Best Practices for Concrete Finishing
Posted On 15 April 2023
Concrete finishing is a critical component of any construction project, as it not only affects the appearance of the finished product but also its durability and longevity. Achieving a high-quality finish on concrete surfaces requires a combination of skill, knowledge, and the right tools and techniques. In this article, we will explore the best practices for concrete finishing and how the New Zealand Master Concrete Placers Association (NZMCPA) supports its members in developing their finishing skills.
- Proper Planning
Proper planning is crucial for achieving a high-quality finish on concrete surfaces. This includes ensuring that the right tools and materials are on hand, that the area is properly prepared, and that the weather conditions are suitable for the finishing process. It’s important to consider factors such as temperature, humidity, and wind speed when planning concrete finishing.
- Proper Mixing and Placement
The mixing and placement of concrete are critical for achieving a high-quality finish. Concrete should be mixed according to the manufacturer’s instructions, and care should be taken to avoid over-mixing, which can lead to the separation of aggregates. When placing the concrete, it’s essential to avoid segregation and ensure that the surface is properly leveled and compacted.
Timing is critical when it comes to concrete finishing. The concrete should be allowed to set to the point where it can support the weight of the finisher but not to the point where it’s too hard to work with. This requires careful monitoring and adjustment of the timing, depending on the weather conditions and the specific concrete mix.
- Proper Tools and Techniques
The right tools and techniques are essential for achieving a high-quality finish on concrete surfaces. This includes using tools such as trowels, floats, and edgers, as well as techniques such as bull-floating, which helps to level the surface and remove any excess water. The use of proper tools and techniques can help to prevent the formation of cracks and other defects in the finished product.
- Finishing Patterns
The choice of finishing pattern can have a significant impact on the appearance of the finished product. A variety of finishing patterns are available, including smooth, broom, and exposed aggregate. The choice of finishing pattern should be based on factors such as the intended use of the surface, the aesthetic preferences of the client, and the environment in which the surface will be located.
The Role of the Master Concrete Placers Association
The NZMCPA plays a crucial role in supporting its members in developing their finishing skills. Through its training programs, certification processes, and ongoing support, the Master Concrete Placers Association helps its members maintain high standards in their work and stay up-to-date with the latest trends and techniques in concrete finishing. The association also provides a forum for members to share their knowledge and experience with one another, further enhancing their skills and abilities.
Benefits of Best Practices for Concrete Finishing
Adopting best practices for concrete finishing offers significant benefits for concrete placers and finishing companies. These include improved efficiency, reduced costs, and enhanced quality in the finished product. By using proper tools and techniques, concrete placers can achieve a more consistent and durable finish, reducing the risk of defects and other issues. Additionally, by staying up-to-date with the latest trends and techniques in concrete finishing, companies can position themselves as leaders in the industry, attracting clients who are seeking the highest standards in construction.
