What you need to know about brick tuckpointing
Masonry tuckpointing is very important as it helps keep the buildings steady. As you might already know there are different materials that are used in masonry. The most common ones are brick and stone. Those that have tried to tuckpoint brick usually find it much easier than tuckpointing stone. This could be attributed to the fact that bricks are usually easy to align and so the filling of the spaces with mortar is also simpler as compared to that of stones. There are a few differences in tuckpointing stone walls and tuckpointing brick walls. Some of these differences are discussed below.
Stone tuckpointing and lime
In most of the brick tuckpointing jobs, the contractors use lime mortar to get the desired effects. However, when it comes to stone, lime mortar should not be the first choice. This is due to the fact that this type of mortar tends to take a much longer period of time to dry as compared to the Portland cement. The stone walls have larger spaces than the brick walls and so you will need mortar that can dry up quickly.
Cleaning of the spaces
It is also very important that the spaces between the stones are well cleaned before the filling. This is important not only to remove the debris but it also dampens the walls. Dampening the walls is very important due to the fact that it will ensure that the old stones do not suck up all the moisture from the wet mortar. The cleaning of the wall is essential in any kind of tuckpointing including that that involves bricks.
After the spaces are clean one has to fill them with the mortar. Ensure that the mixture you have is the right consistency so that it can hold the wall together. Mortar for the stone walls is a bit thicker than that of the brick walls. Failure to do this will result in the collapsing of the wall all together. Ensure that the spaces are well filled before you flatten them out. In brick tuckpointing, this is the same case. However, you might have noticed that brick tuckpointing does not require as much mortar as that which is required for the stone foundations.
It is also quite important to keep on wetting the wall until the mortar dries up substantially. You might already know that in brick tuckpointing, you have to wet the bricks until they are dripping wet and that is it. However, when tuckpointing stone, you will have to wet the wall more than once in order to avoid the wall from sucking up all the moisture in the mortar. The stone walls do not hold any water and so one has to keep on spraying water on the wall.
There are so many things that are different when you compare tuckpointing brick and tuckpointing stone. One thing that remains constant is that if the wall or joints are badly damaged then it is best to leave the work to the tuckpointing contractors. These are professionals who will help you in whichever way that you want to make your walls secure.
