It is a high-performance, water-based concrete curing membrane, used in the prevention of water evaporation from concrete surfaces. Bond Flexi Cure resultant film retains sufficient moisture in the concrete to ensure full hydration of the cement, essential for optimum strength development. The cured concrete with Bond Flexi Cure is typically harder and exhibits a dust-free surface with a reduced incidence of drying shrinkage cracks. The product is supplied as clear and white pigmented colors; the clear color is initially a white liquid which forms a wet white film when applied to concrete surfaces, but then dries to form a transparent film.
