Key Steps in the Combined Finishing Process

In the combined finishing process of concrete, it is essential to ensure that bleed water has completely evaporated before commencing any finishing techniques. This step is crucial for maintaining the integrity of the surface.

Following this, a broom finish can be applied to enhance the surface texture, which is particularly beneficial for flooring and pool areas.

Once the broom finish is complete, a steel trowel should be utilized to refine the concrete surface. This can be done either manually or with a mechanical trowel, with an emphasis on identifying and addressing any surface imperfections that may arise.

During this phase, it is important to float the floor gently, ensuring that the air content within the concrete mix remains below 3% to prevent aeration-related issues.

Documentation of each phase of the finishing process should be meticulously maintained. This includes logging dates and contractor information while considering privacy concerns.

Moreover, it is advisable to perform a thread test to check for delamination, which can indicate potential problems with the concrete surface.

In surface documentation, the use of Inc., V, and D designations is recommended for clarity and consistency in recording and referencing the finishing process.

Selecting Concrete Mixes for Optimal Surface Performance

Selecting the appropriate concrete mix is crucial for achieving optimal surface performance in combined broom and trowel finishes. For new flooring or pool projects, it is advisable to use air-entrained concrete with an air content of less than 3%.

The choice of finishing method can significantly impact the final quality of the surface. Machine finishing techniques, such as utilizing a steel trowel or float, can trap moisture within the concrete, which may lead to delamination. Therefore, hand finishing is recommended as it helps preserve surface integrity and allows for the evaporation of bleed water before finishing operations commence.

Incorporating a broom finish can assist in enhancing surface characteristics by improving texture and reducing potential air entrainment concerns.

It is also essential for contractors to maintain thorough documentation throughout the process. Logging dates and monitoring every aspect of the project will help ensure adherence to specified requirements, including those related to privacy and compliance standards. This structured approach can mitigate risks and enhance the performance of the concrete surface.

Choosing the Right Brooms and Tools for Finishing

Selecting appropriate finishing tools is essential for ensuring the quality and durability of a concrete surface created using a broom and trowel technique. To begin, a 24" aluminum broom is recommended for general-purpose concrete finishing, particularly on surfaces such as flooring and pool decks. This choice offers a balance of durability and performance.

For smaller areas, a more compact 18" wood broom is available at a reasonable price of $16.70. Its size makes it suitable for detailed work in confined spaces. Alternatively, contractors seeking a smoother finish may benefit from a 24" Green Nylex® soft broom, which is designed to enhance surface appearance while providing privacy.

In addition to brooms, consideration should be given to steel trowels or machine floats, which can be used for hand or mechanical finishing of floors. Each tool offers distinct advantages depending on the application and the desired finish quality.

Finally, it is prudent to maintain a record of when threads or replacement strips—such as those provided by V Inc—are installed. This practice helps ensure consistent surface performance over time, contributing to the overall longevity of the concrete surface.

Addressing Air Entrainment and Its Impact on Finishing

Air entrainment plays a significant role in the concrete finishing process, and understanding its effects is essential for attaining a durable and reliable surface.

When utilizing new air-entrained concrete for flooring applications, it is important to note that finishing techniques, such as steel troweling or machine finishing, may lead to delamination if the air content exceeds three percent.

In such cases, it is advisable to employ a broom or hand float method during finishing. This technique allows for the exposure of the surface, facilitating moisture escape and thus reducing the likelihood of separation. This guidance is corroborated by industry practices and documented experiences from contractors, including Flooring Inc.

Additionally, after completing the finishing process, it is recommended to conduct a thorough inspection for any signs of bubbling or delamination.

Keeping an accurate log of the date and threading can be beneficial in monitoring potential issues related to pool or privacy surfaces in the future. Such diligence helps ensure the integrity and longevity of the finished concrete surface.

Best Practices for Exterior vs. Interior Applications

When working with concrete, the finishing technique employed is significantly influenced by whether the application is intended for exterior or interior use. For new exterior surfaces, such as pool decks and walkways, a broom finish is recommended. This approach enhances slip resistance, a critical factor for safety in environments exposed to moisture.

It is advisable to combine a hand or machine trowel finish with a float finish prior to applying the broom texture, ensuring that the surface is adequately prepared for use.

In the context of freeze/thaw cycles, air-entrained concrete is beneficial due to its enhanced durability. However, it is recommended to limit air entrainment to below 3% for higher strength concrete mixes, as this balance supports structural integrity while providing the necessary resistance to freezing conditions.

Conversely, for interior flooring applications, the finishing process typically involves steel trowel finishing. In these cases, it is important to minimize air entrainment to reduce the risk of delamination, which can compromise the longevity and performance of the floor.

Additionally, allowing bleed water to evaporate completely before finishing is a critical step that should not be overlooked, as it directly affects the quality of the final surface.

For those seeking further guidance, it is advisable to consult with a qualified contractor or refer to established industry resources for best practices related to flooring applications.

Troubleshooting Common Surface Issues and Delamination

Surface issues such as bubbling and delamination can occur in concrete work, despite adherence to proper finishing techniques. The presence of bubbles or soft spots in a newly finished concrete floor may indicate potential problems.

The use of hard trowel, steel, or machine finishing on air-entrained mixes can entrap moisture, leading to delamination beneath a sealed surface.

To mitigate these risks, alternative finishing methods such as broom finish or hand floating are advisable, as they promote better air release and surface openness.

It is essential to document each step of the process, including dates, for contractor records. Regularly reviewing the work and noting any issues can provide valuable insights for future projects.
