and the resulting mortar will not meet your requirements.
If too much water is added, it is necessary to further add the whole composition based on the formula in order to adjust without changing the proportion and type of mortar. It is best to slowly add water or pigment as you can not remove water or pigment. If there is such a mistake, it may be better to start over after disposing mortar.
The tenth most erroneous error in tack pointing is to completely fillet the mortar joint. When painting the mortar joints they may look perfect, but they must be tightly packed in the mortar joint. Dust and debris can prevent this and need to be cleaned before installing a new mortar.
If the mortar joint is not completely filled, it tends to collapse when pressure is applied. This is often noticed during touring of mortar joints when the mortar becomes hard on the wall before joining or tooling is done. If you notice this, please remove the mortar that occurred and replace it again. Also, hardening does not mean that the joints become hard before tooling. If pressure is applied to drying the uncured mortar, cracking and crushing of the mortar will occur and it will need to be replaced again.
And the tenth most common mistake of brick mortar restoration is touring and brushing of mortar joints. As I mentioned earlier, before the mortar starts to harden, it is necessary to install the mold before the mold becomes hard. However, when touring a mortar, it is important to match with existing touring type. Tools that shape mortar joints all have different designs. The most common design is a rounded or raked mortar joint. We recommend using a joint tool to generate the correct design and size of the mortar joint. These tools appear at wider angles to thicker mortar joints.
This is important to make repair into the wall. Using unmatched joints, mortar will cast a shadow at the intersection of old and new mortar. This also happens with mortar tags extruded with cracking tools or excess mortar. You need to polish the extra stuff and blend the edges of each mortar joint so that the repair is properly matched.
As you can see, masonry repair is a very detailed process, with minor differences in details greatly changing the result of repair.
