Top Ten Mistakes Made in Masonry Repair

Website design By BotEap.comWhen you have cracks sitting in your brick walls, you need to repair them. This process is known as aiming. However, before you try to repair it yourself or have repairs done by a contractor or handyman, you should know the ten most common mistakes made when grouting.

Website design By BotEap.comThe first mistake is to make the repairs before looking for additional problems. Repairing cracks in the mortar and brick before checking the foundation or other problems that occur can cause further damage to your home and to the masonry veneer.

Website design By BotEap.comSettlement cracks occur due to the settlement of the foundation and the application of stress to the bricks. This makes them a common symptom of foundation repair and can help understand where and how much movement has occurred in the foundation.

Website design By BotEap.comPlacing mortar and replacing broken brick along these settling cracks limits the ability to accurately repair the home’s foundation. Performing these repairs often results in damage to the brick walls when the foundation is being repaired. Any mortar or brick placed in these cracks to fill the space becomes a wedge and forces the opposite crack to form in the area and the brick tends to push out at the corners of the house causing the walls brick from cracking, leaning away from the house, or coming off the foundation completely when the house is erected.

Website design By BotEap.comThe second most common mistake made when repairing settling cracks in brick is choosing a foundation repair company to level the foundation. There is a difference between leveling the foundation of your house and fixing foundation problems.

Website design By BotEap.comTo my knowledge, a perfectly level foundation for a house has never been built, and leveling the foundation under your house would apply stresses to your home and cause more problems with your foundation. This, in turn, would create more cracks in the bricks and mortar joints around your house. When they emphasize word level and use a computerized level for their readings, it is a strong indication that they intend to try to level their base even if it causes more trouble. If they focus on lifting, stabilizing, adjusting, and using the cracks in the mortar and brick to acquire their range of motion in the house slab, they are likely to get more accurate details about the movement and have a better chance of providing a better understanding of the movement. quality basis. repair services

Website design By BotEap.comThe third common brick repair mistake is using these mortar repair caulking tubes in an attempt to repair cracks yourself. Although caulking is used around doors and windows and in expansion control joints to seal the wall and allow for movement, it is not designed to be used as a mortar and may cause other damage to the brick.

Website design By BotEap.comCaulking will never look like mortar and tends to be difficult to clean from brick faces due to its texture. The same goes for many other masonry repair products. They contain adhesives, epoxy, and other admixtures that can be difficult to work with and remove. Often requires removal of all brick in areas where these products are used to repair brick. If you wish to repair cracks in the mortar yourself, you must use a suitable grouting mortar with the same composition as the original. These are not bulk items, they are custom made to match your mortar composition and require mortar match analysis of your existing mortar samples.

Website design By BotEap.comThe fourth masonry repair mistake is how to match the mortar. This should not be confused with the color of the mortar. Mortar matching is the process of analyzing samples of the mortar to identify its composition, performance and formula. Since the color of the sand and other materials in the composition affect the color, they are related, but the base formula of a mortar composition must be matched before attempting to match the color of an existing mortar.

Website design By BotEap.comThe composition and formula of the mortar are the guide to make a suitable repair mortar and maintain the formula. This is important because if the mortar does not match and has a different composition than the original mortar, it can have complications that make the color more difficult to match, cause damage to the bricks, prevent the new mortar from adhering to the old mortar, and could allow the wall to collapse if the mortar crumbles.

Website design By BotEap.comThe fifth most common mistake when repairing masonry is matching the color of the mortar. Most of the time the analysis of the composition of the original mortar is omitted and general assumptions are made instead. This causes difficulty in matching mortar color because color is a direct result of the composition and ratio of materials in the mortar mix. To match the color of a mortar, you must first match the formula and composition of the existing mortar.

Website design By BotEap.comOnce you have the base formula and composition, you can adjust the color of the mortar by adjusting the colors of the base materials and adding pigments as needed. However, a common mistake is adding pigments or other materials too quickly or changing the base of the formula. You must stick to the base formula to maintain the yield and type of mortar being produced, and remember to add all portions slowly as you can continue to add but cannot take anything back.

Website design By BotEap.comIn masonry repair, the sixth common mistake is the depth of the repairs. A patch or bandage covers the top of a problem, but to repair cracks, you need to remove some of the existing mortar. It must be removed to a depth that allows a good bond of the new mortar with the old mortar and bricks. This will help ensure a durable masonry repair. Generally, a good depth is about 1/2-3/4 inch in mortar joints. More is better, especially when space allows you to replace the entire mortar joint.

Website design By BotEap.comThe seventh item where errors occur is in the preparation of the cracks for grouting. Dust and debris left in cracks prevent new mortar from bonding to old cement and prevent mortar joints from filling completely. It is important to brush off any loose debris or dust and to rinse and dampen the old mortar. This will help the new mortar adhere to the existing mortar.

Website design By BotEap.comThe eighth mistake that is commonly made is when mixing the mortar. Too often the water is added quickly and exceeds the amount needed and attempts are made to adjust this. The most common attempt to correct this problem is to add sand or mortar to the mortar. When you do this, the composition formula changes and the resulting mortar will not meet your requirements.

Website design By BotEap.comIf you add too much water, you need to add more of all the compounding materials according to the formula to adjust this without changing the ratio and type of mortar. It’s best to add water or pigments slowly, as they can’t be removed, and when mistakes like this happen, you’d better throw out the mortar and start over.

The ninth most common mistake when aiming with creases is filing the mortar joint completely. When filing mortar joints they may look full, but they should pack firmly into the mortar joints. Dust and debris can prevent this and should be cleaned before installing new mortar.

Website design By BotEap.comWhen mortar joints are not filled completely, they tend to crumble when pressure is applied. This is often noticed during the machining of mortar joints if the mortar has started to harden in the wall before the joints or machining is done. If this is noticed, remove the mortar where it occurs and replace it. Also, remember that starting to harden does not mean letting it harden before working the joints. If you apply pressure to dry mortar that has not cured, the mortar will crack or crumble and will need to be replaced again.

As I mentioned earlier, dressing should be done when the mortar begins to harden, but before it becomes too hard to dress. However, when working the mortar, it is important that it matches the type of existing tools. There are all different designs for the tools that shape mortar joints. The most common design is a rounded or sloped mortar joint. You will want to use a joint tool that will produce the correct design and size of mortar joint. These tools come in wider angles for thicker mortar joints.

Website design By BotEap.comThis is important so the repairs blend in with the wall. Using a mismatched jointer will cause the mortar to cast a shadow at the intersections of the new and old mortar. This also happens with mortar labels or excess mortar that is pressed down with screeding tools. You must brush off the excess and blend the edges of each and every mortar joint for the repairs to match properly.
