What Is Masonry Repair
The strongest and most durable construction material for a long time has been the brick. As a matter of fact, there are actually a lot of buildings made of bricks that are still standing today. But you need to know that there is also a weakness when it comes to masonry. That is why it is important for you to call a professional right away after you will discover some great moisture damage and crumbling bricks. And you should always do something right away if you will see that the mortar joints are decaying. This article will provide you with a guide on how you should be replacing the bad mortar joints in order to prolong and preserve the structural integrity of your brick building.
You will need some important tools. The power tools that you will need are the rotary hammer drill that comes with a flat chisel head bit and an angle grinder with a 4 to 4.5 inch diamond blade. You should also make use of a tuck pointer and a trowel, and a flat blade that will pressure the new mortar to the joints. It is also important to have a joint raker or some other similar tool for the shaping and smoothing of the wet paste in order to complete the repair. This will also require a bag of mortar that will be mixed inside a bucket.
Knowing how bad the problem is important for a successful masonry repair. A house key can be used to scratch the joints in the middle of the brick. You need to know that solid mortar does not crumble so if it will come out in chunks, then you really need to have it replaced. A horizontal cut should be made using an angle grinder below and above each of the joints once all of the necessary information are gathered. Once the bad sections will be removed, a hammer drill should be used to work through the grooves and chisel them out. The new grooves can be cleaned out using a stiff paintbrush.
Once the bad mortar is removed, a new batch of mortar should be mixed up. The mortar will be mixed with water depending on the instructions on the bag and the final consistency of the mortar must be similar to a thick peanut butter. A glob of paste must be placed on top of the trowel and the trowel should be placed in the empty groove. The tuck pointer will be used to tightly pack the fresh mortar between the bricks. It is also important to make sure that the paste will not harden once the grooves are filled in with the new mortar. A new masoned joint usually is ready to strike after thirty minutes of application. That is why it is important for you to always ask for help from a professional when doing a masonry repair.
