Addage Block Hardener is a specialized solution formulated to fortify concrete masonry units (CMUs) or blocks, enhancing their strength and durability. By deeply penetrating the surface, it reacts with cementitious materials, forming a crystalline structure that reinforces the concrete matrix. This process effectively increases resistance to moisture, abrasion, and freeze-thaw cycles, prolonging the lifespan of CMUs. Addage Block Hardener is easy to apply via spraying or brushing and is suitable for various applications, including new construction and repairs. It is particularly beneficial for structures exposed to harsh environmental conditions, such as retaining walls, foundations, and exterior walls, ensuring long-lasting performance.
