![]() In essence, the remarkable durability of concrete overlays is a testament to the meticulous science behind their formulation and application. Proper curing enhances the overlay’s strength, reduces the risk of surface cracking, and ensures longevity. The Role of Curing: Curing is the process of maintaining adequate moisture and temperature conditions to ensure complete hydration.This chemical reaction results in the formation of crystals that interlock and give the overlay its strength. Hydration Explained: Once the overlay is applied, the water in the mix reacts with the cement in a process called hydration.Any dirt, oil, or loose material can hinder the bonding process, leading to potential failures in the future. Importance of Surface Preparation: A clean and well-prepared surface is crucial for the overlay’s adherence.This is achieved through a combination of surface preparation techniques, such as cleaning and roughening, and the use of bonding agents. Adherence to Existing Surface: For an overlay to last, it must form a strong bond with the existing concrete surface.A well-balanced mix ensures optimal strength and longevity. ![]()
