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 it is important for you to know that masonry also has a weakness. So if ever you will find some extensive moisture damage or crumbling bricks, it is important for you to hire the service of professionals right away. But if the cement mixtures between the bricks are decaying, you need to do something about it. 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.
First, you should use some tools. You will need an angle grinder with a 4 to 4.5 inch diamond blade, as well as a rotary hammer drill that has a flat chisel head bit. 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. A joint raker or any other similar tool will also be needed in order to shape and smooth the wet paste. This will also require a bag of mortar that will be mixed inside a bucket.
In order to have a successful masonry repair, you need to know how bad the problem is. You can do this by using a house key and scratch it on the joints between the brick. If it will come out in chunks, you really need to replace it because solid mortar will not crumble. After gathering this information, it is important to use an angle grinder to create a horizontal cut below and above every joint. Once the bad sections will be removed, a hammer drill should be used to work through the grooves and chisel them out. In cleaning out the new grooves, a stiff paintbrush is highly suggested.
A new batch of mortar will be then mixed up once the bad mortar is removed. The bag of mortar should be mixed with water based on the instructions and the final consistency must be similar to a thick peanut butter. A glob of paste will be placed on top of the trowel and the trowel will be placed inside 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. Normally, a new masoned joint is ready to strike after about thirty minutes of new mortar application. So every time you will need a masonry repair, you need to make sure that you know the professionals to call.
