Concrete Finisher
Concrete finisher; It is one of the very important construction equipment used for laying areas such as highways, roads and airfields. Another known name is asphalt paving machine. It is generally used in concrete and asphalt casting. It can be used not only for surfaces such as roads, but also in many construction sites where asphalt and concrete are used.
The paver ensures that the newly poured concrete or asphalt is flat and homogeneous. It is one of the construction tools used for smooth appearance. It is preferred in large scale projects. There are different models depending on the usage area. Among the most important models are offset type slipform and slipform track pavers.
Concrete Finisher Models
Offset slipform: The offset slipform concrete finisher carries the concrete into the formwork with a loading belt. On the other hand, there are models that carry the concrete to the sliding mold over the feeding helix. The offset piece on the paver can be mounted on the left or right side of the implement. The mold to be used in the device can be in different sizes and shapes depending on the purpose of use. It is produced from offset profile casting.
Slipform molded between pallets: In this type of paver models, concrete is placed in front of the equipment. Concrete pouring is done by spreading auger or plow. The shaking section in the machine thickens the concrete. The mold shapes the concrete. The super trowel ensures that the surface becomes smooth. Concrete laying is carried out in two layers.
Curing: After the concrete is laid, the curing machine provides the requested surface structure. As the dispersion sprays while shaping, the concrete is prevented from drying out immediately. Brush or artificial grass is generally used for the desired surface shape.
Side feeding: From time to time, reinforcement is needed while concrete is being laid. The concrete paver used at this stage is a side feeding device. The side feed moves from the front of the molded paver.
Concrete Finishing Equipments
Concrete finishing equipment is the equipment used to make the surface smooth after the concrete is laid. Different tools can be used to make the surface textured or smooth. These equipment can be different from small projects to large projects.
Hand-held trowel blades are generally used in small-scale plastering works. It is produced from wood, plastic or steel. It is preferred to obtain a polished surface on concrete. Electric trowels are also used for finishing the concrete. Vibrating concrete levelers also provide leveling of concrete by vibration. It is generally used in pavement works. In large-scale projects, concrete finisher machines are used. Such machines are preferred in road and airfield constructions.
Concrete Finisher Advantages
The concrete finisher used in large-scale construction projects provides high efficiency. It helps to smooth and compact asphalt or concrete (material used). Thanks to automation technology, it needs less human power. It reduces the curvatures on the concrete floor.
Workers make less effort while laying concrete. Time saving is achieved as the concrete laying process will take a shorter time. The project is completed in less time. Thanks to its mechanical technology, less harm is done to the environment. Although the investment is costly, it allows the entrepreneur to save labor and time in the long run.
Are you intrigued by the idea of transforming raw concrete into beautifully finished surfaces? Do you have a passion for precision and craftsmanship? If so, a career as a concrete finisher might be the perfect fit for you. In this guide, we’ll delve into the world of concrete finishing, exploring everything from the essential skills required to succeed in this field to the various techniques used to achieve flawless results.
What Does a Concrete Finisher Do?
Concrete finishers are responsible for the final aesthetic and functional touches applied to freshly poured concrete surfaces. Their primary duties include:
Smoothing and Leveling: Concrete finishers use specialized tools such as trowels and floats to smooth and level freshly poured concrete, ensuring a uniform surface free of imperfections.
Texturing and Coloring: Depending on the desired finish, concrete finishers may apply textures or colors to enhance the appearance of the concrete surface. This can involve techniques such as stamping, staining, or etching.
Sealing and Protecting: To prolong the lifespan of the concrete and enhance its durability, finishers often apply sealants or coatings that protect against moisture, stains, and abrasion.
Essential Skills for Success
Becoming a skilled concrete finisher requires a combination of technical expertise, physical stamina, and attention to detail. Here are some essential skills you’ll need to master:
Knowledge of Concrete Properties: Understanding how concrete behaves and cures is crucial for achieving optimal results. This includes knowing how factors such as temperature, humidity, and aggregate content can affect the final outcome.
Proficiency with Tools and Equipment: From hand tools like trowels and edgers to power tools like concrete saws and grinders, concrete finishers must be adept at using a variety of equipment safely and effectively.
Attention to Detail: Precision is key in concrete finishing, as even minor flaws can detract from the overall appearance of the surface. Finishing professionals must have a keen eye for detail and the patience to ensure every aspect of the job is executed flawlessly.
Physical Fitness: Concrete finishing is a physically demanding job that often requires lifting heavy materials, bending, kneeling, and standing for extended periods. A good level of physical fitness is essential to withstand the rigors of the work.
Mastering Concrete Finishing Techniques
The art of concrete finishing encompasses a wide range of techniques, each suited to different applications and desired aesthetics. Some common techniques include:
Broom Finish: This simple yet effective technique involves dragging a broom across the surface of freshly poured concrete to create a textured finish that improves traction and reduces slipperiness.
Stamped Concrete: Stamping involves pressing molds or stamps into the surface of the concrete to create patterns that mimic the look of brick, stone, or other materials. Stamped concrete can add visual interest and elegance to outdoor spaces like patios and walkways.
Exposed Aggregate: By removing the top layer of concrete to reveal the underlying aggregate, finishers can create a textured, decorative finish that adds dimension and visual appeal to driveways, sidewalks, and other surfaces.
Polished Concrete: Polishing involves grinding and buffing the surface of the concrete to achieve a smooth, glossy finish that resembles natural stone. Polished concrete is highly durable and low-maintenance, making it a popular choice for commercial and industrial settings.
As a concrete finisher, you have the opportunity to transform ordinary concrete into extraordinary works of art. By mastering essential skills, staying up-to-date on industry trends and techniques, and honing your craft through practice and experience, you can build a rewarding career in this dynamic field. Whether you’re creating decorative residential patios or functional commercial floors, the possibilities are endless when you’re a master of concrete finishing.
