- Moisture Retention: One potential benefit of applying curing compound to already cured concrete is the ability to retain moisture. Concrete is a porous material, and even after it has hardened, it can still absorb some moisture. Applying a curing compound can help lock in this moisture, supporting ongoing curing processes.
- Enhancing Durability: Curing compounds often contain additives that improve the density and strength of the concrete surface. When applied to cured concrete, these compounds can potentially enhance the durability and resistance to abrasion and chemicals.
- Surface Protection: Concrete surfaces can deteriorate over time due to exposure to various elements. Applying a curing compound can create a protective barrier that helps prevent the penetration of contaminants such as water, oil, or chemicals, leading to prolonged life and reduced maintenance costs.
Considerations and Drawbacks:
While applying curing compound to cured concrete may offer some benefits, several considerations and drawbacks should be kept in mind.
- Bonding Issues: Applying a curing compound over an already cured concrete surface may cause bonding issues. The film formed by the curing compound could prevent proper bonding with subsequent treatments, coatings, or repairs. This can lead to adhesion failure and compromised structural integrity.
- Proper Surface Preparation: To ensure effective bonding and proper penetration of the curing compound, thorough surface preparation is crucial. The cured concrete should be clean, free of any contaminants, and potentially roughened to create a suitable surface for the compound to adhere to.
- Cost and Application: Curing compound can be costly, especially when considering the need for thorough surface cleaning and preparation. Additionally, the application process might require specialized equipment to achieve uniform coverage and ensure proper curing.While it is technically possible to apply curing compound to already cured concrete, there are several important considerations to keep in mind. This includes potential bonding issues, the need for proper surface preparation, and the associated cost and application requirements. Ultimately, consulting with concrete professionals or structural engineers is recommended to determine the best course of action based on specific circumstances and project requirements.
