Bricklayers Perth is a skilled tradesperson who constructs, repairs and maintains walls, houses, and other structures. They work with clay bricks, concrete blocks, and mortar.
Some duties include interpreting work orders, measuring working areas, and using a trowel to lay bricks and mortar. They also may need to lift heavy materials and erect scaffolding.
Bricks are strong, classic, and timeless, making them an excellent building material for various structures. But bricklaying is a skill that requires careful attention and planning to achieve a professional finish. Bricklayers must also have high stamina and strength to perform productive work through long shifts and handle weather conditions.
To begin, bricklayers must prepare the site by clearing and cleaning it. They then need to lay a mortar bed on the ground, slightly thinner than the individual bricks. This mix of concrete and sand should be spread out using a trowel until it is evenly coated.
Once this base has dried, the first course of bricks can be laid. This should be done along a level line, ensuring the bricks you lay align. A pin can set this level line by inserting it into the mortar at one end of the wall and stretching it out. This should be done to each of the ends of the wall, and then once the line has been set, it can be lifted and moved up or down with each new course.
Each brick is then placed on the mortar, using a bolster chisel and lump hammer to ensure they are positioned correctly. Once the brick has been pressed down, it needs to be struck and brushed with a “jointer,” a tool that is a piece of tubing of the same size as your joint spacing bent into an “S” shape. This is rubbed across the mortar joints to smooth them out and create a neater finish.
As each course is laid, the bricklayer must keep the line straight by checking it with a spirit level, tapping each brick if necessary. As a guide, the first brick of each course should be laid with a half brick at either end to avoid the vertical joints lining up and weakening the structure. Each course should follow this technique until the whole wall is complete.
The mortar used by bricklayers must have the right consistency to keep the layers of bricks together and withstand the structure’s weight. It also must contain the correct amount of moisture to prevent it from being too thick and unworkable during construction sessions.
Mortar can be bought in a dry, pre-mixed form that is combined with water, or it may be mixed on-site. A mixer is useful for creating the ideal mixture but can be expensive to purchase and maintain. The most common ingredients are lime, cement, and sand. However, various additives are available for the mason to include in his mix. These additives can help make the mortar more durable, improve its ability to bond with other materials and increase its overall strength.
Whether mixing your mortar or purchasing pre-mixed, it’s important to follow the instructions on the bag to ensure that the ratio of water to dry material is correct. Most mortar mixes require around 6 quarts of water per 50lb bag. The ingredients should be stirred with a hand or power mixer until the mixture reaches a workable consistency. Once the mortar is mixed, it should hold its shape if you dip a trowel into it and pull it upward.
Once the mortar has been mixed, it should be allowed to rest. This allows the ingredients to rehydrate and bind together. It’s possible to speed up this process by adding a small amount of water. However, this is not recommended as it can cause the mortar to become too wet and difficult to work with.
A bricklayer should test the consistency of his mortar before he uses it. This can be done using a trowel or gloved hand to scoop up a small portion of the mixture. The mortar is ready to use when it holds its shape and does not slide off the trowel or crumble easily.
Some bricklayers prefer to mix their mortar to ensure that the ratio of ingredients is correct and that they can control the quality of the finished product. While this task is time-consuming, producing quality brickwork is often worthwhile.
When laying the first course of bricks, keeping a level and tape measure with you is a good idea. This will help you keep the wall straight as you go. After each brick is set, check it with the level and ensure the mortar underneath and on top of each brick is even. Continue to add bricks to your wall, taking care to butter the ends of each brick and gently press it into place with the trowel handle until it is firmly bedded into the mortar. Once the first course is laid, lift the guideline for the next row and repeat the process.
Unlike modern smooth bricks, face bricks are wire-cut and have a textured surface. They are also made of a mix of clays with different characteristics. Some are fired at lower temperatures to make them stronger, while others are fired at higher temperatures to give the brick a lighter texture and better color. There are also many different sizes and colors of face bricks available.
Masons use various materials to build buildings, including bricks and concrete blocks. A mason’s job involves many tasks, from laying bricks and pre-cutting stones to mixing mortar and preparing the building site. Many masons start as bricklayers, where they learn the fundamental skills of masonry work.
The craft of bricklaying is complex and requires years of study and apprenticeship to master. More masons need to receive adequate training and knowledge of traditional bricklaying techniques. Inadequate training has resulted in the use of modern bricklaying materials, such as ordinary Portland cement (OPC), which is inappropriate for traditional brickwork and can lead to the deterioration of the bricks themselves.
In addition to the basic skills needed for bricklaying, masons must understand and be able to interpret the nuances of their material. They must know the characteristics of various clays and their varying physical properties, such as absorption, weight, density, chemistry, and chemical composition. They must be able to evaluate and select the appropriate brick for each project based on several factors, such as texture, color, size, and surface finish.
A bricklayer’s work can leave dust and debris, especially when the project involves exterior walls. It’s important to clean up properly so the brick stays intact and doesn’t develop cracks or other problems.
The first step is wetting the brick with a garden hose before applying any cleaning solvents. This will help prevent water damage if the brick is left dry and exposed to the elements.
Once the brick is wet, a basic soap solution or vinegar can clean off dirt and other substances. This is an effective way to remove basic stains from the surface of the brick and can be done regularly to keep your property looking its best.
More difficult stains, such as mold and mildew, may require more serious cleaners. A bleach mixture can be effective for this purpose, as it will dissolve and wash away these substances without damaging the brick.
Muriatic acid is also an effective cleaner for brick, but it is important to follow safety precautions when using this substance. This chemical can be dangerous to touch and should only be used in a well-ventilated area where the fumes can’t reach other surfaces, such as wood or metal.
You can use a commercial brick-and-mortar detergent for stains that are particularly stuck on, such as grease or grass stains around your home’s foundation. This product can be sprayed onto the brick and scrubbed with a brush to loosen and remove stubborn materials.
You can use a commercial masonry cleaner with hydrochloric acid for more severe stains, such as vanadium staining from rusting metal fixtures in your home. This powerful substance can be dangerous, so you should always wear gloves and goggles when applying it to brick and ensure it is not in contact with other surfaces that could react negatively to the acid. You should also test the solution on a small area of your brick before proceeding with the entire application.
