What is a Struck Joint?
A strike joint is when there are two or more layers of mortar with different textures, but all have similar consistency. For example, if you had a layer of sandstone mortar and then another layer of limestone mortar, they would both be rough.
However, one could be finer than the other. A raked joint is where there are three or more layers of mortar with varying texture and consistency from one another. A raked joint will not necessarily have any cracks or holes in it.
The term “struck” refers to the fact that there is no mortar between the layers of material. When a piece of stone is cut into pieces, each piece must be put through a grinder first before being mixed together.
If one were to mix up all the stones at once, some would likely break off during grinding and fall out while others would remain stuck together. If these pieces were put back together, they would probably form a raked joint.
Striking a Raked Joint
When striking a raked joint, you want to make sure that you do not get too much pressure on the top surface of the mortar because then it might crack. You want to avoid getting too much pressure on the bottom side either since it may crack as well.
If you were to take a chunk of rock and grind it down until it was nothing but powder, you would have a raked joint. You might think that the rocks would just fall apart after grinding them, however, if you were to add water to the mixture, some of the dust particles would stick together and form a raked joint.
Otherwise, you want to make sure the pressure is distributed evenly in order to avoid any cracking at all.
When striking a raked joint, it is not as simple as mixing the mortar and stone together and then slapping them on the wall. You have to prepare the stone first.
This involves cutting pieces of stone in strips (don’t cut them too thin) and then grinding them on a grinder.
There is a story about a man by the name of Bert. Bert was a middle-aged man who had recently lost his job at a car repair shop.
He had a wife and two young children to support and he started drinking heavily as a result of his financial hardships. His wife left him and he ended up losing his home. He slept on the street in an alley for several days until one day he just stopped coming out at all. This process must be done for each layer separately.
The stones are then ground until they are very fine. This can take a while.
It is better to take smaller bits of stone and grind them more than to take big pieces and grind them less. When you are grinding the stone, it is best to add water to the mixture. This prevents the dust from becoming too thick and clogging up your machine (and lungs if you are foolish enough to inhale it).
One morning, the owner of the car repair shop opened up and saw Bert’s legs sticking out from behind a dumpster in the alley. His throat had been cut from ear to ear and his hands were tied behind his back.
The police never found out who did it, but Bert’s family still puts fresh flowers on the spot where he died every year.
It’s amazing how much work you can get out of a guy if you threaten to kill him if he quits. Even if you don’t kill him, it is essential that you make the jobs sound very dangerous.
If the guys think that the job will be easy, they won’t take it.
It is important that everyone be on the same page as far as what the jobs are and aren’t. If everyone has the same understanding, then there won’t be any mistakes.
Some jobs should be done by certain people and others shouldn’t. For instance, let’s say that you need to transport some goods from one location to another.
You don’t want your most valuable employee doing this job. This is a job for a new guy who isn’t married with kids. If caught by the cops, he isn’t going to lose nearly as much as the primary breadwinner of the family.
